It Should make you Wonder

Recommended Posts


It really should make you wonder when you have a LED Sales rep / Lighting Engineer talking to you over the phone trying to sell you their LED's who are a Sign Company NOW also branching out to sell their LED's which I think everyone has seen in all the sign magazines now where they ship you off their little "light box". I'm sure you know who I'm talking about.

I asked him where their LED's are being made, "China...they're the brightest....with very little light decay and will last 11 years" he replied.

"I see........Uhh..who is the diode manufacturer?" I replied

"I Can't tell you" he said.

"You don't know?" I followed up with.

"No, I know....I just can't release" he said.

"Why is that?" I asked.

"It's proprietary information...it's our secret sauce formula you know?"

"It's a secret?....that makes me cautious actually. As you know there are a lot bad diode manufacturer's and grades of each Diode......that doesn't make me confident in not knowing who you are using" I ended our conversation with.

For a LED product manufacturer not to tell you who they are using is NOT good, it also should tell you their not that confident either. It means you will be retrofitting your customers signs out shortly after!

I'm VERY confident and PROUD to tell you what diodes we have in our products, Samsung and Nichia!

Finally we can also proudly say that these products are NOT made in CHINA!!!!

I'm starting to see a lot of LED sellers claim their products are "LM79 and LM80 certified" - yet there is no mention of what these tests actually revealed. My understanding is that LM79 measures total luminous flux, luminous efficacy, light distribution, and a few others. It's not a pass-fail type of test, it's a report that can be used to evaluate a product.

Modules, etc. from everyone seem to be getting better, but it's definitely still buyer-beware.

These tests are also used to project life of a product. I'm not sure how they take a few thousands hours and say that said product will last 30k/50k without failure or very little light loss, but they do. Neon and fluorescent easy to project as it;'s just gradual but LED's, graph it and it's all over the chart, lol.

I still haven't seen a whole lot dependability on bright products for the sign industry. The Sloans and GE's play it safe on under powering theirs and charging a whole lot for it, playing it safe is equaling out to light output compared to conventional light sources. I still see a ton of failure's all around town even with new signs, and signs hitting that 20k mark. Lot's of re-retrofitting going on and lot's of people entering the game thinking they can just bring in overseas not knowing the makeup, and as you said it is "buyer-beware"

      We always strive on information here on The Sign Syndicate.  Everything from National Sign & Subcontractor Reviews on "payments & relationships" to "How To"...better ways to build sign systems and projects based on longevity & reliability .
       
      So, we're very, VERY excited (I want to say "Super Excited" but it's so over used) to announce our whole new upcoming Sign Syndicate 24V BrightON (Pronounced like the city) LED system just got even better.  Better because we will be complimenting our High Powered, High Efficient LED Module system with France Lighting Solutions 24V LED Drivers.
       
      I have talked about France products quite a bit here over the years, mainly when it comes to Neon.  The quality, that high bar of standards, most importantly....the "Reliability".
       
      From Neon to LED Power Supplies, expect nothing different, nothing less from France Lighting Solutions.  But, actually here is something different about their LED Drivers, something "Cool".
       
      The France LED Drivers are the ONLY drivers that are "True Power". 
       
      What is "True Power"? 
       
      In short......It means they are the ONLY LED driver in the electric sign industry that you can load to the MAX.  Not the typical load to 80% - 85% leaving room for voltage loss, wiring etc.  Load to MAX.....if you want.
       
      We are just a month away from releasing the Sign Industries most light/power efficient LED Module on the market that will definitely put it's mark on this industry.  You'll be able to get the most light for very little cost of operation.  Get more for less.....be on a 24V system which give sign shops the unique ability to load more modules on a single power supply.  A 24V system reduces the heat, resistance, and amperage compared to a 12V system, you'll have more voltage headroom for longer wiring lengths. 
       
      With a 24V system you're not restricted to 60 Watts per channel, BUT 96 Watts.....that's almost double! 
       
      Complimenting our new LED System with France's "True Power" LED Drivers and adding them to your electric sign projects you'll be able to load 120 .8w BrightON 2 LED modules.  That's 76.25 Linear feet of high powered LED modules for anything from everyday channel letters to cabinet & perimeter lighting.
       
      For our High Powered Sign Cabinet Lighting module, BrightON SunFire (2.4w), that France "True Power" LED Driver will give you 40 to 50 Linear Feet for your Sign Cabinets

      Those Sign Face Foot Candle numbers!!!  Look at the "Foot Candles Per Watt" (Higher is better)

       
      Our complete High Powered High Efficient BrightON LED System with France Lighting Solutions, that's DOUBLE reliability!!!

      So, we finally did it.  It's been kicked around for months, prototypes, after prototypes and locked in on a configuration that we finally liked.
       
      As most of you know the Sign Syndicate we've been testing majority of the main stream LED's since 2008 in a unbiased benchmark comparison, tests such as "The Great White Hope....Project Tighty Whitey...Red Light District...Border Security & Blue Light Special".  Over that time we've seen some characteristics that we liked, made sense, understood what will last and won't.  What it means to be a High-End LED product.
       
      We have sold the NC LED's & Axioms for a few years now, as some of our favorites from the testing (Axioms no longer).  But it's been time to do our own, make it more custom and more perfect for the Sign Industry.  The Brighton line is made from those in the Sign Industry.....FOR the Sign Industry.
       
      It's BrightON, pronounced just like the city. 
       
      So what so unique about the Brighton?  For starters, we wanted it to be VERY efficient.  I don't know of another more bright and efficient LED module in it's class.  155 lum/W and 124lum with a 170˙ Batwing optic lens, most importantly when it comes the sign industry the important number is 63.09 Foot Candles on a sign face per Watt
       
      The important aspects of long lasting LEDs is of course finding the "sweet spot", where it's driven just perfect for light and power.  The Brighton is VERY under driven, less power, MORE light!  These can be spaced out pretty far due to the optics lens, it's brighter in angles than it is straight on, or up.  Under driving  improves thermal performance, which extends life all while getting higher Lumens per watt.  The Brighton LED is a High-End, High Performance LED module for High-End applications.
       
      For starters off the bat we will have a 2 Diode, (no need for a 3 Diode), 4 Diode, and our Sign Cabinet model 6 Diode (SunFire).  Shops won't need to stock multiple module types, the Brighton-2 is so versatile, you can use it for almost anything, just adjust the spacing.  It already comes with 7" inches of wire so jumping from one row to another is easy.  Space the center to center at 6" for good light, 5" center for Better Light, 4" for Best Light.  They're 1.7 mods/foot and work good for shallow 2" applications depending on face type to of course much deeper.
       
      Since these are driven so low, they don't generate a whole lot of heat, BUT, our Brighton-6 (2.8w) is Heatsinked on all Aluminum PCB for longer life.
       
      One of the biggest complaints we have received about LEDs when it comes to large projects like large letters or cabinets is......"We have to use so MANY Power Supplies!"
       
      A nice aspect about the Brighton is, it's a whole 24v system!  Everything!
       
      As sign companies we are redistricted by the Class II regulation of no larger than 5A per channel.  So 12v is restricted to 60watts, BUT....24v is restricted to 96watts.  24v will mean more modules per power supply.  You're now getting almost double the amount of modules for a project.
       
      24V cuts that amperage that runs across the wiring and module in half!  It reduces the resistance, reduces the heat and most importantly IMPROVES reliability.
       
      I think we can all agree that LESS is BETTER, less moving parts, the less you have to worry. 
       
      This is the first part of our Brighton Line, we'll continue to improve it widening the line and of course always always staying far ahead of the curve
       
       
      I'm including some rough test pics of our process and how they fair.  We should have these available in the first part of Fall.
       
      And yes, we will still stock, and continue to sell NC LED Reckless LED
       
       

       

      Early Try Out's, various wattage and diode mfg's

      So...
       
      I haven't posted any jobs lately and I need to play catch up.
       
      So I'll start with our latest projects and work myself backwards
       
      As we've discussed so many times on the Sign Syndicate.  There is a time to retrofit, and a time not too.  Neon and Fluorescent lamps/systems should not in most cases be retrofitted to LEDs unless accessibility calls for it.  Otherwise, it doesn't make financial sense for the consumer to do so, or....just so a shop can make a project sale on BS energy efficiency numbers and mythical saving $$$$

       
       
       
      So here are some retrofit jobs that make REAL sense.
       
       
      NEON RETROFIT
       

       
      Here's a chain of Studio's that I've been doing since the early 2000's. 
       
      This particular sign is only partially mine, everything from the Logo and red letters. 
       
      This was the first job I did for them leading up to fabricating all new signs for their locations.  The white is from the previous location and Neon has been in it's original form since the late 90's, and it's 6500K Snow White.  The logo is 15mm Tri-phosphor, Elite 65D I believe.  The Logo and Red was done in 2008.  It's very hard to tell because red and white is hard to capture and a cell phone cam does no justice but the White lettering is dimmer than illustrated and is about 50% of it's original light output. 
       
      Not bad for 20+ plus year old lamps!!
       
      So the owner called up and wanted a revamp.  Had I been the average shop you bet the immediate response would have been LED!  SAVINGS!!!!!  BULLSHIT!  BULLSHIT!
       
      Well, no. 
       
      We're logical over here in SoCal, a land where 50¢ modules would have replaced the Lamp Art.
       
      The logical choice, and more economical choice for the consumer?
       

       
      Going from a single halo phosphate 6500K Snow White Neon lamp to a Tri-Phosphor EGL Designer 7100 Series Lamps.
       
      When we moved and installed (2008) this sign we did so with Tecnolux Silicone GTO and Caps.  All that was needed for this retrofit was new lamps, and leaving the awesome silicone GTO and transformers in place!
       
      Now, I owe you a night shot, the iphone pic I took was garbage, so I'll update that soon.  But the Logo and White letters match up well, and even with the old faces, the sign illuminates like a new sign at night. 
       
      Forgot to mention, the white faces are also from the 90's and they've held up quite well, the Trim Cap is Plasco, also held up quite well for 20+ years old.  During the day, the ace look good, so no need to replace.
       
       
      LED RETROFIT
       
      So a new client...
       
      They called, they were moving and wanted to know if they needed a new sign or whether to fabricate a whole new on because the current was lit up like crap.   Had hot spots, dim a places, and just crazy outages in sections of letters.
       
      It would have been better had I taken night pics, BUT...I didn't know I would be posting and writing about it here so
       
      Had this been some other shop, I'm sure the nightmare would have continued
       

       

       

       
      Yes, two different LED manufacturers in the same sign Woohoo, the electric sign industry in it's finest form right here!  It made me SO proud!
       
      If you're familiar with Gaverieli Plastics, I need say no more, let alone Chinese JS LED's....well, their both China and their both crap. 
      They don't last, they fail, they cause companies problems with having to go back and replace and most importantly...They cost the consumer, YOUR client.
       
      The second sign which they had, made at a different time and by another company was US LED, also garbage.  Illumination was just as bad.  Sorry, didn't get pics of that sign because again, it wasn't my plan to make a post here
       
      If this wonderful, thoughtful sign package doesn't make you cry, I don't know what will.
       
      The original plastic was green vinyl over white acrylic and in such a short time this sign was beat, and probably why they called a new contractor for the work for their sign move.
       
      Well, a new sign made no sense. 
       
      They were just moving a few suites over and they weren't going to get a larger sign so the original would do.  New faces with 3M Lime Green over White acrylic.
       
      The most important aspect of this Sign....
       
      Yes! 
       
      NC Reckless-3 LEDs.  Top Tier Samsung Diodes running on a Constant Current system...NOT Constant Voltage.  1.2 watt modules.  Most important detail about our NC Reckless LEDs?  Their made in Korea NOT CHINA!!!
       

       
      Beautiful!
       

       

       
      Check out that crazy light meter reading!  That's almost 300 surface Foot Candles, which is about the equivalent light output to a 13mm Tri-phosphor white Neon Lamp behind white acrylic.
       
      If that is not simply utterly gross and disgusting, and you're not just sickened by that number, you have no stomach
       
      These Reckless-3 LEDs will NOT be powered up by their low budget power supplies but rather our Union LED Power Supplies made in KOREA, not CHINA!!!
       
       
       
       
       
       
      It's usually best to retrofit out with what was already in a sign, and not change one light source to another.  It's makes more financial sense in MOST cases, not all, but most.

    • Most Light Source Suppliers and Manufacturers won't show you examples let alone "numbers" of light readings on Sign Cabinet or Sign Projects from light source components they push like these I'm posting here, but....This is The Sign Syndicate!   "Seeing is believing" as they say.   So, one of the components I've been big on because of feedback and demand is a strong enough LED module that doesn't cost an arm and a leg, isn't proprietary where you need to buy their special clips, brackets, etc, and actually put out enough light without exaggerated "Usable Light" under too far spread spacing that's supposed to save you money that won't compete with other existing signs in the area of your project.    Biggest complaint from sign shops about cabinet LEDs....."I don't want to use a whole bunch of power supplies!"   You want your clients sign to stand out, NOT be lost or drown out by other neighboring signs also competing for attention and visibility.   Most importantly, the BrightON Sunfire LED keeps it simple by allowing custom sign shops not having to pay enormous amounts of money.   I've discussed our upcoming new High-End Sign Syndicate BrightON Sunfire LED for Cabinets, Slim Cabinets, and Large Channel Letters before.  But I've never had an opportunity to back it up with facts by illustration until now.   Let's start with our industry long time standard light source components first.    That is good ol HO T12 Fluorescent Lamps.    Unlike our industry suppliers and manufacturers I'm not going to bash the use of HO Lamps, they work good, and they do last a long time despite their marketing claims of failure just to sell another light source.  There are some very well High-End made HO Lamps for our industry.   Back to the project.   Here we have your typical 4' x 4' x 12" double sided cabinet that we would either see on a pole or mounted on the ground.    3/16" 7328 Plexiglas MC acrylic face.  Using industry standard spacing of lamps at 12" spacing.        HO Lamps 6" in from the sides and 12" from lamp to lamp powered by a energy efficient electronic ballast pulling about 126 Watts         With four HO 4' lamps with 12" spacing we have a average Foot Candle average right on the sign face of 156.5 FC    This is, and has been our industry average for sign surface lighting for DECADES.         Here is our High-End Sign Syndicate BrightON Sunfire  (pronounced just like the city)     A 3 watt LED module with a 170˙ High Uniformity Optics with over 420 lm   Most importantly it's 24V system, and Constant Current.... NOT Constant Voltage.    This system has reduced amperage, heat, and resistance running across it compared to a 12V and it has more voltage head room for long runs.  This calculates to longer life.  On a 24V system this means loading more modules on a 96W power supply than a limited 60w power supply of a 12V system.  Less moving parts on a project the better.     Below and as illustrated we spaced our modules the same as HO Fluorescent Lamps.  6" in, 12" from row to row and one Sunfire Module per foot, spaced 12" apart from one another   One thing I wanted on our Sunfire modules were longer wires between each module.  You have enough wire (15") to jump from row to row without having to splice...less labor involved and it gives you more room to do what other tasks you may need to do with longer wiring.   Using modules like our BrightON Sunfire makes your projects at so much of a lesser cost.  Instead of buying special proprietary clips, tracks and mounting brackets just purchase inexpensive alum 1/16" or 1/8" angles and channel for mounting.  These typically can be bought in 8', 16', and 24' lengths.        The results.....196.5 Foot Candle average on the sign face surface, a 26% brighter face       What makes the BrightON Sunfire even better?   Adding a True Power France Lighting Solution 24V LED Power Supply.  True Power means having the ability to load 100% of a load on a power supply.  As you know most power supplies are asked to load to 80%-85%.  Not so with France, 100% if need be.       Most competing cabinet 12V/24V LED modules will run you anywhere from $7.00 to $15.00 per module.    The BrightON Sunfire will only run you $3.75 per module, giving you NOT "Usable Light" but "Real Competitive Light" as illustrated here.....26% brighter, over above our industry standard lighting of T12 HO Fluorescent Lamps!!      
    • Our 24V France "True Power" Lighting Solution products that will power our Sign Syndicate Brighton LEDs have finally arrived and are now listed up in our Online Shopping Cart.   You'll be able to power up 118 .8watt BrightON II LED Modules on a single 96W France LED Power Supply for all your channel letter and sign cabinet  projects!!!    That means cost savings in using less LED Power Supplies in using a 24V system over a 12V system.    A 24V System also reduces the Amperage, Heat, & Resistance running across your LED Modules over a 12V system   Two HUGE pluses for your projects, High-End, High Efficiency Constant Current 24V BrightON LEDs powered by True Power France Lighting Solutions Engines.
    • Large outdoor LED display is a high-tech engineering product integrating multi-disciplinary technologies such as electronics, power, computer, communication, information, image processing, optics, materials and structure. The relevant engineering and technical problems in any of these subject areas will affect the final operation of the entire display. A perfect LED display must be an organic combination of multidisciplinary technologies. Led display dot matrix module driver is generally completed by a constant current driver chip. The chip includes a serial shift register, serial-to-parallel conversion and constant current driving and other functional circuit components as shown in Figure 1. The constant current chip is a conversion device that converts the luminance signal of the controller into an appropriate driving current for driving the LED to emit light. The quality factor of the constant current of the constant current device will affect the effective brightness of the Exhibition LED Display Shenzhen. Especially when the refresh rate of the display screen and the number of display gray levels are higher, the constant current chip will more significantly affect the brightness of the entire display screen. As shown in Figure 1, the supply voltage V-LED of the display will also be one of the important factors affecting the brightness, especially when the voltage is lower than the normal on-voltage of the LED, the LED illumination effect is affected, thus affecting the whole The brightness of the display. In summary, in order to solve the brightness problem in the display application, we can take practical measures including: using high-brightness chips, high light-receiving rate to select Indoor rental LED Screen, and designing pre-sufficient while ensuring white balance brightness requirements. Appropriate pixel point combination design to ensure reasonable pixel viewing angle, increase the visual contrast of the display through reasonable arrangement and structure design of the lamp; select high-quality constant current driving chip for reasonable driving current And voltage design to ensure efficient driving of LEDs.   Of course, ensuring efficient LED driving requires strong R&D and technical strength. The LED video wall display china industry has grown rapidly in recent years, and has also grown up with a number of excellent display applications and display light source packaging companies, such as display light source packaging. Enterprise--Bai Shi, after years of development and growth, now has its own display R&D lab, dedicated to the research of LED display technology, and a large number of LED display application technologies in the United Nations key research institutes. research work.
