Sign Syndicate Light Testing Results - LED Failure
1 1

1 post in this topic

ANNOUNCEMENT:

The Testing for all our light projects will resume Starting this month next week. The last results were posted on this site last September. We have taken the November 2012 evaluations but never posted them. We have just finished with February's test results and will be posting those next week as well. We will be changing monthly reports to bi-monthly reports. I have started acquiring newer modules from various Board vendors as well as non-vendors to add to our projects.

A new test we will be introducing right before ISA is "Blue Light Special". This will be a small test like The Red Light District with a few select vendors. Blue LEDs are a very hard find. Many manufacturers market they have a blue line but very few actually produce any you can find at a distributor or supplier so we will stick to those who have their products readily available sitting on a shelf.

In doing our February test results we came across a failure of a light source mfg product that we have had in The Great White Hope for over 26,000 hours. Below is a video update of The Great White Hope

      ---> Sign Syndicate Special 100 RECKLESS-2 NC LED Modules for $99.99 <---
       
       
      As some of you may already know The Sign Syndicate has been testing NC LEDs since 2010 in Project Tighty Whitey, The Red Light District, & Blue Light Special and after the first 8,000 hours I was pretty impressed in "PTW", even in that short about of time we saw no light degradation (Lumen Maintenance). So I was always interested to see how they progressed, err....regressed in light as time went on.
       
      As many of you know, I don't use LEDs as a primary light source for channel letters unless I have too.
       
      When I have had to use LEDs over the years I've always been real careful about what LED manufacturer I use, and there is a VERY, VERY short list of who I use/used because I'm one of the few electric sign manufacturers that offers my clients a 5 year electrical "Worry Free" warranty that INCLUDES labor to change any electrical component out and I stress....."I"...chose to use for their sign.
       
       
      For this very reason you can pretty much chuck most LED marketing brochures in the garbage that states their LED's last 50,000+ hours of operation without loosing any light output. Most of the time they've never even tested their own to see how long they last of they take a result of 2 to 5 thousand hours and project to you the consumer those results which usually show little to none and project them in a slow gradual path of light loss. You can't do that that with LED's, but you can when it comes to light degradation with Neon & Fluorescents who have a much larger case history to go off of and it's just phosphor loss unlike LEDs which have so much more to loose.
       
      Most sign shops stick to the 1 year state mandatory (contractors licensing law) warranty, and "optional" or limited component warranty that does NOT include labor for up to 5 years. So should some component YOU chose crap out on your client then I guess they call you, you get a free replacement from the manufacturer and YOU end up charging YOUR client to replace something YOU specified out.....oh real nice!!!
      With my clients I put my money where my mouth is, so that's why my list of who to use is short, if it goes bad because of what I specified out I eat it, NOT my client!!!
       
      5 years is a long time, and those who pay attentions to the 3rd party testing that The Sign Syndicate has been doing since 2008 knows most LEDs don't last as long as claimed, at least when it comes to "usable" light.
       
      I've been using NC LED for a particular program for a few years now where I have to use LEDs because the use of electrical component clearance is impossible for Neon. Over the years the results have been awesome using NC LED, and of course happy clients.
       
      The main reason why I choose to use NC LED for my program before we even started selling it here which is obviously recent, is because from the testing we have been doing here namely Project Tighty Whitey as it applies here.....there are a few things in common the brighter white LEDs in the comparison that last longer than others have in common.
       
      1st....Their made in Korea, very tight quality control, think "Japan"!.......NOT China where they have quality control issues. Don't let anyone tell you different, there is too much of a track record and case history for INCONSISTENCY and manufacturers have to constantly hold the hand of the Chinese to make sure they're getting consistency and this is why American companies play musical chairs with Chinese plants who make their products.
       
      2nd....Their constant current, or current regulated on each module...NOT constant voltage aka "Eco". So if you're not familiar with that term Constant Current just know each module is 12 volts from the first to the last on a string. A LED module that is ...NOT CC is constant voltage, aka "Eco"! Those are unregulated and the first LED module on a string is different than the LED on the last, or middle. It also means the first LED on the string could be taking a big hit from the power supply because it's not regulated and you'll get faster degradation as well as uneven lighting.
       
      CONSTANT CURRENT vs CONSTANT VOLTAGE
       
       
      This is not to say others that aren't with similar characteristics will last nearly as long (there have been exceptions), in past versions degradation over 15,000 hours or 5 sign years is left on 8 hours a day has been about 0 to 3% of the original illumination, that's something that should interest you and the end user, and newer versions only get better with heat dissipation.
       
      NC LED come with three different diode manufacturers, SOL, LG, & Samsung ("Reckless"). I took a personal hand for us to use SAMSUNG, their white is brighter than the other configurations, it's more of a true 6500 white, and you need bright! The LED colors that we stock are SOL chip.
       
      Every LED manufacturer has their marketing claims on Lumens, Viewing Angle, Lens..no lens, etc etc etc. From the Neon & LED testing we have been doing here on the Sign Syndicate they can throw all that out the window because it doesn't translate into anywhere when it comes to the sign industry, how we use them, and how it makes them last over time. 90% of the time it's just a sales pitch to throw at you on why you should buy their over another one. Who cares about Lumens when it comes to signs...we light up a sign face and only care about surface light! Viewing angle??? Don't get me started!
       
      What do we care about being in the sign industry? That it's bright, and most importantly it lasts over time....well...at least the client does more so than the sign sign shop because it's them who will have to pay to re-retrofit to something else.
       
      So, we're very happy to offer the NC LED "Reckless" light source product to our members that we know works as an option for your sign projects here on The Sign Syndicate. It's nice to add another High Brightness LED to our line up, AND the Reckless-2 is the brightest LED in it's class of under 1 watt per module and under 3 watts per foot than anything on the market today!
       
      If you're the type of shop that just likes to stick to big name LED manufacturers because you think you're playing it safe and you're also not too familiar with the testing The Sign Syndicate has been doing since 2008 let me just say this. From all the testing we have been doing with out benchmark testing, and we've talked about it a lot in the past. You pay a lot of money to big name LED manufacturers and the product itself is most of the time is average and most a lot of times subpar compared to what's out there from a few small select LED manufacturers. You pay a lot and you get very little. What I mean by that is, you don't get a whole lot of light in return and you could pay significantly less and get a brighter light output and a product that will even last longer. Not all big names, but you'll have to download the quarterly results that we have in the Board forum and judge for yourself.
      Like I said, there are VERY good results from a FEW select companies in Project Tighty Whitey and NC LED is one of those few, AND that's why I'm very proud to offer it to our members.
       
      Why leave money on the table choosing someone else and why not have a more satisfied client using NC LED?
       
      NC LEDs come in both forms, Constant Current "Reckless" as well as Constant Voltage "Eco"(ECO Series), we will be concentrating on the Constant Current versions of these LEDs
       
      Basic NC LED Specs
      • IP68
      • 5 Year, 50,000 Hour Warranty
      • Constant Current (Regulated) not Constant Voltage like cheaper "eco" LEDs
      • Made in Korea.....NOT made in China
      • High Brightness LEDs
      • Samsung Diodes for white
      • Sol Diodes for color
      As I stated above, we're offering 100 of the most versatile NC LED "Reckless" Modules which is the two diode Samsung configuration, the Reckless-2 powered by Samsung for only $99.99
       
      Specification Cut Sheets (Updated 4/25/16)
      NC SS Brochure.pdf
       
       
      Lastly I need to mention that I power up these bad boys with our Axiom LED Power Supplies. I've been recommending these LED Power Supplies for years, FAR beyond the time we even started stocking and distributing here on the Sign Syndicate.
       
      The Reason? Their small, their all metal body for dissipation in heat, their military grade, you can run them on a 90-277v circuit.
       
      Unlike a lot of those cheap $18 power supplies that "MeantWell" can usually only handle a full load at 40˙C. The Axiom Power Supply that can truly handle a full 60 Watt load can do it at 60˙C, and operate at 70% at 80˙C
       
      So if you're burning out those cheap import Chinese LED power supplies and you can't figure out why and you're very close to the load limit your 60 watt power supply can really only handle a 40 watt load because of make and due to the environment in which it's in.
       
      Another perk about the Axiom Power Supply, there is an onboard LED diagnostic light that tells you if you have too much load.
       
      Lastly, if you're still NOT using constant current LED's this power supply can be a big plus for you in attempting to correct YOU for not using constant current LED's and that is there is a manual adjustable screw that can change the voltage from 10.5 to 15v. Why does this power supply have this? Though the voltage change will not harm constant current LED's or change the light output it can help when using Constant Voltage LED's. Since constant voltage LED's are not regulated and you have a sign with multiple circuits of power supplies and you have really long runs of more load on one than the other your light output will be different because the voltage has dropped. With the adjustable screw you can hook up a meter and assure the string is at 12v, rather than one power supply at 11volts and others at 12v. The slightest fraction of a volt can change the light output making it dimmer or brighter. The slightest fraction of a volt on constant voltage LED's can kill it as well.
       
      So for these very reasons and feature of the Axiom LED Power Supply this was the choice and only power supply we have used of the Sign Syndicate Light Test Comparison Projects. 40,000+ hours of operation over 30 units since 2005 and NEVER a failure....that's 13+ sign years folks!
       
      AXIOM LED PS60

       
      Recently we have also added a 2nd power supply to our lineup.  The Union Elecom 60 watt and 120 watt (Dual channel) LED Power Supplies.  These LED Power Supplies are IP68, and  fitted with 1/2" nipples so you can simple hook up the primary with a junction box that has 1/2" thread knock-outs so you don't need a Transformer Box
