Thin stroke Neon Letters

Recommended Posts

I am looking for someone to bid making some neon Reverse channel letters.

The drawing is called out for LED's Which we can do but the landlord is requesting Neon.

The letter stroke 1 1/8" looks way to thin for neon. How thick of stroke do you need for proper neon spacing?

Anybody out there willing to give this a shot?

Not fun.

I'd embolden the letters and go at least with a 2" stroke, and use 12mm minimum. Is the design with this wireway typical to that center, or just for the client? Going to have to reconfigure that too.

Well, just saw that this is a national brand so, so much for altering it to give it more room.

Maybe tell the Prop MGMT that according to the NEC code you can't make it neon. Tell him you need at least a 1-1/2" space on all sides around the neon so the alternative is LEDs or you'll have to make it an eyebrow sign/underscore sign (if that's the right terminology)

?? I'm lost here. Your tag shows you are from Priority signs, as well as the layout you reference? Priority isn't a small bit player ---- however, in the drawing it's showing for led, specifically Sloan? I'd question that part, as to why? You show a 2 1/2" letter in depth - not enough for neon because you'd have no room for the neon if you do double backs, and if you use housing, you have no room in the stroke of the letter, unless you find about 1.5". By code - you need at MINIMUM 1/4" on edge of glass to the metal. IF you were to use 13mil, you'd be CLOSE - but you better have a tube bender that can actually follow the lines for the glass = if not you'll be popping your 2161 transformer all the time.

The job is doable - if you broaden the stroke a bit, CAREFULLY plan your layout for glass, deepen the letter, etc. And this is based off a really, really quick peek of the layout and guestimating your stroke. You show 1 1/8" ---- but if that's measured from the face of letter, and you still would have to subtract the two sides of .063" from that ---- well, you get the idea of how much you'd have to broaden the stroke.

If you go back to the planned leds usage - reconsider other leds for brighter halo effect.

If you just throw out there to bid - with no caveats - you will surely get someone to say "yup, I can do it" without any question. Be careful.

On another note - how did you guys come out doing the Gerber Auto conversion?

Erik - where do you come up with UL spec of 1 1/2" on all sides of neon? Not true.

I know that, I just threw out some bullshit to use LEDs and make it easier.

It's in standard UL shop drawings when using a 15,000 to bare metal BUT it's never interrupted or not too well to the ignorant, just thought that could be used as good "bullshit" :thumbs:

If I could use LED's I would make this myself. I got the call today that the landlord is requiring Neon. I told our project manager to run the other way.

We are having the drawing revised to reflect 2" stroke and let the customer approve or reject it. I have found these forums to be very pro neon so I thought that I might find somebody that could do it and be in there wheelhouse, cause I don't want to see this one come thru ours. We don't make any neon in house and are just to busy to be messing around with a one off project like this.

This forum is pro neon...but more pro to having a safe, UL approved sign. Making the neon is easy but its the rest of the specs that would be tough. Thats why I said to be careful if you just throw it out there and someone just wings it. I do like the touch of putting moding in the raceway to get rid of the raceway look! Wouldnt quite do it like they describe.... but close. But alot of changes/clarifications would be needed, for sure.

Eric, The 1.5" clearance is between the unprotected wires and metal..not the distance between glass and metal, nor a protected electrode and metal.

Let us know what happens with this sign.

THe spacing is for the bare wires to metal but also the capacitance created from the tubes. If you stay with a 7500V tranny you can go 1/4" from metal. I would do a virtual ground on it as well. @inch depth is the deciding factor though.

As I have been taught years ago, for neon the minimum stroke width is 1 1/2"/ The assembler has to be able to get his fingers into the channel to install it. The minimum depth is 3 1/2 inches if you use Electrobits brand hardware. BUtr yu make life easier for the assemblers if you make the stroke 2 inches minimum.

I can fix this drawing for you for a price. Contact me.

Anyone consider making the letters out of plastic? We do a lot of custom carved/formed plastic where metal will not be a good thing. Haven't got time to look at the drawings today but if they are interior letters the plastic option works great.

As this drawing sits right now, it's a neon nightmare. Theses are the types of signs that end up selling tons of LED's because this sign will be arcing and burning from many places. Sometimes, when letters can't be made wider and deeper, LED's are just a better fit.

I think as the sign company you HAVE to tell this customer that it would not be in his or your companies best intersest to use neon in this application. And if he wont budge, tell him to find someone else. I would not be involved in this project as it sits right now.

If he insists on neon then you have to insist on enlarging the letters.

This is like telling GM you want them to build you a new car, but you do not want brakes! (sorry, I use a lot of auto annalogies).

Sometimes you can not allow the customer to tell you how to make a sign.

    • Like new Roland VersaCamm VS640 printer for sale - prints white & metallic inks - it needs a print head, but other than that, it is in immaculate condition.  You can't even tell we have printed on it I have kept it so clean.  I think it is about 7 or 8 years old.  We are getting a new printer, so I have to get this one out of the way before we can set the new printer up.  Will come with all of the RIP Software (Roland VersaWorks)  - Excuse the dirty floor!  Had a large project going on in here so I haven't had time to clean!  LOL             Make me an offer.
    • 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.
