LEDs in Flourescent Bulb Light Box

[supu249]

Hey,

We have a client who has an old light box on their building. We have replaced the acrylic and new printed translucent vinyl. Unfortunately, the flourescent bulbs wont light up. Instead of trying to diagnose the specific problem, I thought why not put some of those LEDs that channel letters have inside them. I have tried to search online, but mostly all i find is long LED tubes that use the existing flourescent tubes mounts. Cant i just glue the LEDs to the back of the box on the inside? I know if need enough LEDs to avoid hotspots. Thanks in advance.

Yes, there are several brands that you can use.. What is the size and depth of the box? The depth will determine the type of LED that you need..

It really is as simple as you put it.. Just need to get the right LEDs.

Here are some links to get you going..

These are 2 of the more popular known brands to me.. We use GE for exterior.. Great product.

Good Luck~!

we retro quite a few boxes, S/F as well as D/F. *the one thing to remember if you decide on the GE tetras, GE has a different output voltage on their LEDs,
24v whereas most other manufacturers are 12v. just be aware of this when servicing the LEDs as well as the power source takes place.

The box is a 3x6 and 8 inches deep. Thanks to you both for the quick replies.

if you cant diagnose a 3 lamp sign you have no business selling/installing an led lighting setup.

Jesus Dude.. Take it easy..

We all learned how from someone else at some point..

Exactly, so instead of trying to sell someone on an led conversion becuse they think its the easy way out and just a magic solution why not learn one of the easiest setups to diagnose and fix. It could very well just need lamps, or worst case a ballast or sockets.

As I previously stated if you cannot diagnose a simple fluorescent lamp system I have zero confidence you could correctly wire a power supply,switch, make led jumps in a craftsmanlike manor.

Because the guy specifically said he did not want to diagnose the problem with the current setup.

I am about to do my first Florescent to LED conversion with the tube LEDs. So I am learning from this post. I've done many retrofits with modules, but never a bulb.
There is a box cabinet on a pole that is 4' X 6' it has (4) 72" bulbs HO. Do I need to remove the ballast and put in a 24 Volt Power supply? Will the sockets need changing also? Thanks

Rip out the old guts. Throw them away.
Go to your local sign supplier and get a bag of standard 6000k sign grade LED's and a LED 12V ballast.
No need to use expensive tubes. Use a string of LED's
String the 12VDC LED's around the inside of the box. Wire up the 12 volt ballast.

Done.

I doubt 115 lumen LEDs are going to be bright enough.
