LED modules for signs and light boxes, 12 V
LED modules are small sealed boards with one to six SMD LEDs, linked by wire in chains. Sign makers fix them inside channel letters and light boxes for even light. We supply 12 V modules to sign makers and distributors.
A typical LED module runs on 12 V DC, holds 1 to 6 SMD LEDs (2835, 3528 or 5050) and is sealed to IP65 for outdoor signs. A 3 × 5050 module uses about 0.72 W (60 mA at 12 V). Modules come in chains, so you cut the number you need.

Why sign makers use modules
Modules are linked by wire, so they follow any letter shape and spread light evenly across the face of the sign. A damaged module is replaced on its own, without throwing away the whole chain. They can light the face of a letter from inside or the wall behind it (halo light).
Choosing a module
Deeper letters and light boxes take brighter modules with lenses (160°) spaced further apart; shallow letters take small 1 or 2 LED modules close together. Tell us the letter depth and face colour, and we suggest a module and spacing. More on LED lighting for signs.
Power
Modules need a 12 V DC power supply sized to the total load plus a margin. We do not supply power supplies: buy one approved in your country.
Questions buyers ask
How many LED modules do I need for a letter?
It depends on the letter size, depth and spacing. Send the sign drawing or the letter height and depth and we work out a count.
Are the modules waterproof?
The modules we quote for signs are sealed to IP65 for outdoor use.
What is the price and minimum order?
We quote both per model and quantity.
