Originally designed for LCD gauge displays, these backlights are encased in a 2.2mm thick diffusing acrylic that spreads light evenly from just two internal white LEDs. A built-in reflector on the flat side directs all light output through the top surface, maximising brightness. Drive it just like a standard LED at approximately 3V and 30mA. The diffused surface can be masked with vinyl, drawn on with markers, or tinted with colour gels for creative effects — making it a great alternative to EL panels for wearables without needing an inverter. Key Features Uniform Diffused Light – Special acrylic evenly spreads light from two internal white LEDs Built-In Reflector – Flat-side reflector directs all light upward for maximum brightness Simple to Drive – Operates like a standard LED at ~3V / 30 mA Customisable – Mask with vinyl, draw with markers, or use colour gels to change the hue Brighter Than EL – Higher brightness and lower power consumption than electroluminescent panels, with no inverter required Specifications Diameter – 50 mm Thickness – 2.2 mm Shape – Semi-circle (dome top, flat reflector bottom) LED Colour – White Operating Voltage – ~3V Operating Current – 30 mA Ideal For Wearable electronics and costumes Custom indicator lights and gauge displays Art installations and light-up projects Backlighting for small LCD panels Note: This backlight is rigid acrylic — it is not flexible.
