## Overview

The Adafruit 1621 White LED Backlight Module offers a large 45x86 mm illuminated area with a single white LED encased in a 3.5mm thick acrylic diffuser. Designed for efficient 3V, 20mA operation, it provides bright, uniform lighting ideal for wearable electronics, props, and LCD backlighting without the bulk or power demands of EL panels. Sold in packs of two, these rigid, panel-mount LEDs enable easy customization with gels or vinyl masking.

## Description

These pretty strips of light are plastic diffused backlights, often seen in LCD displays. Normally they're tucked behind the LCD and shine white light from below. Here, we've got the LEDs available individually and they're really cool! each LED is encased in a 3.5mm thick strip of a acrylic. The acrylic strip is a special Type that is very good at diffusing light, so even though there is only one single white LED, it provides near-uniform lighting. The other flat side of the strip has a reflector on it so you only get light from the top (otherwise the backlight would lose 1/2 the brightness unnecessarily). you can treat this backlight just like an LED, light with 3V at 20MA current and you get a pretty shape that you can mask with vinyl or draw over with marker. Gels can be used to change the color. We Think these would make great wearable electronics without the need for El or inverters, they're much brighter than El and use less battery. The trade-off is these are not flexible at all.

Review: Cool Light - Spendy - AdaFruit LED's. 30mA is where I think the big ones work best/brightest, but they provide plenty of light at 10ma. 5v USB power and a 100 ohm resistor and you are done.
Review: Really great item - Yep! Works great and there are TWO! Used it to light up a BR2049 wallet concept to make a prop replica. A wee bit long, but if you plan it out right, it will work easily and well.
