Nite Ize LRB2-07-PR Upgrade Kit, LED Lamp, 55 Lumens, 100,000 hr Average Life

The LED upgrade kit converts most C and D (2 to 6 cell PR style flange) incandescent flashlights into long-lasting 55 Lumens LED flashlights with a 100,000 hr life. It is easy as replacing the bulb - instantly, your flashlight will emit a pure white (as opposed to the incandescent dull yellow) light, in spot to flood focus. Self-adjusting for all capacity levels, this efficient LED technology also ensures a much longer battery life, making it not only a useful, versatile improvement, but environmental friendly and pocketbook-friendly.
