The 1-Watt LED Upgrade Kit converts most C and D (2-6 cell PR style flange) incandescent flashlights into super-bright, long lasting (50,000 hour) LED flashlights. It's as easy as replacing the bulb; your flashlight will emit a pure white (as opposed to the incandescent dull yellow) light. Self-adjusting for all capacity levels, this efficient LED technology also conserves battery use.
