First post. I modded my penlight to accept a Best Hong Kong 100ma white led. The led is a 50 degree 5mm and besides being a wider angle its not near as blue as the oe led. I use this when working under the hood of cars and man it puts out a lot of light. The fit is tight due to the heatsink and I used a 100 ohm 1/4 watt resistor. If your not familiar with these they take 3 AAAA batteries.
