I have converted some of my Mag lights to LED. They work great and are plenty bright. The best part is that the LED uses so little current, even old and especially cold alkaline batteries still yield an oh-my-gosh bright light. I hate grabbing a cold, flashlight with a dull yellow beam when I have to go out in the winter. There are retrofit bulb/reflector kits for ALL the maglight series. On the two minimag's I keep in the vehicles, I have 1W LED's and pushbutton endcap switch that has 5 settings. High, Med, Low, slow flash, and fast flash. These came in a kit with the LED, new reflector and endcap switch.
