This upgrade converts incandescent Maglites to LED. Does NOT fit Maglites that are LED from the factory
Warning: Last items in stock!
The Firefly 800 high powered led bulb is an instant replacement for the incandescent bulb in any D cell maglite including the older style with no "D" in the serial number. This does NOT fit Maglites that came from the factory with an LED such as ML300L.
To install the Firefly 800 lumen dopin, start by unscrewing and removing the head of your Maglite flashlight. Next remove the factory reflector, bulb retaining ring and bulb from the switch tower (if you have the bi-pin bulb you can press down on the tower to eject the plastic bulb holder). Reinstall the bulb retaining ring. Next remove the bezel and lens from the top of the Maglite head. Insert the Firefly 800 lumen bulb into the head (if you have an older version of the light you may need remove the extra set of rings that is on the base of the Firefly fist so it will sit deeper in the head). Place the lens over the dropin and thread the bezel back down until snug. Screw the head back on to the maglite until it is just "snug" onto the body.
How to use this bulb in any size Maglite.
