LiteXpress LED upgrade Modules LXB435 and LXB430 can be used to upgrade original Maglite Krypton / Xenon version flashlights with 2 batteries of the series S2D015/016, S2C015/016. DO NOT use for Maglite with 3 or more batteries! Light output 435 lumens. Easy to change, just like a conventional bulb replacement. Integrated overheat protection, plus extra heat-conductive housing of the module. Energy-saving up to 10 times the run time compared to the Krypton or Xenon versions. High shock and vibration resistance. If you own a Maglite with a Bi-Pin Xenon bulb, the white adapter must also be removed (simply pull it out as shown in the video). Maglite flashlight, which have been equipped with LEDs from the factory, can not be converted with these modules!
