I have done MagLED upgrades with most of my 2C lights and all of my 3D lights. I am very pleased by the output and longevity of the lights. Superb product.

The Nite-Ize upgrade for large MagLites has very low output with super long runtime. It has a niche as a survial type light. I have put these in a couple of the 4 cell dorcy lanterns for use as long running emergency lights.

The Nite-Ize upgrade for 2AA maglites is a decent product. I like the smooth flood beam and long runtime. Plus it is much more reliable than the stock incandescent bulbs that pop when you drop your light. This upgrade works good for map reading and other inside vehicle needs. I add a bit of clear contact paper/film (contact brand, available at wally world) to the lens as a diffuser. This smooths out the LED artifacts and increases the flood. Nice upgrade in my opinion.

My other 2C maglights have been modded with three CR123 batteris and 6 cell MagLite Xenon bulbs. Very sweet sleeper lights. It's a small package that will out do a stock 6 Cell maglite. If you like playing with or modding flashlights come join all the fun at:

Beware, flashlights can be every bit as addicting as preparedness kits.
