High Power LED Upgrade Kit For Most C or D Cell Flashlights

Flashlight Accessories

Reliable, efficient, economical, and bright. You may not have those things in your brother-in-law, but with our 1 Watt LED Upgrade C & D Cell, you can at least have them in your flashlight.

Product Information

The Nite Ize 1 Watt LED Upgrade Kit converts most C & D (2-6 cell PR style flange) incandescent flashlights into super-bright, long lasting (50,000 hour) LED flashlights. It's as easy as replacing the bulb - and instantly, your flashlight will emit a pure white (as opposed to the incandescent dull yellow) light, in spot to flood focus. Self-adjusting for all capacity levels, this efficient LED technology also conserves battery use, making it not only a useful, versatile improvement, but an environmentally-friendly one as well.

Product Details

  • 74 Lumen Output (Estimated Max Lumen output only. Actual performance depends on operation conditions, cells used and flashlight.)
  • Fits Most 2-6 cell C&D cell flashlights - PR Flange Style.
  • Simple to Install - As simple as replacing the original bulb.
  • Environmentally Friendly- Minimizes battery waste and bulb replacement waste… Lighting the way for our sustainable future!
  • Save money on replacement batteries and bulbs.

How many volts can the 1 Watt LED Upgrade for C & D cell flashlights handle?
This product was designed to handle between 3-9 volts.

How much longer will my batteries last using the Nite Ize 1 Watt LED Upgrade Kit - C/D?
The answer depends on the number of batteries your flashlight uses and what type of flashlight you own. Because of these variations that exist the results will vary. As an estimate you can expect batteries to last twice as long as the performance of your flashlight with the original incandescent bulb installed.

    Purchased this lamp at Lowe's to replace the lamp that went out when I dropped the Maglite. Simple and easy install, and is better than the original lamp. Great product and I would recommend it to anyone that needs a replacement.

    This does everything it says it will. It is well worth the money and that says it all. Makes the Maglight company upgrade look pitiful. My 2D cell now works better than any flashlight I have seen and I have seen a bunch.

    Wow! Best LED upgrade for any of those old 2, 3, or 4 cell flashlights yet! Upgraded several.

    I've owned 3 of these over time and have installed them in various D cell flashlights (and even hastily hacked one into an AA flashlight to see what can be achieved). As far as LED mods go, the 1 Watt Nite Ize mod is excellent for creating a long life light with optimal brightness. Makes a great survival light; have had the batteries in my 2D running on one of these mods for over a year without replacement.
