Additional Information


The upgrade kit arrived today. In less than 5 minutes, I had removed the original incandescent bulb from my three-D-cell Mag-LIte, and replaced it with the Litt Industries LED bulb. After disassembling the head of the flashlight, all I had to do was unscrew the retainer ring on the original light bulb and then put the new LED bulb in its place. I was able to use the original retainer ring on my 18-year-old Mag-Lite. The upgrade kit also had a new polycarbonate lens, which I used to replace the old plastic lens. The difference in brightness is amazing. You can still adjust the beam by turning the flashlight's head--exactly as before. I had upgraded a Mag-Lite mini-flashlight yeas before with an LED bulb, so I wanted to see how a full-size Mag-Lite would perform. I am very happy with this conversion, as there were none of the compatibility issues associated with other companies' offerings. This upgrade is well worth the price--which, by the way, is about $30 cheaper on Amazon than on eBay!

I gave it 5 stars for now. See actual photos. These are from about 5 feet. This is in a 3 D-Cell Maglight with 4 year old bulb and 18 month old batteries. Here is what I see. When set to a spot, which is where I use it most of the time, the center spot is a little brighter and overall it seems to cast more light to the outside edges. When zoomed out, the larger center area is slightly brighter but the very center is completely void of light and the edges are dimmer. I have not put the glass lens on yet as current lens is fine but is a plus on this buy.

Nice light update for your mag light, but. Install was easy, the light is definitely brighter, but it flickers a little when you tighten or widen the light. Plus, for the price, just buy a new version of the mag light for a few bucks more, this way there is no problems. That's what i did.

LED circuit board is not even in the housing 100% and what a shock. Does not work. Tried to contact the company that makes it. No response. The lens is nice tho. No complaints about the lens, however I also didn’t try smashing it with a hammer.

Update - they still have not responded (over two weeks) to their email address listed on a card that gets sent with led upgrade and lens.

I have only had this LED replacement bulb for my 3 D-cell Maglite for a short time, but so far the lighting is much better than the original bulb type. The original bulb (and replacement incandescent bulb) had burned out. I started to order a similar bulb, but decided it was worth it to try the LED replacement. I am not equipped to measure lumens so I cannot say for sure that it is the 350 advertised lumens, but the bulb provides at least 3-4 times better lighting than the original incandescent bulbs. Time will tell, but for now, this is a significant improvement in the lighting.

Good product
.. enhance my Mag light ! The differences were amazing ... the advertising was an understatement ! Will order again

I shop at goodwill at least once a week, I found my first 3 cell mag-lite and purchased it.
I got on the amazon web site and looked up LED upgrade for this old mag-lite, this LITT upgrade kit was what i needed it came with a replacement lens to replace the old scratched up lens, it was good as new and much brighter light. So when I found an old 2 cell mag-lite I upgraded it with a kit for the 2 cell flash light.
I am very pleased with the results these kits provided.

Easy to install, very bright, no comparison to the original equipment bulb and lens. I plan on retrofitting more of my Mag lights!
