TRLIFE Maglight LED Bulb, Maglight Bulb Replacement for 3-16 C&D Cells Flashlight, 3W Maglight LED Converter Replacement Bulbs for 4V 5V 6V 12V 18V Maglight Flashlight(2 Pack)

Have some old mag lights and wanted to modernize them with a led light bulb. They work great and now I have a very bright light. Since it is LED the batteries should last a lot longer.

Bought these to up grade a flashlight that was given to me, perfect upgrade, low cost, super bright bulbs with a hint of dull yellow

Jolly good! Quick install and nice brightness - considerably brighter than the original factory bulb.

Back in the 1980s and 1990s, those big skull basher Maglites were quite popular. Seems like every household had at least one tucked away, and they were common sights on the belts of police and security guards. A flashlight that could double as a melee weapon certainly had its appeal, but flashlight technology has come a long way over the decades. So much so that those old Maglites had lost their sheen.That's where these LED conversion kits come into play. For (as of this writing) $9 you can get one and for $16 you can snag two. I decided to grab the two pack, not really sure what to expect from these. I tested them on my 3 cell Maglite gifted to me so many holiday seasons ago. The other was my Dad's 4 cell Maglite which I'm sure is at least a quarter century old as of this writing.My initial impressions are very positive. For starters, the installation is about as simple as can be, it takes mere minutes. As for the end result, it breathes new life into these old behemoths. I will agree with some other reviewers, who noted that the final result is not as bright as a brand new LED Maglite, of which I own a couple myself. Still, you have to remember that's comparing a brand new flashlight to one likely many years old. That said, the LED conversion is much brighter than the old incandescent bulbs, honestly more so than I expected. There was a peculiar greenish tint to the lights as well, both mine and my Dad's, though it does not affect using the light. Its not like someone casting a color filter over your flashlight or anything that strong, just a very minor hint of a pale green.Overall, I'm pleased. I hated the idea of getting rid of my old Maglite, but with so many better options, I just never used it anymore. That's definitely going to change. I plan on keeping it under the bed in case of power outages or other late night curiosities. For the record, I held onto the old bulbs from both my and my Dad's Maglites just in case. Initial impressions are positive, but I have no idea how these lights will hold up in the long run. Still, giving those old Maglite titans a new lease on life is worth a $9 LED in my humble opinion.

Completely transformed my old Mag flashlight and kept it from feeding my recycle bin. These bulbs are fantastic and beautifully update the antiquated Mag light to a flashlight that’s bright and usable.

Fits easily and brings my old 3 x D cell Maglite back to life. So much brighter with LED than incandescent. No idea of longevity but very happy so far. Recommended.

Ordered to replace the incandescent bulb in my Mag light. Replacement of the original bulb was easy, new LED light works perfectly.

A lot brighter than the old incandescent bulb originally installed in my 4 D-Cell diving flashlight.I could have given a 5 star if there is an instruction to try to reverse the orientation of the battery if the light won’t turn on.Apparently this LED bulb has a negative (-) bottom polarity. But most flashlights , like the one I have is designed for positive (+) bottom bulb. So, this bulb did not turned ON when I first installed it (I almost returned it). Then I thought of reversing the position of all the batteries, lo and behold, a bright light flashed on my face. Bottomline … satisfied!Hope it will work with your application as well.
