Nite Ize High Power LED Upgrade - LED Light Bulb for C and D Cell Flashlights - 74 Lumen Replacement Upgrade Bulb for Soft White Light - White

This was a great way to wake up some old flashlights. After using a nice bright AA LED flashlight, there's little desire to lug around a clunky 3-D cell incandescent light. I had a box of nice old D-cell lights gathering dust, and I'm one who hates to throw away good things, so I decided to try these. These cost more than the flashlights did on sale, but at least I didn't have to throw them away. These worked really well in the old stainless Garrity flashlights I had, and made them much brighter more usable than before. These aren't flashlights I use every day, but some that I keep in the garage and other places I need an occasional light.Just be aware that the light shines from these bulbs in a different way than in an incandescent bulb. The little led sits up high in the middle of a small "platform" so therefore, it doesn't shine down around the base as it would in an incandescent bulb. This could make a big dead spot in the middle of the beam, depending on the position of the bulb and shape of the reflector.UPDATE: I wanted to use one of these upgrade LEDs to upgrade a really neat old Bakelite explosion-proof flashlight I obtained. It worked OK, but the LED produced a large dead spot, which I call a "donut" hole. It also produced several very annoying rings. I tried putting pieces of clear tubing around the bulb, but that didn't work. Finally, since the tiny LED is on top of a small platform, I thought about trying to lower the LED bulb in relation to the reflector. What I finally came up with was using a small copper washer that was just small enough to fit into the bulb holder. Of course the hole in the washer was much too small to use, so I had to carefully file out the center of the washer. Yea, this was tedious, but the result of putting a 0.05" washer in-between the bulb and the reflector was amazing. The donut hole and the rings were completely gone and resulting pattern was really nice. It now produces a fairly distinct bright spot that projects really well. There is virtually no "corona" or transition to the flood or "spill-over" light. But the flood light is huge and just bright enough to illuminate a large area around you as you walk. My little Streamlight is still brighter, but it can't come close to lighting up the area this light does. I literally opens up a whole new world as you walk through trees and brush at night. I did try adding another washer, but this did not make it any better.I decided to try this on my inexpensive Garrity lights and had the same success. The Garrity lights have a bigger reflector, so the bright spot as well as the flood light were also bigger. This fix was really simple, I just put an 3/32" thick O-ring in-between the bulb and the reflector and placed another O-ring in-between the screw on head and the flashlight body, so as not to stress the reflector.I know this is a lot of rigmarole to go through for an upgrade, but if you like to tinker you might see if you can do the same thing if you're having the same issues. Hope this helps.

I had an old industrial Bright Star hard yellow and black hard shell flashlight that I liked and didn't want to throw out. It was a 2D flashlight with an incandescent bulb and maybe 10 lumens, I made a mistake by not taking it apart and bought an old Dorcy screw in replacement bulb and upon taking it apart it had the flange style bulb.After a little fiddling ,it fit in without any modification.I am glad I got this 74 lumen instead of the other 55 lumen they make in a similar package.You get spoiled after using high lumen leds. It has a nice throw at close range and good a little further away to suit its worklight purpose. I got some D cell Panasonic Platinum Batteries that are great from Amazon and are long lasting. The light has a flashlight flood with a donur ring small center much like the original bulb but brighter. After all, it's a very good worklight and not a long distance throw. Today you can buy some flashlights for the price of the bulbm but if you have a Maglight or a favoright durable housing light, then it is well worth the cost. Cheaper lights that work i donate to the Salvation Army Store I recommend this to anyone. It is bright enough that you can't stare into the lens when on.

If you're wondering like I was whether to upgrade with a product like this, or buy a whole new Maglite, here's a comparison of the original Maglite 3D (incandescent bulb), a Maglite 3D with this product (Nite Ize LED Upgrade Bulb C/D High Power), and finally Maglite's own LED 3D flashlight (LED bulb as stock). This comparison was done with a new pack of D cell batteries for all flashlights. Note that due to my lack of photography skills, the difference in brightness doesn't really come through in the photos I've uploaded, so you'll have to trust my assessment below which also included ceiling bounce tests (shine the light at a white ceiling and assess the overall brightness of the room).The original incandescent vs. the Nite Ize High Power LED Upgrade: I would estimate that the LED upgrade is about 50% brighter than the original incandescent. As is obvious from the photos, it's also significantly whiter and clearer than the incandescent.Nite Ize High Power LED Upgrade vs. Maglite LED 3D: The stock Maglite LED light is about 50% brighter than the Nite Ize LED. Worth noting, and rather obvious from the photos, is that the stock Maglite LED not only has a larger and brighter spot, but also a nice bright flood even when the spot is highly focused as it is in the photos - so bright it actually overpowers any flood light from the other two lights.So, does it make more sense to upgrade an old Maglite, or buy a new LED one?First off, if brightness is what you want, it must be noted that these days you can get equivalent or greater brightness from even single AA LED flashlights - and with many of them, variable brightness levels, so you can go from very dim for close-up tasks, to blinding bright for distance viewing. If you need extra long-run times, I guess the Maglites are still a good option, but I think the real advantage is that a 3 or 4 D cell flashlight can also make a decent club, and I assume that's why you're interested in having one (though I'd still recommend a good pocketable AA LED light as well).If you already have an old Maglite and you're thinking of an upgrade, the problem with the Nite Ize LED is that it's not significantly cheaper than the sale price of the Maglite LED 3D and, additionally, not as bright. I think the price of these Nite Ize upgrade LEDs should be more in the 5 to 7 dollar range. $5 would make it a no-brainer. As it is, though, if you're going to spend the current asking price, you should first ask what the condition is of the old Maglite you're upgrading (i.e. is the lens all scratched up?) and whether it wouldn't be worth it to spend $10-$15 more for a new Maglite with LED, which will be brighter and better than an old Maglite with this upgrade.Either way, you should definitely move on from those incandescent bulbs. The brightness and durability of a *good* LED flashlight is a world of difference from old incandescent ones.

Used this bulb to upgrade my old 2 cell Mag light flashlight just before Hurricane Irma hit Florida. It was easy to install and bulb works great. It is several times brighter then the old one. We lost power for 7 days and this was my go to flashlight. I never had to change the batteries due to the LED low power usage. The only issue I have noted is there is a black spot in the center of the light beam when you un-focus the beam to increase the beam area. I prefer to beam more focused so this is not an issue from me.
