What Customers Are Saying
The LED upgrade provides a significant improvement in brightness and battery life compared to the original incandescent bulbs. The installation is generally easy, though some users noted the need to leave a small black disc in place during the swap. While a few customers experienced issues with overheating or compatibility, the vast majority were highly satisfied with the performance and value of the LED upgrade.

Would RecommendI bought one of the 55 lumen bulbs for a 20+ year old Mag Lite and it was a good upgrade but as mentioned in other reviews, a bit pricey. I then discovered the 70 lumen bulb and bought three for two Mag Lites and an old Brinkman. All worked well. While I certainly could have bought a Chinese replacement for the same price, I prefer to hang onto my good old USA made flashlights.
Unbelievable & Great technology led better than old bulbs.
Would RecommendI've oldest flashlight in 1950s of my collection as great condition like brand new. I disliked old bulb isn't bright enough so I brought new led bulb to fit in it and so brighter. Love that led technology.

Led flashlight blub
Purchased one before really liked how bright and white light it was. This one is just as good. Use in 2 D cell military flashlight, really great. Will buy more in future.
Didn't work
Would Not RecommendThe package says it fits most D & C cell flashlights but it didn't fit mine. There's no way to take it out of the packaging without tearing up the cardboard so I couldn't return it. I'm out $16.00 and still need a bulb. It may work if it fits your flashlight. I've got one to sell cheap, no packaging.
amazing little light
Would RecommendMy head set now lasts hours with a single aaa battery.
A lot brighter!
Would RecommendI bought one of these to try in an old 9.6v Makita rechargeable flashlight. This flashlight normally uses a regular incandescent flashlight bulb but Lowe's didn't have that particular bulb in stock. They had enough other brands, shapes, sizes, wattage, voltage, lumens, & candle power to make an electrical engineer scratch his head and all I needed was a bulb for my grandfather's flashlight. The package stated this bulb would fit most C & D cell flashlights as a replacement or as an upgrade. I f...
Burned in less than 10 minutes, poor focus
Would Not RecommendI was optimistic about this L.E.D. "UPGRADE" when my Ryobi One+ rechargeable flashlight bulb burnt out after years of use. This LED bulb is the same style and wattage. It briefly provided a whiter, somewhat brighter light, but the light projected in two distinct, concentric rings vs. a broader beam. I pointed it at a cabinet wall and briefly appreciated the brighter reflected light until it quickly burnt out. Very disappointed in this LED.
Flashlite repair
Would RecommendWorked great on my old flashlight that they don't make bulbs for anymore.
This is the best product I have ever bought.
Would RecommendAfter changing this bulb I couldn't believe the difference . I use it all the time.
5 stars but with an explanation...
Would RecommendYou can get a pretty good new LED flashlight for what this cost but it does work well for me. If your light has an adjustable focus beam it will likely work OK. If not, the quality of the light beam may not be as expected, if your reflector was designed for a regular bulb. I did the math and this bulb roughly doubles the lumen output vs a regular bulb in a 2 D cell light. The only reason I bought this instead of investing in a new light was because the light was a gift from my now decease...
Met my expectation
Would RecommendEasy install. Lit up way better than regular.

I installed the light bulb just a few weeks ago, but it seems to do the job nicely.

Does not work for every flashlight
Would RecommendIt does not work with lantern flashlights that take the 6-volt big square batteries. For these batteries, the center terminal is the negative terminal and this bulb requires it to be the positive terminal. This arrangement works for C-cell and D-cell flashlights. Fortunately, I had a 2-D-cell flashlight, so I used it for that one.
Bright light, too expensive
Would RecommendSatisfied with the output from the bulb, however at $13 I'm hoping it lasts forever. Almost could've bought a new light for that.

Not bad little product, some of the reviews had me worried but not hard at all to install just be gentile. Would have given it 5 starts if it was a lot brighter. I guess I could have got the other bulb but a new maglight mini that is LED has a brighter bulb and only 5-8 bucks more than the more expensive bulb with shipping. I think this is a Colorado Company which is why I bought the product. Thanks :-)

Led conversion
Would RecommendPut this in a 3 cell mag light BIG difference! Would recommend.
Well Worth the Money
Would RecommendThis bulb is small, but is bright enough to use as a spotlight. Amazing
