LudoPam Upgrade LED Bulb White 3W DC 4-12V LED Flashlight Bulb Replacement Part Compatible for MagLite Flashlights Torch 3-6 Cell C&D

Major upgrade to my 2-cell Maglite. The beam is brighter and shines farther than expected.

No, this isn't as bright as some of the "tactual" LED flashlights that are sold, but it has resurrected my favorite old Maglight. Some have complained about the "halo" or doughnut effect of the light and when I try to spread the light that does happen... so I just don't try to go wide beam. I can't speak to longevity or energy consumption as I have only used the bulb for a couple of days, but as for the light it puts out, it is a great improvement. The standard bulb sends out a pale yellow light that could reach a large tree about 60' behind our house, but you couldn't make out much detail. The "LudoPam High Power LED Upgrade Bulb 3W DC 4-12V" in my 3 cell Maglight sends out a white light that not only shows the tree in great detail, but also can illuminate the little meadow and even reach the top of the 100' tall tree. This helps me see if there are any predators around before I turn my Chihuahua loose to do her business.

This bulb fit right in my old Maglite flashlight. This LED is far better than the original bulb and much brighter. You must consider that with only 2 batteries, this restricts the bulb to 3 volts. The result is more light and whiter light, but no where near the output of the more powerful flashlights with 3 batteries and 4.5 volts to drive the bigger LED bulb. This is the reason why you see the different bulbs advertised with the cell numbers highlighted and why people complain about expecting brighter light output. This bulb is still so much better than the original, it is worth every penny to upgrade.

Easy to install, replacement for an old incandescent bulb in a 4 D cell maglite. The results were dramatic. Much brighter and on par with a lot of modern led flashlights. Ordered the the other prominent brand and tried in a 3 D cell results were not quite as good. I believe LuduPam is the better LED for ten bucks it’s hard to beat. I can’t speak to longevity yet but I will update this review if I have any issues.

I installed it into a 6 volt flashlight because the incandescent bulbs did not last long with the 6 volt lead-acid battery I was using in it. If I turned the flashlight on immediately after taking if off the charger, the incandescent bulb would burn out. This bulb does not burn out and puts out a lot of light. Note that since the flashlight was not designed for this type of bulb, there is a dark spot in the center of the beam.

Ordered 2. Beautifully made. Neither one worked in either of two flashlights. I could not believe it and tried to modify contacts so there was no question about the bulb fit. Because they did not work still, I wondered if there was a polarity problem (diodes, by design, let current flow in only one direction). I finally connected them to wires connected to the battery pack and checked current in both directions. I cannot explain what happened, but they both worked with reversed polarity. One flashlight permitted reversing the batteries with good contacts, and the other only questionable contacts. The one with reversed batteries (putting the + at the - end where marked in the flashlight), works great now. It is a great bulb with intense light output. The other one, with questionable contacts, did not work, even when I tried to stuff a wire between the contact and the battery pole. I then reversed the batteries back to the way they were intended to be placed, and the light bulb worked perfectly. It produces great light that is well focused. I cannot explain this phenomenon. Clearly diodes, unlike filament lights, are very polarity-dependent, but this outcome suggests that there may be some breakdown in the farication or testing process (quality control) allowing them to leave the plant in this condition. If they work great right out of the box they should be 5 stars. If you have to do as I did and possibly not have the same happy ending, they may be worth 1 star. It is unfortunately a toss-up at this point.

This is a great upgrade! I have an old (from the early 90's I think) Maglite that takes D Cell batteries. It has been a workhorse and did the job. However, some newer LED flashights were making this thing look like a dinosaur.It did not put out as much light and used more battery power. The LED bulb makes this a lot brighter. Plus, it uses less power which means the batteries will last longer.This extends the useful life of my Maglite a lot - glad to keep it on hand! Just wish it were rechargeable.

When I 1st received these conversion kits, I could not get the bulb to fit the Maglite, as the new LED bulb diameter was too large to fit through the Maglite retention ring. This problem was noted by other reviewers and I did not see a solution to it. Eventually I figured out there are 2 different sizes of bulb retention rings for the Maglites. Both retention rings have the same threads so they will fit any 2, 3 or 4 cell Maglite, but the ID of the opening for the bulb to pass through is different. These different retention rings can be found in 2, 3 and 4 cell Maglites. The LudoPam LED bulbs only fit through the Maglite retention ring with the full ID bulb opening and they do not fit through the Maglite retention rings with the more restricted ID bulb opening. I was unable to determine which Maglites use the larger and smaller bulb ID retention rings. It seems the bulb vendor should make this more clear since they advertise their bulbs work in all Maglites. I ended up using a Dremel to ream out the bulb-end ID of the retention ring so the new LED bulb would fit correctly. Once installed, they work great! Much brighter than the old Maglite incandescent bulbs.
