Review: A must have for any old flashlight. - These dorcy led replacement bulbs are a fantastic way to breath new life into your old flashlight! Probably not as high tech or bright as some of the pricer optikns out there, but these are a great equivalent bulb that will most likely still be brighter than any old incandescent style bulb. Like the pure white light and since its led it will make batterys last way longer. Highly recommended cheap upgrade! Works well in 3 cell maglites!
Review: Plug and play LED bulb for old 6V Flashlights - Works in an old fashioned 6V flashlight without modification. Just replace the old bulb and turn it on. It's brighter than non-LED bulbs, but not a lot. It does not turn the flashlight into a super spotlight. Other more expensive products might be brighter. The upside of not being super bright is that it probably uses very little power so the 6V battery should last a long, long time. The only improvement I might suggest is a broader LED beam angle. Almost all of the light is very narrowly focused. One of the purposes of a larger 6V light is to illuminate broader areas. The narrow beam angle defeats this purpose.

### ⭐⭐⭐⭐ Does well in 6V flashlight
*by G***Y on September 12, 2012*

In a 4 D cell flashlight, it throws out very bright beam for good distance. And being somewhere around a 120mA bulb, should be kind to the batteries. Those having problems with this bulb providing enough light are probably using it with 2 or 3 cell flashlight in my opinion. Those commenting that say they have 4 cell flashlights seem generally pretty happy, as am I. My only criticism is that there is a round shadow in the middle of the beam. And the flashlight can no longer focus beam, though it had that ability with krypton bulb. But even if not perfect, for the money it gives a good strong beam of light and batteries should last well. This is just an old flashlight I resurrected for infrequent use. Better than the cheapo plastic LED flashlights where the batteries last longer than the flashlight.... An update. After bit tinkering finally got my flashlight adjusted to do away with the round shadow in middle of beam. Hadnt used the flashlight for so long, I'd forgot some of its secrets. It gives nice strong beam, goes completely across my yard and into woods. Around eighty feet or so. Plenty bright for my needs. Though sure it depends on the particular flashlight and the quality of its reflector, yadda, yadda, yadda.... But if you have a favorite old 6V incandescent flashlight using PR style bulb, I'd say give this a try. The cheap plastic LED flashlights for sure dont hold up and for most part arent repairable. This bulb used in a good incandescent flashlight might. And no vulnerable non-replaceable external LED circuit boards to deal with.
