4v and halogen`s good! I have a 5v halogen in my 4D maglite that works quite well.
@Snakebite yeah, I`m a little bit the same too, I`m tired of the Spam attacks you get (usually ending in .XYZ) when giving some places your email addy.
I have a halogen in my 2D also, but I use 8A LSD batts so it`s not so bad, I`m with you on the brightness, I kinda expected a bit more out of it too, though I do have some Xenon bulbs on order for it that I`d never seen before called Fish eye lens, and it says:
Bulb type - 2 cell
- - Average Peak beam candlepower = 19,200
- - Average Lumens = 40.6
- - Up to 100% brighter than previous Magnum Star Xenon bulbs
So hopefully if these are any good I may try and get some 3 cell versions.
I think 4v @ 1A on alkaleaks may not peform much better than Krypton bulbe of 3.6V as the current is high and the headroom before the batteries start dropping is a lot smaller that is why bulbs are rated at 1.2v/cell instead of 1.5v/cell.
I`v got D cell maglites in 2,3,4,5 and 6. Every now and again I like to treat them to something new/better and this month was my 3D
I have one of those magnumstar bulbs for 3 cell on the way also since I`v not had much luck getting anything else.
