Right,
Like Joe says, the xenon bulbs tend to be a bit more highly strung. They don't take an awful lot of overdrive. For example, I have driven a 6 cell bulb on 7 cells and it works fine.
MXDan,
The Osram 64625HLX is a 12V bulb that some of us run in highly modded Mag 3D bodies. in fact, all the bulbs I listed can be run in a Mag 3D body. It draws 8.5A and you need high current nimh or nicad to run it. 10-11 of them.
SJackal,
Krypton bulb 5 cell: 82 lumens
Krypton bulb 6 cell: 98 lumens
Krypton bulb 7 cell: 119 lumens
Xenon bulb 5 cell: 106 lumens
Xenon bulb 6 cell: 129 lumens
Xenon bulb 7 cell: 178 lumens
Davide,
Running a 2 cell bulb on 3 cells is very iffy. You are just as likely to blow it as it is to run. I have found that 2-cell K bulbs either blow or last about 10 minutes, but no longer.
Blue,
The overdrive a bulb can handle safely is usually in the under 20% range. Reliability is good there. The overdrive you can actualyl run depends on the bulb specs (what its normal rated life is) and how tough the filament is, and how many bulbs it normally runs on. Higher voltage bulbs give you more safety room to stick an extra cell in.
The "grin" of the projected filament with lensed end bulbs can be moderated by sanding down the lens with some fine to very fine sandpaper or etching it with acid.
