please help on mag bulbs

[davidefromitaly]

someone have measured the differences beetween the output of the various type of mag bulbs?

1) white star
2) white star kripton
3) mag-num star kripton
4) mag-num star xenon

 

[SJACKAL]

I am curious too...

Is White Star is equivalent to common vacumn bulbs?
Is White Star krypton is equivalent to common Krypton bulbs?
Is Magnum Star Kryton a higher quality Krypton?
And Magnum Star Xenon just another Xenon bulb?

 

[Ginseng]

Here you go.

Krypton bulb 3 cell: 34 lumens
Krypton bulb 4 cell: 58 lumens

Xenon bulb 3 cell: 54 lumens
Xenon bulb 4 cell: 85 lumens

Welch Allyn 01160: 327 lumens
Welch Allyn 01185: 817 lumens

Osram 64625HLX: 3,600 lumens

The Whitestar K can be considered a common krypton bulb. The Magnumstar X can be considered a common xenon bulb. Common in this case meaning typical flashlight quality bulbs to distinguish them from specialty bulbs made by Carley, Welch Allyn, Gilway, Philips, Osram etc.

What the heck is a 'Osram 64625HLX'???

I don't think alkaline batts could handle that kind of draw... /ubbthreads/images/graemlins/wink.gif

What about 5 and 6 cells? /ubbthreads/images/graemlins/smile.gif

 

[davidefromitaly]

thank you ginseng

is normal that i have try a magnum kripton 2cell with 3ni-mh cell and it blow immeditely? then i try a white star 2cell and it work and it is very bright!!!!!!!

 

[Blue_Shift]

ginseng,
this is a little OT but, if the Welch Allyn bulb calls for 5 or 9.6 Volts, How much higher can you go without hurting the bulb?

 

[PlayboyJoeShmoe]

One thing to consider.

The Magnum Star Krypton bulb has that stupid focusing lense on the end.

If you like the "grin" more power to ya!

I find overdriving a Whitestar 3 cell bulb with 4 is okay, a 4 cell with 5 safer, and a 5 cell with 6 safer yet.

The Magnum Xenons I would NOT try to overdrive. The ones I have tried in a M*g give an even tighter tight focus, thusly seeming brighter. Those bulbs work QUITE well in lights like TEC 40, Rayovac Industrial, and some others with textured reflectors.

How to use that Osram thing in maglite?
and what about wa01185? I really want to make my maglite that 3600 lumen bright..

 

[Ginseng]

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.

You can run a PR-base potted WA01185 in a Mag 3D using three of Elektrolumens V2 3-D adapters and 9 nimh AA cells. To run the Osram bulbs, do a quick search on "Aurora", "Phoenix" and "Mule"

Thank you Ginseng,

So if I am running 9 volts (3XCR123) on my Mag 5 cell bulb, overdriving it by 1 cell, what would be the lumens roughly?

The WA1185 sounds interesting!

 

[bwaites]

Sjackal,

Roughly---150%-175% of design Lumens--

There is a formula to calculate that. Let me see if I can find the graphs. For some reason they won't copy and paste, but here is the thread.

I don't know how to shorten them guys, so if one of the moderators would like to, please feel free.

[SJACKAL]

Thanx Bill, also, you have PM.

 

[Ginseng]

SJackal,

Just keep in mind voltage depression. The current demand of the Mag bulbs are not very high (well under 1A) so it's not really an issue, but at higher demands, the lithium cells depress heavily and you may not be getting all the volts you might think you should be getting.

For the lumens rerating, try this. It is the oft-quoted Welch Allyn halogen rerating formula.

Lumen(rerated) = Lumen(spec) * (Voltage(rerated)/(Voltage(spec))^3.5
