is it do-able?
wa01185 bulb, 9.6v @3.15a

considering i'll be using (8) sanyo eneloops aa nimh's, which tests show, can handle high amp draws

 

[EvilLithiumMan]

At 3+ amps, the eneloops will only be at 1.15V, giving a total of 9.2 volts. Seeing as the "typical" Mag85 uses nine cells to deliver 10.8 volts under load, I would expect the eight cell attempt to be somewhat yellowish. Probably still plenty bright, just not as sastisfying. Also, I don't know what the eneloop's diameter is, you may need the body bored out to accept them. Have fun!

 

[Trashman]

It's not going to be as bright as you'd want. I think an FM 7.2v axial bulb (from Fivemega) is the brightest bulb on 8 cells. If you do get the axial bulb, just remember to let the cells rest before using the light.

the eneloops definitely fit in a stock mag as i'm using 7aa eneloop's in modamag's 8aa->2d, powering the rop hi-bulb
definitely very white and bright!

the more i think about it, the mag85 will just be slightly brighter than the rop?
would anyone see a difference? :huh:

I have this project setting on my desk right now, the 2D, KIU/hotdriver, 9x gp2000, SMO reflector, borofloat and some wa1185's. Here is a link to it.
With a tri-bore, 9X 4/5 A's, usually the gp2000, two brands from cheapbatterypacks available, they are said to give about 2.2Ah without a voltage sag, as a matter of one report they hold the higher off the charger voltage fairly well.

Great! I have a couple of his 8AA2D holders, but no unused bored Mags available. Ordered a few packs of Eneloops and will put those holders to work.

The FM axial bulb may be bright with 8AA but at 3.2 hours rerated life the risk of instaflash is way too high (especially with Eneloops) unless using a regulator.

WOW!

the wa1164 bulb looks very promising!
i'll have to look for the bulb and try it out

i found some beamshots over at:

(i'm not sure if linking to another forum is permitted here - if so, mods pls remove)

the site above shows the fivemega 1500L using the wa1164 bulb

[bxstylez]

does anyone know where i can find a wa01164 bulb, either potted or bi-pin?


thanks!

 

[missionaryman]

yeah me too - I'd definitely want to try an 1164, are they in the thread for unpopular WA bulbs?

 

[bfg9000]

FM still has potted ones here.

Or Litho123 will be ordering some bipins on Jan 8th in the unpopular groupbuy.

HUH? Take Notice, bfg9000, Thanks. Thanks, bxstylez, for starting this thread. I have missed everything said about the 1164 until this thread. I got makings for another hotwire and I got over the 1185 phase before I finished my first M85. Popular bulb but it can be beat.

Looks like my equations and yours are the same for re-rating as I came up with those numbers too and that got me going! I got 9x GP2000 that are reported to be 2.2 Ah. That is 31 minutes of light. So I will put those on top of an AWR hot driver. I have a multi-bored 2D to work with this. When AW’s C lithiums are released, on a hot driver I can see 3D M64 with 6.6 Ah. That figures to 93 minutes of more than 1000 torch-lumens. Those are better parameters than I see for a M85 in 3D.

Thanks again, we all learn so much from each other. I am off to buy more stuff for this project.

I used the standard CPF formulas provided courtesy of Lurveleven. The 1164 is really nice for 1990 and older Mag 2Ds because those do not need boring to hold 8AA (and being anodized inside do not tear up battery wrappers like bored Mags) so it is an extremely simple mod. If the 8AA can deliver 2000mAh at 4.25A, that is ~28 minutes, which is not bad for >Mag85 brightness in a 2D with cheap cells!

Aren't AW's cells 3200-3300mAh? In series, 3 cells should provide 3200-3300mAh at 11.1-12.6v, and AWR's hotdriver is a linear regulator that converts the excess to heat. If you run 2 stacks of 2 cells, that could provide 6.6Ah but the hotdriver can't boost 7.4-8.4v to 9.6v... BTW JimmyM's Li-Ion D cells also look interesting at 5000-5400mAh...

I have a 2D mag w/ 8xAA and 1185 bulb, but I built my own Kiu-type socket so there is a bit less resistance there. I'm plenty happy with the output- bright, hot, white.

In the past almost always when someone mentioned a 2D mag the standard answer was to use 7xAA and the 1274 bulb. In some ways I wish I had gone this direction.

Thanks, that page is a geat source to print or save on disc. All the equations in one place. I do not have to search or extract them that way.

AWR put the equations into this hot rater:

http://homepage.mac.com/rouses/flash/hotrater.xls

They are the equations that can be found on the walamp.com site of Welch Allyn. You can take the standard parameters of a bulb not on the sheet,e.g. 1164, phillips 5761, and drop them into the blue design parameter boxes and you got a new bulb in it. This is a great toy to keep feeding voltage values to see what direct drive vs. drivers can yield as it instantly calculates all the figures you want. Cut, paste and save, my personal copy grows every time someone posts about a combination that intrests me and I add it.
