That's good to know. I guess I won't be doing any resistance mods then...:duh2:The protection circuit on them is set at ~5.5A.

They can, but you lose the ability to store a spare lamp (as the tailcap is filled up). With 3C, you can still fit a spare. 1185s are nice in that they're one of the only bipin bulbs small enough to actually fit in the spare holder of the MagC'sWell, this pretty much fits the bill for my original goal -a Mag85 with more runtime in a more compact host! I had no idea that 3 C cells would fit in a 2D Mag - this sounds perfect.
I don't know but I think that 5761 in the max for 2 AW "c" cells...
also with this set-up you should use a soft starter...
You're a bad influence on people Rich. First you sell me your 6AA -> 2D RoP (my first hotwire) getting me hooked, then I read this thread and decide that I need to build a 2C RoP with AW's "C" Li-Ion cells for better run time and a smaller size. :candle:
Who know what you'll talk me into next.
Then my work here is done. :naughty:
If I have to be pulled into this vortex of pursuit of ever-brighter and better incandescent hotwires, I'm taking everyone I can with me!
Seriously though, if you really want to blame someone, blame LuxLuthor, mdocod, and 2XTrinity just to name a few...they are the truly bad influences! :devil:
A 3C Mag is another alternative, but my main point is you need to watch your full charged voltage (or add some minor resistance).
Thanks LuxLuthor. Now I'm just a little nervous about my config since I'm using AW's C driver which has super low resistance. I put one of these in a 2C Mag w/ 5761 bulb, and it seems twice as bright as when I ran it in a stock Mag config, even with a low resistance mod in the tailcap. I use a WF-139 charger and AW C batteries, and they charge up to about 4.10v. I don't think I've ever had a charge go to anything close to 4.20v. Would this be a pretty safe voltage, or am I still at risk of instaflash? Is there an easy way I can add resistance if I run into problems?
BTW - nice vortex Lux! But that one doesn't even compare with the real one you've helped to create here!

Good to know, thanks. I'm feeling a little better about it, especially with the soft start. One thing's for sure though, this is going to be one white beam!I remember asking AW who said his driver had around 200 milliohms, so I think you will be OK, especially with the soft starter feature, but I honestly have not tried that specific setup to know the total resistance....so I'm pretty sure that will be ok, but not 100% sure.
Thanks 2xTrinity. I guess since the regulated versions aren't ready yet it's good I'm going with the C cells. It sounds like from what you and Lux have said that with the soft start and slight sag of the C cells I should be relatively safe from instaflash. Based on my last Mag85 vs Mag61 shootout, it is going to be very interesting to see how these two new builds - each with an AW driver and C cells - is going to turn out! After seeing the crazy output of my new Mag61 build with the AW driver and C cells, I almost abandoned my Mag85 because it outclassed it by a good margin. In the end though, I would miss the nice tight, beautiful beam of the Mag85, so I had to do the same upgrade to it.
Considering there is no inrush current with a soft starter, I would say as long as you don't charge your cells above 4.15V, you should be fine. And in the cae of the AW C-Cells, which sag more under the load than the Ds, you may be fine up to 4.2.
Yep.Does the Mag61 use a Phillips 5761?
It's become a convention on here to title a light:Does the Mag61 use a Phillips 5761?
I know that...It's become a convention on here to title a light:
"Mag" the bulb number of a light without the leading two digits, ie:
Mag11 -- WA1111
Mag85 -- WA1185
Mag61 -- Philips 5761
Mag623 -- Osram 62623
I know that...
I was just partially confused by Rich's comment because on paper the 5761 doesn't necessarily look like a very good bulb to use with 2 AW's "C" Li-Ion's due to current draw being greater than 5A (the limit of the batteries circuitry) and the fact it goes poof at 7.9V, so I asked to double check. :shrug:
Never! :thinking:So when do you start your Mag61 mod?
