Bulbs for 3 x IMR16340 in 2C?

[ElectronGuru]

Crazy idea #47. Take the old 3x C123A in a 2C Mag configuration and pump it up with AWs new IMR chemistry. Keeping the configuration simple (no resistance mods, double clicking, soft start etc), is there an ideal bulb for a Mag host, powered by three IMR16340?

WA 1185 - potted (if you can find them) or in a bi-pin adapter.

Edit: I guess I should add... if your definition of "ideal" is closer to "brightest" than "longest running".

 

[ElectronGuru]

Yes, should have said. This is not about any practical result, just "fun and wow". A few minutes of scorching output from an unnaturally light package is what I'm after!

You know... It doesn't have to be a mag. If you can find a used g3 and a FM G4 D26 sunlight, it's pretty much all plug and play. You can even adjust the bulb height for more focus.:devil:

A WA 1331 is nice and white on 3x16340 :thumbsup:.

Better than that, I was about to sell my 9P (done with its LED duties)

In the finest tradition of CFP, I now have TWO bipin adaptors en route, one for the Mag and one for the SF. Both will take the same batteries and bulbs, so the only performance differences will be reflector size/design and internal resistance(s).

The 1331 appears to be one amazing bulb, similar output at nearly half the amps:

Balancing everything, I expect the ideal configs will end up being:

1) 3C Mag + 3x IMR 26500 + WA 1185

2) 9P + 3x IMR 16340 + WA 1331

Can't wait to get there. Thanks! :twothumbs

Shipments are trickling in, here's what I have so far

 

[bxstylez]

get a WA1164 bulb.... run it with 3x IMR16340's for about 4-5 minutes total runtime

WAY brighter than a WA1185 (~1700-2000 lumens)

.

 

[ElectronGuru]

Thanks for the inspiration. I kind of ran with it...

I'm SO happy with the 1331 as a lower amp three cell replacement of the 1185, is there a two cell equivalent to replace the 1111? (1274?)

 

[lctorana]

Shouldn't a 1111 work?

After all, FiveMega sells the 2x18500 Prince (I have one) to use 2 protected 18500's with a 1111, and IMR16340 cells wouldn't have any more voltage than these, surely?

I didn't feel comfortable running an 1111 on a pair of 18500 LiCo cells. Even if the voltage sags considerably under load, the current draw would probably still exceed 2C.

I do really like that 2x18500 Prince host though - especially the quick change to the turbo head. So, I've been using 3x IMR16340s and an 1185.

I don't have any IMR18500s yet, and haven't seen any posts of anyone trying an 1111 with a pair of them either. Maybe that would be the ideal combo for the 2x18500 Prince?

I do run the 2 x protrected 18500 with 1111 in my Prince, and am very happy with it.
As for the IMR18500, you'll find recent posts by ElectronGuru who found that the result was We're talking about changing to the 1274, but the jury is out on lumens and colour temperature.

EG post was about a poof on IMR Cs fresh off of the charger.

I run the 1111 in a FM D26 on IRM18650s and never a poof.

Sorry for the confusion, a few clarifications (so many ifications, so little time)


Big IMRs, to much voltage
The 1111 poof is the C sized IMR: 26500. These cells push ridiculous amps and are rewriting the rules on voltage sag.


Small IMRs, to little runtime
My question for post 10 is about low amperage for a particular cell config. 1111's run well on 16340's, but for not long enough. This is what the 1274's may solve. To put it into math lingo:

1185 (3cell high amp) is to 1331 (3cell low amp)
as 1111 (2cell high amp) is to ????(2cell low amp)​

I'm actually hoping the 1166 will solve the poof off fresh 26500 problem I'm having with 1185's.

So, I've been using 3x IMR16340s and an 1185.

Thats a good config, the 1331 off the same cells is even better.

I've never had any luck substituting a 1331 for an 1185.

Before I sacrifice another bulb, can the 1331 handle three fresh IMR16340s without a soft start?

 

[ElectronGuru]

Yes, three imr 16340's loaded in a 9p, pushing a 1331 = :twothumbs.

I've blown a pile of bulbs the last few weeks, non have been off these cells - they have to much sag. See the Surefire31 configuration in the link above for my full review.
