Multiple AA lights vs C ?
I haven't had any C or D cell lights since I was a kid but I also don't have any 6 or 8 AA cell lights.

What is the advantage of 6 AA cells vs 2 C cells. Is it just to hit the "magic" 3.6 V number that the emitter requires without a boost driver?

I have a 3d mag and use Kd's  3aa - d converters. Works great on eneloops. I also have 2aa - c converters. I don't have any c flashlights and would not buy any more c or d lights.

Is that just to eliminate having to buy a different battery type otherwise it seems easier to drop in 2 batteries rather than 6.

Also, with the battery converters you have is it wired so that it keeps the voltage the same as it would be with 2 C cells (3v)? Thanks!

yeah 3v x 3 = 9 v  and I'm using a fusion drop in.  I have a few other things I use converters for so saves me having to buy d batteries

I think that many consider 3xC or 3XD as too bulky nowadays. Also the C- and D-cell format is not getting much love from the budget manufacturers. I own a 3C and a 3D now (both with XR-E), which are kind of budget (sub 20€ range) but the overall output/efficiency is not as high as latest technologies on AA or LiIon lights.

correction. My 3aa- d adapters are 4.5v each(or bit less depending on the charge). I am using 2 adapters with a dummy battery.

What sort of current draw? I found those 3AA-D adaptors from KD useless for 4+amps. Problem is, the better multi-AA holders with low resistance are ridiculously expensive. Some enterprising Chinese manufacturer could sell quite a lot of those at a decent price.

Fortunately the Fusion36 dropin doesn't need anything like those currents. From memory it draws about 1.8A with 6 cells. It works best with 4 cells or more. With a shortened tail spring and a bit of plastic pipe you can get 4 C cells into a 3D Mag.

 

For me, 3D is the upper limit for useful size. Beyond that, the lights are more luggable than portable.

 

The numbers from my light tests are always to be found here.

Only about 0.7 A but batteries are not fully charged. I prefer using 2 18650's but it does produce a lot of light with 6 eneloops. A 2d would be my preferred host for this set up. But mine was stolen and its too expensive here to replace. I do like the "club' factor of the 3d. Doesn't really get any use when I have 50+ others to choose from.
