Gee... without doing a close comparison, it appears that you would do equally well with NiMH D cells. I never heard of 26550 cells before, and don't know where they are sold.
Looking at the wire leads on the board in the OP's review, I wonder how the tint would be if the red led positive was jumpered to the white leds positive. Do you guys think having the red led lit with the white ones would make the lower levels a significantly warmer tint? I remember reading about an led light bulb that used that trick, they added a red led to change the tint or improve CRI.
Thanks for the detailed review. I bought three of them for emergencies. Amazon had a good price. Great lanterns. I especially like the smooth diffusion of light & the extra hanging options.
BTW, there is a Super Siege available: http://www.streamlight.com/en-us/product/product.html?pid=341.
You know, that's an interesting question and I have no idea. I'm guessing it might make it somewhat warmer, but I don't know if the red mixing with the fairly high kelvin white (at least of the version I have) would make for a warmer white color instead of still a pretty cool white with a weird red twinge. I don't know though. I wish I could turn the red on at the same time and see if the results are similar or different to my mod with the shaving cap diffuser. In my experience the red light emitted is visible, but doesn't light things up in the environment very much if that makes sense so I don't know if it would change the overall white light color/temp very much at least as it is now with the amount of light emitted in the red mode.
That Super Siege is awesome, but unless you have a generator you can't charge it if you need it for days. I don't think it charges via usb either (maybe I'm wrong). That means it might be hard to use a power bank or something. Maybe there is an adapter that would let you use a usb power bank though? I don't know.
I hope they keep making lanterns and maybe we'll see more versions in the future with removable and/or rechargeable cells.
