Not from new bulbs, nope...
Batteries, but I'm posting this here (in the incan forum) as I'm just brainstorming some new possibilities and the discussion excitement that can be fired up as a result of this is more related to what incan possibilities there are as a result of the new batteries, rather than the new cell itself. (I think)
Originally, AW posted some charts and graphs about his new cells in LuxLuthors safe chemistry shootout here:

And then I was reading this thread:

Mark@LF spilled the beans about an RCR123 size LiMN chemistry cell. Sounds like AW might have this in the works, I am very curious as to whether there are any MORE sizes in the works besides the 18650 and RCR123 that have already been "leaked." I may just have to contact AW and see if he would be willing to share some more information on what other sizes we can expect....
This could really put some serious leverage back on the incan side for awhile. As many of you may know, LiMn is the chemistry found in "safe" chemistry li-ion cells in many popular new power tools. They are currently being manufactured by a number of companies, Molicel, Sanyo, and Sony, and likely others that have yet to be identified. 18650s and 26650 sizes are pretty common in power tools and not too hard to get ahold of. Sounds like AW will be bringing his own brand to the table, and based on pictures he has already posted, it appears that he is shooting for a complete consumer style cell with button top and all.
For those who don't already know, a LiMN secondary cell is basically a 3.7V rechargeable cell, just like a "normal" cobalt chemistry cell, but who's chemistry is more stable, and more tolerant of abuse, and of lower internal resistance. They charge up to ~4.10-4.20V (depending on specific flavor of cell type) and can pretty much always be charged on a conventional li-ion single or multi-slot loose cell charger provided it is designed for 3.7V li-ion cells. I'm assuming that the specific chemistry AW will be using would follow this same charging guideline (just guessing here)...
Anyways, these cells can handle serious current output. Usually to the tune of 10C or greater, but tend to have about 30% less energy density compared with liCo cells (cobalt chemistry cells). What this means is that, IN THEORY, we could be pushing many very high powered bulbs, with a handful of very small cells. Yes runtime will be short, but this opens up some new design possibilities worth looking at...
Here's some of the more obvious, and maybe some less obvious options that come to mind:
----------------------
1xLiMn RCR123
A 1xCR123 "P60"/"D-26" compatible host with any 3.7V incan lamp, (HO-4, EO-4, WE 3.7V, G&P 3.7V, etc etc)
A 1xCR123 LED light, modified to a P7 emitter, direct drive from this RCR123 (safely, and probably as bright as similar 1x18650 mods that people have done)... (yea, I know it's the incan forum, but this cell will break some new ground in this one LED area also, might as well mention it).
----------------------
2xLiMn RCR123:
A 2xCR123 "P60"/"D-26" compatible host, running ANY lamp ordinarily reserved for larger pairs of li-ion cells. That includes the EO-9, P91, FMs 1794 w/D26 bi-pin module.
A 2xCR123 host with "SF M head" (converted, or otherwise), with Z46 bezel, running the HO-M3, EO-M3, or MN11
A 2xCR123 host with SF turbo-head installed, running The MN16, MN20, HO-M3T, EO-M3T, or, possibly even the MN21 (depends), or with the FM bi-pin to MN socket, a WA111, 5761 (maybe), and many other bi-pin bulbs ordinarily ran on 2x larger li-ion cells.
----------------------
3xLiMn RCR123
Want to turn your M3T (or equivalent lego) into an 1185? Here's your chance. Need an FM bi-pin >MN socket.
here's an easy one: HO-M6R in M3T.
----------------------
4xLiMN RCR123
overdrive a 12V G4 base bi-pin lamp that fits in a SF turbo reflector in an FM>Bi-Pin to MN socket. This could be done in a M4 (or equivalent lego) or an M6 (with the 2x18650 adapter, just laod RCR123s in it instead).
----------------------
lets see, things get interesting now....
----------------------
6xLiMn RCR123
1.5D cut-down tri-bored mag, cells in a 3-abreast configuration, wired series, should be able to safely achieve 60W+ modifications. Not sure about specific bulb recomendations, but there are probably a number of 12V long life halogens that would work, may need a soft start or minor regulation.
----------------------
Ok... that's enough brain storming for me now... I don't want to start getting into all the options that could be done with other size cells until I have some confirmation of those cell sizes coming to fruition
Ok- one teaser idea based on cells I have no idea about, a 64458 (or something similar) running on 6 17500s in a tri-bore 2D with regulation. 100+W 2D mags will have some more options open up, even approaching 200W.
If you have any ideas, thoughts, I'd love to hear em
