*latest update* My Amilite Neo T3 now looks like a Neo T5, since adding the T5 body and 2x stage tailcap. Also, my T3 is the earlier type, I believe, as it has a smooth reflector instead of the stippled/orange-peel surface type. Here is the only image that I have of it as it appears, now:
...it's on the far right. The image is for a tint comparison and all lights are each on their individual low-mode. The T3's emitter is an SSC P4 USVOH and it's being driven @ 900ma by a non-stock driver, which allows me to use rcr123 cells. I get 30min high-mode/ 2hr 45min low-mode runtimes with an AW protected rcr123 cell. It's quite bright as is but, as "nanotech17" suggested, it could be 10% brighter (or more) by using a newer P4 U2SVOH emitter. Here's an image of the stock controller:
I will try to find out if it's possible to change resistors to up the output from 550ma to 700ma, as I'm wanting to try a neutral-tint Cree XP-E emitter w/ Ledil Optic. I will also try to find out if some board component can be changed to allow rcr123 use, with this board. I'd like to shoot for a near 40min runtime with the stock board, rcr123, Cree neutral-tint XP-E and Ledil Optic.

Here is an image with a Ledil 26deg Optic w/ modified holder for fitting over Luxeon Rebel Neutral-White 4100k emitter:
and here is an image that shows the 4100k Rebel's tint, taken with daylight WB:
*note* There is no hotspot with the 26deg optic.
*update_3*
I cut away all 4x sides of the base of the optic holder so that it would allow the SSC P4 USVOH dome to fit (works also w/ Lux I, II, V, K2, etc.) Here's an image with the P4 driven @ 900ma, through the 26deg Ledil optic:
And since I'm doing a lot of changes I put the original driver back in, so here's the P4 USVOH @ 3.0v/550ma/26deg optic:
This is about 1/2 as bright as the rcr123/900ma driven LEDs above. I really like this optic as it lights up the whole yard, when the light is driven hard.
*edit_#4*
Stock controller @ 550ma, cr123, Ledil LXP M (26deg) optic and Cree XP-E R2_WG emitter. I put the, original, smooth reflector back in the light to try with the XP-E R2 emitter, but changed back to the Ledil 26deg optic. It's now brighter with the cr123 3.0v, 550ma current driven XP-E R2 from the stock controller, than it is with the non-stock 900ma driven SSC P4 USVOH, on rcr123:
I also have the Ledil LXP 10deg (D) and 6deg (RS) optics. I tried the 10deg, but didn't like having to move the light all around to see the same area covered by the 26deg lens. I have yet to try the 6deg lens in the light, yet.
