I received the UltraFire 1226 I bought via the Old Lumens sale:
(Thanks OL! I received the light in great shape, I’m very happy!)
This light is a lot heavier than I expected, but in a good way. The factory emitter is listed as an XM-L T6, but doesn’t seem as high-quality as it should be. It performs much better than the CW LB counterfeits found in recent budget lights, but the dome seems slightly off center. I don’t have the means to magnify the bond wire junctions at the moment to see if they are square or round. If this is a counterfeit, it’s a better quality one, but given this light’s performance as-is, it should be fantastic after replacing the emitter with a XM-L2 (or XP-L or XP-G2). Unfortunately, the 26mm PCB on this light is secured on the middle of the plate using glue, with no centering cutout. I’ll have to replace this cutout with an XP-board (preferably DTP) if I want to use the XP sized emitters, and I expect re-centering the emitter may prove difficult.
Second item; I had a 2-year-old but never used Dell Precision 9-cell laptop battery pack given to me for disposal. After charging the pack, I tore it down and found 9 LGABD11865 cells inside. I’ve checked the spec sheet and these are decent 3000mAh cells with 5.8A max discharge current. Four of them have already been re-wrapped with button toppers as a matched set for use in the 1226. A single-emitter light with 12Ah worth of cells should give me some serious runtime! The second four will be another matched set for use in my SRK. The last cell will be used to power one of my Convoy S-series lights which has an older lower-capacity cell installed at the moment.
