Thanks to BessieBenny great review, recently ordered Romisen RC-G2 (actually few of them
). I will leave one in stock form, because even with inferior Cree P2 it is still a great flashlight. My intention is to be able to use both AA and 15400 cell in modded form. I had 5-mode buck/boost driver from DX (sku 15880) lying around, which looks ideal for this purpose. I didn't like idea of ruining original heatsink trying to remove glued LED and soldered driver, so I decide to make my own. My heatsink is 0.5 mm larger in diameter then original, so I was able to press fit driver in heatsink without to much sanding (only about 0.3 mm, from 17 mm to 16.7). I could use driver in original shape, but then thickness of the walls would be only 0.25 mm, maybe a little to weak.
LED is SSC P4, USXOH from Kai, with Vf of 3.25 V. LED is glued in place with Arctic Alumina thermal adhesive.
Before I soldered leads to LED, I measured current. From Sanyo AA 2500 mAh NiMh current on high at led terminal is about 0.3 A. Didn't measured mid. and low. At the tail cap current is 1.3 A on high, 0.37 A on mid. and 0.06 A on the low mode.
Unfortunately, I don't have manual settings on my camera, so after many attempts, I didn't achieved useful beamshot at different settings, because there is barely visible difference on the images at low, medium and high output, but in reality difference is very obvious. High is brighter then stock output, medium is like my MiniMag 2AA with TeraLux MiniStar2 LED upgrade, and low is like Solitaire, but still usefull.
So I only showed stock and moddified high output beamshots. Distance is 1 m from white wall. Compared to stock G2, throw is about the same, but spill is much more usefull. Original Cree was a little bit greenish, P4 is more on the white side. Anyway, great flashlight is now even better. I already ordered pair of 14500, with that Lithium power this will be one mighty EDC flashlight. Will post current draw and beamshot when I got that.
