I've had the light for quite a while, but I've never used it as I received it with a broken lens. I ordered a replacement from KD, but it was *just* too large, and I lost interest in the light after that.
It's attractive, fairly well-constructed for a %$!*Fire, very nice OD colouring, comes with a plastic spacer tube for 18650 use, and a generic 3AAA holder. Beam pattern isn't too bad (narrow throwy hotspot, wide corona and even spill with no Cree rings), but the tint is blue, it doesn't tailstand, and it's not very bright. But, if you're looking for a light that will work on multiple power sources, I guess this is it.
Mine is a 2-mode hi-low with memory. No annoying blinky modes. :thumbsup:
If you're looking for a dedicated thrower, for $9 more, DX sku.17382 blows it out of the water as far as output is concerned. Build quality is very nice, although the LED tint is, again, leaning to the blue side, and the beam is fairly ringy. It also has an annoying two-stage resistored tailcap (click once for high, click again for low, click a third time to turn it off). It's about the same length as the C-308, but the head is quite a bit larger in diameter.
For a general-purpose light in the $20 price range, I'd suggest a good P60 host such as the UF 503-B, or for a few dollars more, the Solarforce L2 is a wonderful light. They're a tad smaller than the C-308, and the flexibility of being able to change the LED module is a big plus.
