The Inova Radiant C sold at Target is a fairly nice light. It runs on 2-C cells. It's got a reasonable throw with a large hotspot and good spillbeam. The beam quality is very clean with no visible artifacts or donuts. I'm quite pleased with the light output, and the runtime is significantly more than 4 hours. Significant reduction in output seems to occur somewhere after the 4 hour mark. It's got a lanyard bar in the tail, rather than a clicky like the Radiant AAA and AA. The design is pretty basic- a plastic head cover, permanently attached to a one-piece body, with a plastic screw on end-cap, and an aluminum tube that slides into the plastic body, and contains the LED, electronics, and cells. Inova's tolerances are pretty impressive even on this cheaper light- the plastic body has tolerances under a few thousandths of an inch so that the aluminum insert can be inserted without stressing the plastic, but has absolutely no play within the shell.
Negatives: The switch, mounted on the body behind the head, can be a bit hard to find in the dark- I wish it were raised or indented, rather than being flush with the body, although the rubber cover is coarsely ridged. The design relies on a snap-on bezel to maintain pressure on the batteries, which might eventually become a weak spot after enough years or enough abuse. Inova's warranty would probably mostly negate this possible weakness. The "vents" in the plastic body might allow some air circulation, but the thin aluminum sleeve that contains the heart of the light certainly won't sink heat like some of the more expensive all-aluminum lights. The squarish shape makes it the ultimate anti-roll light.
Nevertheless, it seems pretty tough (it withstood a 15 foot fall onto concrete with only a minor scratch), has good light output, a good runtime, and is priced reasonably. I think Inova also supports it with a lifetime warranty like their more expensive lights.
I liked it enough that I've purchased several. I paid $30 at Target.
