It took me a while to find the right niche for my Infinity, but I've finally discovered that it's a perfect light for keeping within easy reach in the car. My wife can grade papers with it, or we can use it for reading maps or looking for whatever's rolled out of reach onto the floor. It's bright enough to read a map by, without being too distracting to the driver. The trivial cost per hour means that we don't have to have any concern over running it for a long time, unlike a photon.
We tried a dimmed-down Eternalight for reading on the road, but the pulsing that the Eternalight uses at the lower brightness settings is somehow disturbing for reading, at least when in motion.
That said, it's still too chunky to carry around regularly.
