I have a
Tool 2.0 with a warm white emitter (4000k), and one with a cool white emitter (about 6000k). [My finely calibrated eyeball reports that the cool white version appears about 10% brighter than the warm white version.] Running these on Eneloops yields reasonably long runtimes (12 hours at the medium output level), which is long enough that even assuming common Muggle obliviousness toward recharging, they can be assured of a working light in most circumstances. (Not that YOU would ever allow a battery to discharge past the point of usefulness, but others might.)
There are four well-spaced output levels, allowing the user to select the right amount of light for the task at hand, while also preserving battery life. The reverse clicky interface is simple: click the tailcap to turn the light on, then half-press the tailcap to advance through the four modes, L-M-H-Turbo. Moonlight is three to four lumens using a 1.2v cell, with the light being diffuse at that output level, producing a soft light. You can get higher outputs using a 14500 li-ion cell, but that's not the use scenario you described.
There are a number of useful reviews online to review if you want really specific information. But for Muggle-born users, the
Tool 2.0 is a really good choice. Just be sure that they know to put the lights back where they belong after using them. These lights are small enough and lightweight enough to be easily misplaced by casual users. Nuff' said.
