Fine - with a caveat – Flood-to-Throw Zooming Cree P4-WC 3-Mode LED Bike Light with Mount (3*AAA) Reviews

Involvement:General (knows how to use it) - Ownership:more than 1 month

Pros:
3 modes [low, high, strobe]. Good build quality - tough without being hefty. All-metal body. Reasonably bright, and you can change the focus from flood to throw by rotating the head. Works with 3XAAA holder [included]; rechargeable LSD NiMH AAAs work well. Also works with rechargeable Li-ion 17500/18500 [I've used both]. 17500/18500 are brighter than AAA, but rattle around inside, even with rubber washers. The mount was tight and easy to use. All in all, fine quality.
Cons:
IMPORTANT PROBLEM: light would change between modes every time it was bumped or jarred in any way. On a bike, this includes going over a pot hole, random bumps in the road, gravel, going off a kerb, etc. Brightness was OK, but not great with 3XAAA. Much better with 18500, but then the rattling was worse, and the automatic mode-cycling gets worse. Loose contacts between AAA holder and rear of light.
Other:
SOLUTION: 4 magnets [SKU 13518] placed on the negative end of the AAA holder made the contacts tight and solved the mode-cycling problem. I don't think I should have had to fix the light after buying it, but at this price, I suppose some fiddling is acceptable.
Bottomline:
Functions best with magnets at the negative end of the AAA-holder. A good light for the money, but count on a little bit of fiddling to make it work correctly.
