Nope, I didn't read the
reviews, I'm giving you a user review.
I looked at one at the store, and realized that for a bit more than the cheap push button multi LED battery lights that use AAA batteries and produce cold, spotty uneven white light I could get a light that worked great and looked a lot better to boot(nice small stainless puck).
As far as I'm concerned they
work great, and have for months now. My neighbor has switched to using them to light his boat in the evening almost entirely, with several of them facing up and bouncing off the cabinets, and we have
shore power here. They aren't motion detecting(which some of the reviews complain about and give low stars for) just that they use a small optical
sensor in place of a switch, so you can swipe over them to turn them on. When they get low on battery, the sensor range decreases, and the light flickers to warn you they're low. No accounting for user error.
Nice warm white light, convienient to use, and cheap. I prefer it to read by vs my 12v light(poorly placed, cold white cluster LED, lower output), but that will change with my
lighting upgrade, at which point these will go to the lockers,
head and other places that 12V isn't easy.
My head has very little
headroom, and I prefer a thin overhead light no wires since it's directly on the
hull.
I use them, because my wired in ones suck, and I'm waiting for new ones, and because they are good to have in lockers, or places where a wired light isn't needed, or convienient due to infrequent use. There are many times and places where battery over wired is a good choice, not the least is the
engine bay/electrical panel, as I disconnect the battery when working there which means no 12v
lighting.
The low battery draw means I seem to replace the batteries every 3 months when I use the light most days.
So basically, if you were going to use the cheap
puck lights, look at this as a nice upgrade that hits most of the points those didn't. If you're looking to replace constantly used 12v lights, look at something else(I like lunasea lights for that:-))
