I just bought a 3 pack of these for $20 shipped on ebay, and they're pretty good for that price. Go to ebay, search on sylvania golden dragon, then sort by price + shipping - lowest first, and there are several more at that price.
I'll try and get some pics up later.
I got them to go into a small safe, and it looks like they'll be good for that. Here are some thoughts on them.
They're solid and fairly heavy - the case is steel, top and bottom, and there's a magnet with sticky tape on one side that fits into a recess on the back. It takes a bit of a twist to lock and unlock the top cover, which is slick, but it gets easier the more you do it. When it's hot and my hands are sweaty (like right now), it can be pretty hard to get them open.
It comes with 3 Chinese AA batteries installed and a piece of paper at the end of one to keep them from turning on in the package.
Shining them on the ceiling, spot brightness on high is about like my Fenix P2D CE on medium (40 lumens) with a fresh battery, and on low, it's not much different than the P2D on low (9 lumens).
It's a loose spot (looser than the P2D), with a smooth spot to spill transition, less spill brightness than the P2D, and some minor artifacts in the spill from the Fresnel-ish lens. The light is warmer than my P2D CE and is a nice shade of white for me, and all 3 pucks are pretty similar in color and brightness.
Someone on Amazon suggested removing the optic for a floodier beam. At first, I pulled the whole optic up, as it's stuck to the PCB with sticky tape, but that lost a lot of the light inside the puck. After I dropped one, I realized the lens would pull off of the plastic bracket that held it. This gets a bit more light out the front, and it's definitely floodier and artifact free, but not nearly as bright.
Also, if you have it mounted where your eye can see the LED through the hole, it's dazzling without the lens mounted, but takes a much more direct view to be dazzled with the lens mounted.
The IR reflective motion sensor is pretty sensitive up close, but doesn't react past about 4" out. Just handling it and installing it makes it turn on and off constantly, and fiddling around with it will put spots in your vision time after time. When the case isn't snapped tight, you can rotate it a few degrees to turn it on and off, or leave it with the sensor blocked so it won't turn on (but the case will lift right off).
One of the 3 has a very quiet buzz when turned on, and bringing the mounting magnet closer increases the buzz to where you can hear it in a quiet room once the magnet's on the case.
After leaving one on for 15 minutes, the recess where the magnet fits gets pretty warm - uncomfortable, but not painful. Someone on amazon measured it at about 100 deg F, and that seems about right to me. I haven't measured the auto-off time, but they spec it at 1 hour, which is probably good for an under counter light, but too long for a safe light, so I remember to turn them off.
All in all, I'm pleased with them - they'll work great for my use, and the magnet lets me put them right on the shelf rails without using the tape, light to the side. To put them at the top of a safe section, I'd need to mount a piece of steel at the top of that section, as the magnet tape won't stick to the safe fabric, but for now, I'll be leaving them on the side. This puts the LED in my field of vision, so I'll also be leaving the optic in place.
They're a little too spotty for a small area like I've got them in, and I'll play with the optics on and off, but they bring a bright, good quality light into the safe with no wiring and (hopefully) decent battery life.
