Cheap LED 12V clamp light

[Feral Cement]

I'm not sure if this is the best place to post this (in the power generation/storage/conservation forum) but Lowes has these 110V clamp lights with 24 LED bulbs for $22. No good on a boat you say? The plug reduces 110V to 10.5V DC which is in range for a 12V system. I cut the plug/transformer off and hot wired it to a nearby battery and VOILA! a very bright light that draws .5A/Hr, on a gooseneck with a big clamp on the end!

Looked like a promotional/sale item so you might want to get one or more soon if you like the idea of moveable bright lights.

There are times when your 12V system sees voltages in the order of 14 sometimes even 15V or higher depending on what kind of batteries and charge profiles you have on alternator, inverter, or solar panels, etc.
These will burn your LEDs within 1 season.
There is a voltage regulator with 10.5V output inside the plug. You might still want to utilize it before you burn those LEDs. My guess is that inside the plug, 110V gets stepped down via transformer, then it gets rectified via diodes and then regulated. So you want to throw away transformer, and diodes, but keep the regulator. Connect regulator input to your 12V system. If i am wrong about the contents inside the plug, then you need to regulate the current to your LEDs.
Make sure you fuse your new tinkering experiment.
