If you can find a bulb number, I would think you should be able to find a replacement 12V bulb for it. This type of fixture does not use a 'bulb'. The LED emitter is an integral part of the lamp. Emitter dies - replace the lamp. With difficulty, you could find the drive voltage/current delivered by the power module, then find an appropriate LED driver circuit and rig up the driver in a 12V accessory plug. I did that with a similar model from Walmart. It's hard to justify the trouble and expense in most cases, though, when the inverter will run at about 90% efficiency anyway.Steve

Anyone using LED replacements in these non-flourescent fixtures and find the color incandescent-esque? We replaced the same bulb I mentioned: http://www.ledwholesalers.com/store/index.php?act=viewProd&productId=449in 'warm-white', 3200K, 252 lumens, in ALL our ceiling incandescent fixtures - 3 in the bath, 1 in the cab, and two in each of the under-cabinet fixtures. The light output, pattern, and color is about the same as the incandescents they replaced, but each draws 0.15A, compared to 1.4A previously. In other words, with ALL of them on at once, the current draw is less than just one of the old bulbs. Ours is an '83FL.Steve

If you can find a bulb number, I would think you should be able to find a replacement 12V bulb for it." No such luck, unfortunately. There is no bulb per se--it's an integrated unit, and the LED is not replaceable as far as I can see. (With a 50,000 hour life, there's not much need.) Power comes from a module that plugs into a 120 VAC outlet and contains current-limiting and voltage-converting circuitry. I don't know what the output voltage is, since it's hardwired to the lamp. I could cut one of these up and find out what the voltage is, but even if it's 12 V, I'd still have to find a source for a 12 V current-limiting (sometimes called "bucking") supply. Otherwise the LED would burn up as soon as you fed 12 V to it--I've seen it happen. In short, while it's theoretically possible that this might be converted to 12 VDC, it's not going to be a simple matter of cutting off the power brick and wiring on a 12V plug instead.
