40 Watt Low Voltage Xenon Transformer 40W in Input 120V to Output 12V Halogen Light Bulb Power Supply 12 Volt G4 MR11 MR16 Lamp Driver Ballast Spot Landscape Rail Ceiling Wiring Malibu Garden

I shopped all over finding this amazing solution at a great price! Installation was very easy in my kitchen cabinets providing a beautiful clean light (I had the lights but my old transformer went bad).

I like that the specs I needed were available to replace a transformer on my under cabinet halogen lights. No problem after weeks of use.

This is an electronic transformer for driving halogen lamps. It's not a DC power supply, the output is a high frequency AC waveform. I doubt this would be appropriate for LED type bulbs, but I'm not sure. It is much smaller than a power line frequency transformer so it fit in the base of my halogen lamp fixture. There was a slight variation in the appearance from the picture - The AC input power side wiring is a black and a white wire (the black would be normally connected to the hot side of the AC power). The output side is two white wires that connect to the halogen bulbs. The leads are marked on the device which side is AC power and which side is the output for the halogen bulbs.I received my device, wired it into my halogen lamp fixture and it worked perfectly. Note that it will not run without at least one halogen bulb connected - so wire the power switch on the AC power side, not the halogen lamp side. Also note that halogen bulbs come in various wattages - choose a halogen transformer rated for more than the sum of all the halogen bulbs it will be driving. In my case I allowed for two up to 50 Watt bulbs in my lamp.The good:It works fine with no problem (as long as you hook it up correctly).It's a hard to find part that can fix your expensive halogen lamp if the old transformer failed.Very compact for its Wattage.Could use improvement:The picture on Amazon should match the actual part - The actual part has a tab coming out each end at the bottom for mounting and the AC wires are black and white (standard US electrical color code) not red.

Was excited to find a cheap replacement to power 10 5w bulb string so well below 100w. Replacing the old potted step down transformer was easy, just some wire nuts.15 minutes later however, the lights were off. Checked all the connections and they would not come back on. Absolute junk.

Works good

Delivered on time and replaced the halogen light transformer in my Broan B5636SS range hood perfectly. Just replaced it 2/25 so will update if any problems with it in next 60-90 days.

The wires were tin and difficult to work with. When plugged in, it sparked and became nonfunctional.I removed the lid and could see a black spot from the spark on the bottom of the PC board that may have touched the bottom of the metal casing where there was a black spot too. The thin film inside the metal casing did not provide sufficient insolation. I may have wired it incorrectly by connecting the d.c leads to the a.c power and the a.c. leads to the load. Good quality on the board but marginal design quality on its enclosure.

Easy to install. Performed as advertised.
