12V LED Power Supply Driver, IP67 Waterproof Constant Voltage Transformer, 120VAC to 12V DC Converter for LED Strip Lights Cabinet Lights and G4, MR11, MR16 Bulbs 15W 1-Pack

Great size for my needs. This resides in an exterior metal box as the trigger for a pool salt water system where the flow switch actuates the relay and then it switches on the salt based chlorine generator. Several months into an EXTREMELY hot summer (AZ) and it's working flawlessly.

This greatly simplified converting my bench-top magnifier lamp from a florescent bulb to LEDs. It fit perfectly into the enclosure that contained the old transformer. So far, it's working great.

I installed this in a box behind and existing light fixture to get LED source for accent lighting. It fits nicely in the box. For a couple of small LED spots or strips, this worked great. It's power output is a little low so it may not drive an entire 32ft string without overheating.

Bought for a 12V LED strip. The size is perfect for 15W, love the round shape compared to the other bulky rectangle ones out there. Wiring was easy, works perfectly with a dimmer knob. Would definitely buy again!

Very hot when powering around 6 feet of led strip lights.

Wired power supply to a 120Vac outlet in RV kitchen island. Used the 12Vdc power to power a relay and under the sink cabinet lighting I added. Works well. Used cabinet door switches (Cabinet Door Switch for Closet Light Lamp Switch Automatic Touch Switch for Wardrobe Applicable to 12V 24V 110V (Black)) to control power to the lights.

I have a number of fixtures that use the MR16 halogen bulb, and was looking for a way to substitute the 12v LED version of these bulbs, which would not work with the existing transformers in the fixtures. These transformers are easy to install, and small enough to fit nicely inside the fixtures, and now I have LED lighting instead of halogen.

I used this to convert a socket to power a camera and it works perfectly.
