YUNLIGHTS LED Driver 12V - 36W 3A, Constant Current Voltage Adapter for LED Strip Lights and G4, MR11, MR16 LED Bulbs (2 Packs)

Use them to replace halogen transformers an old display case converted LED lights. Very very easy to connect, worked like a charm.

They are exactly what I was looking for - they are a bit too big to fit small installation places but works great

This is compact and easy to install. It labeled clearly on both input and output. It lite up 15 feet per transformer without any problem. Hopefully,this will last.

Used this to replace a broken transformer for a halogen light system. Replaced transformer with this and lamps (with LED lamps) and system works like a charm!

One of the two transformers cans with a broken soldier joint on the A/C side. Was easy enough to disassemble and solder, but better QA would be good.

Hooked it up with a power cord and to a controller that connected to the LED strip and it works great

These transformers get the job done. So far had no problems with them and they are easy to install. To bad there not dimmable.

Hope it don't over heat, like review say!
