Great Govee Permanent Light Power Supply Replacement!

Matt—October 15, 2025

I used this to replaced my power supply for my Govee Permanent lights supply. This has worked great! I have it attached to the side of my house and this sees all the Iowa weather. From muggy summer 90F+ days, to - 30F winters, this has worked everytime. Read more

Nice power supply, not too much RFI

krisp—September 6, 2024

Power supply puts out a solid 48 volts. I didn't have a load that would precisely pull 300 watts out of it but I did use it to power the bias circuit of a 50v device which draws approximately 2 amps and it worked fine. Not much noticeable increase in RFI but I didn't check the entire ham spectrum, and switchers like these tend to be noisy somewhere. Hopefully just not somewhere important! Read more

★★☆☆☆

Generates too much Heat.

Montel—August 30, 2025

Too Hot! I measured the voltage output and it was correct. But when I connected it to charge a solar generator, with an MPPT controller, It got EXTREMELY Hot. If I had not discovered it in time, I believe it would have started a fire or melted something. Read more

Does not cut power immediately on the low voltage side.

Javier Perez—July 28, 2025

If you need it to cut power immediately from low voltage side, this ain't it. Maybe this still suits your application but it did not suit my application. I needed it to cut power immediately from the low voltage side once disconnected and I could clearly see residue voltage (on the 48v side) after unplugging it from the electrical outlet (unplugging the high voltage side).
