LED Driver 200W 12V LED Power Supply Transformer Adapter IP67 Waterproof 110V AC to 12V DC Low Voltage Output with 3-Prong Plug 3.3 Feet Cable for LED Strip Lighting, Outdoor Use

Excellent LED driver — it powers my LED house number reliably and performs exactly as expected.

Converts my address sign to 12v and works perfectly. No problems so far. Is

Works like a charm. I replaced my old one which was not working properly. I’m no electrician and this was simple.

UPDATE: seller contacted me after reading my review and offered to refund my money. They didn't even ask me to send the supply back. Kudos to a good seller for having good customer service! I still don't know if my unit was defective, or just not the correct type of supply for my purpose (I needed regulated constant voltage, but the mention of LED use makes me think this might be constant current, but difficult to tell with limited/conflicting specs given -- both LED use mentioned as well as DC cameras, etc). So I raised to 4 stars since ultimately it didn't cost anything to try it, other than the time involved. Initial review: I planned to use this supply to drive 10 Buck/boost regulators (the model with adjustable current limit, Amazon part #B0781JC2WK) for up to 10 strings of LED garden lights that I am converting from solar. Power needs here are minuscule -- only 100mA per output, so 10 regulators, around 85% or better efficiency would still be very close to 1A total with all 10 strings used. With all 10 unloaded regulators connected, it seemed to work fine with a single strand of lights going (did this to adjust each regulator to ~100mA) but when I connected 5 strings to test half-max current and check heat levels on the regulators, it did some blinking on for a fraction of a second over and over thing like it couldn't handle with that much current. Maybe this type of supply is the wrong type for this use case? It mentioned being used to run security cameras, so I assumed general voltage regulation up to 2.5A was within its capabilities. I switched to my Meanwell 8A supply (Amazon B019GYOMN6) and everything worked perfectly, drawing a mere 350mA total current. So in order to not waste an 8A supply when less than 1A was needed, and to get a smaller one that would fit in the same enclosure, I ordered a Mean Well 12v 3A supply (Amazon B0180WDIKS). My instinct is to always use Mean Well supplies in my projects, and with the simple needs here, and the large number of positive reviews, I decided to make an exception for the sake of a nice weatherproof package and nice size that fit well in my enclosure, but it was a mistake. Something as simple as a 12v supply with less than 0.5A needed seemed like an easy enough task to risk it, but no. I won't ever use any unknown brand of supply on future projects, and I recommend the same for you. And really there wasn't any need to bypass Mean Well on this one, since the 3A weatherproof equivalent from Mean Well was actually the same price, within a dollar.

I use these for my fishing green light to change from 12 volt battery to 110 electric plug on my marina boat slip.

Great quality

Seems to be working fine :-)

Looks good.

Works as advertised. Only had a few weeks but working right now.

Funciona muy bien

Works. That’s all I care about.

Arrived ahead of time. Installed in 5 min, no issues with slow start-up or otherwise.

Works perfectly with the exhaust fan I purchased for my small trailer. I’am giving its 4 stars because it is not installed yet but once it is I will comeback and let you know. So far so good.
