There are a ton of them out there. Seems like Evergrow has a good track record. 18 months ago I was looking into them. Everyone that said they were not good didn't seem to have first hand knowledge. They had bought high end LEDs and seem to indicate anything other than the high end was a waste of money. Everyone that had them loved them so I bought three. These were my first LEDs. After 8 months I decided LEDs were going to grow my SPS the way I wanted and decided to go high end due to the controllability. I absolutely love my AI lights but the Evergrows were/are a good value. I still use them on a softy/LPS system
I have seen picture of some melted/burnt China made fixtures. I would be sure it is from a seller with a good amount of units sold and positive feedback on them.
