The samsung diodes are the real deal and the dimming function is great. Bought grow lights, fans, a humidifier all quality. Now that i've upgraded to ac 3x3 tent i have no problems.

Customer service is the best, they always respond in a timely manner. Loyal ac infinity customer for life. Every product ac makes is an excellent value for the money!

If u get 2 of them. It's cheaper then getting the next size up. Saved 50 bucks that way tho. Prices are fair.

Bought sf evo 2000, and hope for better quality, and at least it has a 5 year guarantee, i hope they honor. I believe the driver over heated and burned out.
