That's a crazy amount of money for some lights Jesus Christ. Especially when something for $100 will do the same thing.
Get shrimped out!
I do think its pretty pricey too. I did spend about $200 on the 100 Watt 10k Lumen floods and they don't even make a dent so I was just going to step up my game. I hope to use my system to grow rare aquarium plants at great speed and sell them. So its an investment and LEDs last minimally ten years and don't lose much brightness or get very hot as compared to fluorescents and HIDs, respectively.
