Hey Sheryl & welcome to the portal. I'm no expert on LED's, I switched over to LED lighting 3 or 4 grows ago. I got a Spider Farmer 4000 after a lot of research. I didn't buy the best LED out there nore the worst but one that is in the middle of the road as far as performance combined with cost. I'm perfectly happy with the Spider Farmer. Good luck on your quest for a light!
