Grower lights depot is a sponsor here and they carry hlg quantum boards.INot sure if HLG is a sponsor here.. but the best advice i got was to get kingbrite qb's off alibaba. the 250w was $100 less shipped, same exact LED's the samsung 301's.. amazing deal here in 5 days. I wanted to buy HLG, but they never responded to emails for me.. ended up saving a ton
Weird....hlg has always responded to me, one time in less than 20 minutes. They have fantastic customer service usually.....wonder what happened there.
