"QB 648 Diablo available at HLG.com

This is from Horticulture Lighting Group's Instagram page, their newest board. The LM351H should say LH351H.

The previous QB288 V2 R-Spec was assembled in the USA using HLG'S own pick and place machine.

I see soo many ppl advocating hlg quantum boards and I'm wondering why they are being chosen over sf quantum boards. They use the same driver and leds plus have uv better spectrum water proof and cheaper....can anyone explain this
Spider Farmer's exclusive "waterproofing" process seems to be little more than putting glue over the diodes.

I'm curious how this process affects thermal management and diode longevity. It's certainly not how I would go about improving the water resistance of my light.

Have you seen Spider Farmer's latest price increase on Amazon? They are not less expensive anymore. For example, the SF-2000 went from $300 to $320. And remember, this is only a 200 watt light.
