without heat sinks?

Selecting the LRS 350 seems like a no-brainer. How come nearly everyone who built a fixture like I'm considering used the HLG-480h-48A? Any input is appreciated!

I'm curious....the DIY link above suggests 3000k. I thought I'd use 3500k but they say '3-Step MacAdam Ellipse'. Is that something that should be of concern? Thanks!

Great light! Thanks for sharing. 2.3gpw from 5 strips?

Nice looking lights. Is this the strip you used t.ly/03M2J How large (LxW) is that room? Would you do anything differently if you built another strip light?

Does anyone have experience with Luminus Horticultural COBs? t.ly/vjG7b Under $8 for CXM-22? t.ly/83yp3

Those are terrible reviews. Thanks for pointing that out. Migrow did compare the cxm32 gen3 to cxb3590 t.ly/23rlj

I was directed here by the GrowMau vids. It seems like a great community. Thanks for having me. I've been shopping for COBs and stumbled across Infinite Electronic HK. They have a $500 minimum purchase but great prices on COBs. The 3rd gen of Luminus CXM-32 caught my eye at just over $10...
