Has anyone tried these ARCTIC silicone thermal pads? Finally getting ready to build and thinking this will easier than thermal grease. I see Cutter selling the pre-cut graphite material for the CXB3590s, but it's out of stock. This silicone pad has a 6.0W/mK thermal conductivity rating.

Hey @Growmau5 what hardware are you using to hang the heatsinks in your 3590 build?

Awesome, thanks for letting me know. Do you know what reflectors or lenses @littlejacob used? I am planning on using 80 degree glass lenses on 38" heatsinks for the flower bar. Those would be spaced at 9.5" on center. The veg bars will have the COBs spaced 15" apart. Should I go with a 90 degree...

How do you think it would be covering my 3' 9" x 3' 9" vegging area with 4 x CXB3590 @ 49W each? The spacing would be 15" on center between COBs. Would this light distribution be alright for veg? BTW, how do you calculate PPFD for the various setups you are designing?

Many thanks for your detailed reply, how much area do you have the HLG-120H-C350B with (6) CXA3590 5K DB covering?

@yoda Thanks for your reply, my question is more about COB and driver pairing to get good PPFD and light distribution for vegging this space. I am thinking that if I go with 4 x CXB3590 36V @5000K / HLG-185H-C1400B and cut the 38" in half so that I can get better light distribution, then it...

Hey @SupraSPL thanks for helping all of us get into this awesome technology. I am going to go with your 4 x CXB3590 36V @ 3500K / 1400ma driver build recommendation to add to my flower room. Need some lights for a 3' 9" x 3' 9" vegging area. Do you have any recommendations for this? I believe I...

Awesome brotha, I can't wait to see the results! I am still trying to understand the matching of COBs to drivers and how to calculate efficiency. I watched your video on Dude Grows, but I am missing a few things. I have two main questions: How does Supra calculate how many COBs a specific...

Loving your content, as always @Growmau5. Gearing up for a build inspired by yours. How are those 700ma drivers working for you? Would you still use them if you were starting over on the build? Was not familiar with the X-Carve. It looks awesome. Definitely going to make a place in my garage...

Hey Growmau5, loving your YouTube channel and the builds. Heard your question in to Dude Grows about using perlite and BluMats. Did you figure it out? I am looking to use BluMats with a soil, coco and perlite mix and wondering if I need to make any adjustments to keep the probes working...
