CobKits said:

the SSTs are the same ones i sell in fact i get them from robin. 140x80 mm good to about 80W. i dont speak to heatsinks in mA as its not directly related to watt load due to all the different cob voltages out there. a watt is a watt.

jerrys prices on heatsinks are good especially if you live in asia. shipping them to the US not so much.

im not a heatsink expert but ive been told that you get to diminishing returns with larger diameter ones

i just use and buy what robin does because hes on the edge of that stuff

This is for all PIN heatsinks, or just for northengrowlights selling ? Evil-Mojo says SST-140mm (designed to dissipate approx 50w), is enough to dissipate the 75.5w at 2100am. My question is, i really need a larger/heavy heatsink like 163mm, designed to dissipate between 75 and 85w, or a 150 mm heatsink, designed to dissipate 60-70w have enough?

From Jerry (kingbrite) :

• Φ120mm*H70mm(for 40-50W): $9.5usd/pcs
• Φ133mm*H70mm(for 50-60W): $10.5usd/pcs
• Φ150mm*H70mm(for 60-70W): $13.5usd/pcs
• Φ163mm*H70mm(for 75-85W):: $15.5usd/pcs
• Φ180mm*H70mm(for 95-105W): $17.5usd/pcs

@bassman999 do i still have to use "Thermal Compound" to install "Thermal adhesive tape and COB" to the "heatsink" ??

@bassman999 @Evil-Mobo what you guys know about the storm & storm x LED Controler?

Im very interested because this closely mimics nature's natural sunrise and sunset profiles, witch is mean is a energy saving, see pic and info on page 4 of the link>

Example- My current build is:

(4) CXB 3590 80 CRI 3000K
(1) HLG 320-C2100B
(4) 140mm pin heat sinks
(4) COB holders
(4) Khatod Silicone Lenses

I am currently lighting a 3x3 tent with it with no issue, most other guys around here want 8-12 COB's in the same place and drive them softer, if using pin heat sinks this drives up cost a lot. You do the same build in bar style configuration and build about 4 -5 of these bars and you're only using 16-20 COB's that savings adds up. Less drivers too.

This is why I went the route I did for mine.
