building my first COB 3590 setup. please help

[CobKits]

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

I'm not from USA, I'm from South America, Chile. Therefore I can not buy Robin, I need to buy everything from one hand, in fact it was the same Robin who recommended me to Jerry, because of my geographical remoteness. So I wonder, could i use a 150mm pin heatsink from KingBrite, which is made to dispel 60-70w, in a cxb3590 running at 75.5w...
Edit: Thanks anyway, I will venture to 150mm.

maybe. best to test your voltage droop with any unknown heatsink

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

im running the 140mm with cree 72v cobs at 1050ma so about 75w and heatsinks hold steady at 115f to 118f all day with just normal grow room air circulation.thats well below the rec 85c mark

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

Compound or the square tape pieces either or not both.

im good with just this? making sure

Yes, that is correct.

As Evil said either or, but not both

hey everybody! I made my order with Shenzhen KingBrite

4) HLG-320-C2100B

16) CREE CXB3590 3500K CD 36V 80CRI, CXB3590-0000-000N0HCD35G

16) CREE 3590 LED holder, Ideal 50-2303CR

8 ) LED glass lens 60 degree

16) Thermal adhesive tape for cxb3590

16) 180mm pin fin heatsink for CREE CXB3590 95-105W

im actually planing to use @Evil-Mobo idea of a c2100 diver and 4 COB

@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>

this work? should i get the storm or storm x?

 

[Evil-Mobo]

I have no experience with that bro sorry. I just use timers and set on and off times.

I am unfamiliar as well with that.
It is an interesting theory, but I dont know anyone who has done it yet to compare a side by side.

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.

Bro I did it ur way, 4 bars, plus 3 uva uvb 3ft bars in the last couple weeks.
Gorilla Glue #4
