DIY Passive cooling with PIN Heatsinks SST120 and SST140

[Lopez7808]

Wow very nice plant

 

[Evil-Mobo]

Yeah bro you should defoliate in the center/inside especially to improve air flow and help avoid getting PM.

@The Dawg Please share Tea recipe for my tomato plant when you get time.

Moved my tomato plant from a 3 gallon to a 5 gallon pot.
2x2.5 tent. Photon 180 lamp 190 watts
Canopy is thick and leaves on top feel a little moist... should i do some trimming to improve light penetration and avoid mold?

Holy Mater Plant Batman
The Dawgie Dawgs Tea Recipe

This Recipe Is For 1 Gallon

1 Palm Full EarthWorm Casting. I Use Ancient Forest
3/4 Teaspoon Unsulfured Molasses I Like Black Strap Cause It Contains Magnesium And Calcium
1/4 Teaspoon SubCulture B
15 ML Hydroplex I Use AquaSheild Which Is No Longer Produced. Which Is Why when I Heard That I Bought Every Gallon The Hydro Store Had

Mix In A 5 Gallon Bucket And Bubble For 48 Hours And Strain
Store In Refrigerator Un Capped And Shake Daily. Tea Will Keep For 7-10 Days. For Best Results Use Immediately

Those boards are weaksauce ,they wouldn't even be worth using as side lighting.

Think this might work for aeroponics? Or would there be too much debris in the mixture.

Do you bubble it at room temperature?

can i would you say a palm full would be like 3/4 of a cup or so?

Hey @robincnn , I asked this before but could you put two of those splayed heat sinks in a Photon case if you cut the top off thecase off to allow the pins to stick in the air. Or is the problem horizontal space ?

Splayed too big for Photon Case

 

[bri77]

Damn. Close. A slightly wider black Photon with two of those sticking out the top would look awesome.

Yes 70V is more efficient

For 10,000 lumens you need. (10,000 is a random number i chose)
90.2 watts with Vero 38V
80.8 watts with vero 50V
74.2 watts with vero 70V

Thanks, this seems like the best option for me in Canada. I actually just sent an email through your site inquiring about shipping the SSTX to Canada.
Can you tell me what the difference would be in using the HLG-185H or 240H? They are both available through Mouser in Canada, though a bit pricey.
Also is 4 of these at Vero29 3000k good for a Veg/Flower 3x3 Tent, or would I want 3500k or multiples of mixed spectrum.

3000K is good , if not in stock 3500K is good too
HLG-185H or HLG-240 are both good, 240 is more powerful. 185 or 240 go with ether, whatever is better compatible with COB.

For 52V Vero at 2100ma
HLG-240H-C2100 is a good choice as HLG-185 is not available 1400

52*2.1*2=218.4watts at cob + driver losses

For 70V at 1400

2x 67.3= 134.6V


For 70V at 1750ma


68.5*2= 137V



For 38V with HLG185 top is 1400ma
so you can run 4xvero on HLG-185H-C1400

For 38V with HLG240
4x vero on HLG-240 H-C1750

For 38V with HLG240
3x vero on HLG-240 H-C2100

I ordered the hlg-240h-c1750B waiting on 4 of them myself . I agree that this drive would be very nice to use. Still need potentiometers.

 

[TheHypnoToad]

Thanks for this info, the 70V Vero are $10 more each for me, so I'd rather take the 50v and run them off two drivers for basically the same cost. That way I could also add another COB to each driver later on if I wanted to expand it. Does that make sense or am I missing something that makes running 4x on one for the same cost better?

 

[black_thumb_808]

Please sell me some 140mm+ heatsinks for CLU048-1818 running at 75w

thanks

140 is out and not coming back. Try SST X or give me 2-3 weeks, i will have some SST133. 133 has pin size and density of 120mm and may work as good as 140

ya 70V is more expensive. not sure ut it looks like 70 v is 12.5%more output for aprox 40% more price
50V is good enough. Adding another COB later depends on driver

thanks for the reply.

how wide is the SST X? can it handle 048 1818 at 75w?

 

[Lopez7808]

@robincnn I noticed that sst140 heatsink are hard to find. Have this heatsink gone out of production?

[Lopez7808]

Where can I get a photon case?
Been thinking about doing a case with 4 cxb3590 so I might need a bigger case.

 

[Lopez7808]

Just got my HLG 240H C1750B driver. Thank you Santa

 

[Lopez7808]

Not sure what to build with these drivers, any suggestions???
