Where did you see that ISH272R board doesn't require a heatsink? I'm pretty sure that board needs one if it's run at anything but very low wattage, unlike the less densely populated ISH120 and ISH150 boards which don't require a heatsink under most conditions. You will need a plug for the AC...

Hey man. Just to start I'll say I have no personal experience with the LED light you're using. My opinion if you would care to hear it is that you should get decent results if you don't try to flower more than 4 to 6 square feet with that light. According to Amazon the light has an actual draw...

I have two HLG-320H-C2100AB drivers. About $80 each was as inexpensive as I could find at the time (plus shipping, although certain distributors do offer free shipping).

According to AC Infinity, two different sizes of Cloudline fans can now be connected to one controller. Have you checked your manual to see if that's the case? Or maybe Amazon has some of the older models in stock. I bought and returned a Cloudline T8 (before they switched to 110 watt draw)...

L I'd love to hear the guys explanation on that one. Do you suppose he was thinking of ouija boards?

According to the specifications on the Photontek website there are no Lumled diodes on these Pro lights (unlike the Lumatek Zeus Pro), but Osram & Lumileds Philips Diodes (like the Lumatek Zeus non-Pro models). Looks like Photontek is only releasing the Pro range? None of the somewhat less...

Did he say if this shortage is related to market supply issues in general, or is it only limited to RIU members who wish to buy Photo-Boost Strips?

Also while you have that multimeter it may be worthwhile to test the resistance of the potentiometers you bought from Kingbrite.

If you are looking to buy a light, authentic LM301B/H diodes are significantly more efficient than the older LM281B+ diodes.

Thanks for sharing your account man. Looks like you just missed the decimal points on the diode sizes. The Samsung LM301B/H are 3.0mmx3.0mm. If your lights came with LM281B+ they are 2.8mmx3.5mm.

That would be contingent on the size of the harvest and how much you wanted to convert into rosin. If you mean using grams as the go-to unit of measurement, absolutely I agree. I was just trying to help Hybridway2 wrap his head around the math to answer his earlier question.

12,000 grams wet with a 4% return to get a pound of live rosin (4% dead on would actually get you 480 grams). According to Snob's numbers this would be 2,268 grams dry weight or just about 5 pounds. You said you were getting about $2,200 per pound for your flower right?

48 what? $4,800? No, 1# of live rosin @ $50 per gram wholesale your talking $22,700. Even if you only got $45 per gram that's still $20,430.

A couple pages back Snob said the wet weight was 5664 grams.

Hey man, are you referring to the pictures the OP took of his inline meters?

Maybe there's a store that stocks the Phat filters that's within driving distance from you (hopefully for a decent price).

Many members use lights from Alibaba. You'll find some journals and other threads, but this is the primary thread for these lights. https://www.rollitup.org/t/the-chinese-quantum-board-knock-off-builds.971560/

Not advisable, could be a safety risk and you will greatly shorten the length of the LEDs life. You would be powering the diodes well over their rated maximum wattage (which is about .6 watts per LM301B diode). 218 diodes/240 watt driver=over .9 watts per diode. Not sure about the mono-color...

I'm at work so I don't have time to go into much detail at the moment. Samsung LM301B is an example of a mid-power diode. They are 3 volt .2 watt diodes that can be driven up to 200mA (absolute max) and about .6 watts each. You may want to look into voltage and flux binning of these diodes as...

The SF-4000 is 450 watts/1212 diodes=.37 watts per diode. The LEDs on the six board Alibaba light are driven harder. 660 watts/1308 diodes=.50 watts per diode.
