I see, One to control all three supplies. If using only one driver it would still be 100k? I'll be running 3 boards in parallel with the "( HLG-120H-C1400 with 2 or 3 or 4 boards for 170 Watts)" I have a 100k pot hooked up now and it doesnt completely dim the panels though I didnt expect it to...

How did you arrive at this number?

I think theyre all 100K Ohms. Check out page 4 http://www.mouser.com/ds/2/260/HLG-240H-C-spec-806189.pdf

Oh Snowflake, Trump won, get over it and grow a pair or do you need a tampex?

I saw on the news awhile back that some people got temporary cards in Pennsylvania. Anyone else hear this or know how to get one until Pa. gets it's ass in gear?

Umm, you don't suppose they already took that plane apart and raped every inch of it? no,no, I'm sure you're right. I'm sure the Chinese respected us and didn't touch it. Our secrets are safe with communists. :wall:

Thanks, I do plan to make them slide for even distribution across the floor to start with. I found a Lux meter app for my phone which is a cheap way to determine light spread for us non-scientists. You gave me an idea to use the center holes and attach a piece of either steel or aluminum flat...

Question 2 My room is 3 feet long - 2feet 4 inches wide - and 4feet 3 inches high. Basically 3x2x4 I'm into passive hydroponics. I have 2 plastic storage totes that the pots sit in and I water the totes and the plants suck up the water. They fill up the room width wise. So would it be best...

Got all my parts , now to put it all together. The problem I'm having is how to mount the heatsinks. I have this nifty track aluminum with a notch cut inside but the heatsink plus LED panel is too thick to fit in the notch as well as being too crowded. I was thinking of getting some flat strips...

No, I'm merely aware of my surroundings and hate to see the government pissing away my tax dollars.

More than I did, then again I don't get food stamps, waste food nor weigh 300 pounds.

Interesting. I just read an article in The Whining Liberal about this.

I'm thinking about switching to LED lights instead of CFL bulbs but my rooms will get too cold in winter. Saw this on TV and it may be perfect for my small rooms provided it doesn't catch fire. https://www.handyheater.com/?utm_source=Shopping&gclid=CMu2rIGd5NACFVlMDQoddd0NSQ

This guy.....

Somewhere here in RIU we were talking about this before. There is a ultrasonic frequency someone mentioned but I have no idea what it is anymore. I thought about taking a ultrasonic jewelry cleaner and tweaking the frequency.

I'm reading about those now and they seem to be a good solution to my room. I'd like to build my lights after working with electronics for 25 plus years and have a metal shop at my disposal and I see these boards arent plug and play. A bit pricey @ $75 a piece and not many results yet. Good info...

I'd like to build a COB light set up but my room is only 4 feet tall. I read lights like the 3950's need a good 10-14" away from the canopy to prevent bleaching. Would a light like a 3070 be more friendly?

That's like Christmas come early. The pins are really nice and of good quality.

Had to look that one up. The brown note didnt work either.

Jew detector? Now I've heard everything.
