I have (6) RW150s. They work ok. Better than hid. Not near as good as COBs. You would have to email the owner multiple times to contact him. The first time a light broke, he fixed it. The second time, I just fixed it myself. Quicker and easier.

Hi, I wanted to order some more COB's. Between 50-100. It looks like the prices definitely went up. Do they fluctuate? I'm gonna hold off for now. Maybe they'll go back down?

I just put my DIY RDWC system away after 2 years. It never lived up to its expectations. I went back to all coco on drippers. I just give them GH 6/9 their whole life. Too easy.

Good point. Should I grab one of those temp guns?

I've been running my Arctic Alpines at 5 volts. On the box it says it cools 100 watts at 12 volts. I read a while back SupraSPL did some testing and running at 5 volts is plenty of cooling up to 100 watts of COB? I usually run 50-75 watts per COB. Is it safe to run the cooler at 5 volts? I'm...

Yup. .24 amps. 92mm fan. Oh man. I'm way too lazy to rebuild my other lights. According to my math, at 5 volts you only get about 42 watts of cooling? I run cobs' @ 50-75 watts each. Been doing this for over a year and I'm still learning/making mistakes.

I have a question? I usually use APV-12-5's. This time I'm building a light with 6 fans and I bought APV-12-12's. I notice you can only power 4 Arctics with it. What should I do? Order APV-12-5s or hook up 6 fans to the 12v supply which is 1 amp max. Running the COBs at 50 watts. How much...

Stop doing crunches. Check out 21st century core training.

I bought 6 Area 51 RW-150's. The other day I was just thinking about how the lights work pretty good. But, their customer service sucks. When my lights broke the second time, I just ended up taking it apart and fixing it myself. Easier and much quicker.

Try an 18/6 light schedule. Make sure the fan isn't drying out the leaves. Just a little oscillating breeze. Also, if you can somehow raise your humidity, the plant will be happier. I never used to use 18/6. But, I learned the hard way it helps when vegging with HID and COB.

Hi, I placed my first order yesterday. Had to adjust my order due to low quantity. Then, six hours later I get an email stating they are on back order? Order # 19695

I use aluminum boxes from Bud Industries.

I use that setup. The driver, 72 volt COB's, and heat sink, are all compatible. It's a 150 watt driver. 75 watts/COB I like that setup. And, 4 36 volt Cree COBS with the HLG-185-1400

Advance Auto Parts has electronic stuff. That was the best store I found locally. Online you get the best prices and the most selection. But, sometimes you want shit NOW.

I bought (6) RW150's back in like December. I ran all new sativa genetics from seed. That was a bad idea. I should have ran gear I was familiar with. Anyway, pretty sure my yield efficiency increased. I know gram/watt doesn't really mean much. But, with that said, I usually average about .7...
