Nothing in particular, I've just heard that the MK350 is supposed to be a good unit, and they seem to frequently pop up on Ebay.

Not quite. One mA you can feel. 10 mA is uncomfortable. It takes about 100 mA to stop your heart.

Wanna save some more? Step out of HD and check out this place: http://www.uaac.us/aluminum-angle-34-x-34-x-48-in-116-in-thick75in-4-ft-2-ft-new-usa Can't believe how inexpensive these people are... Too bad they don't do heatsinks.

two weeks old today: I trimmed off the two damaged leaves after taking this pic. They were all crispy and dry.

Your fucking hopeless.

Problem with that kind of profile is there is much less surface area in contact with your water. Plain square tubing maximizes that. The EZtube you showed above would work much better.

I don't know that much about them to really say how "good" it is. I just know I want one. If I had 600 bucks to spare the MK350 on Ebay would be on its way to me right now.

Watch Ebay too - there's a used UPRtek MK350 ($3500 unit) for $600 right now: https://www.ebay.com/i/183253248248?ul_noapp=true

Wow, now its 50% down 6 inches from the center. I think my foot IS bigger than that.

Dude you are SOOOO fucking wrong there its laughable. LEDS are 40-50% efficient. Thats is a fact. HID is 30-35% efficient. That is another FACT. That whole 90%/10% thing is just crap you pulled out of your ASS and it makes you look like an idiotic fanboy. Yes, LEDs are more efficient, by as...

I agree 100%. Less government intrusion the better.

3500K is not far behind at 198. And like I said - you gain efficiency by running them softer. 3000k is 187 at test. Use the simulator to run them at whatever configuration you can think of.

Thats at test current, you gain ~10% when you reduce the current by 50%. The Q strips at test current are 202 lm/W in 4000K: https://www.samsung.com/led/support/tools/engine-calculator/

Its just flat out wrong, or its based on outdated data. Todays high efficiency white LEDS are far more than 30% efficient, reaching well over 200 lumens per watt - that's 33% more light per watt than HPS - even when converted to a PAR value.

I've got a couple of cheap lights like that too. I got them when I first started. They are *ok* for what they are, but I would not recommend them to anyone TBH, there's just too many other options out there now.

Word. The 1010 profiles are pretty pricey compared to the Quickframe stuff they make.

No, you're talking about some sleazy seller making a buck off the Quantum Board name that LEGALLY belongs to HLG. These guys are literally stealing money out of the pockets of HLG, by cashing in on the reputation of HLG's trademarked product.

Yeah, and like the Platinum, its spread is horrible. Over 50% down at a mere nine inches from the center. Its basically got a foot print a bit bigger than my foot.

Look into strip lights from Samsung or Bridgelux if you want efficient natural white light. You can easily get system level efficiencies of 2.4 uMol/J compared to ~1.6 you get with HPS. Most of the blurple panel type lights will be in the 1.4-1.8 uMol/J range by most estimates. Its difficult to...

Not a bad little build - you'd be hard pressed to make one like it for under $100 without any volume discounts.
