How should I custom build these LED's? Did I mention that I'm a Master Electrician?
Cobkits.com, or Timber Grow lights.....
Everything you'll need......
Excellent. Thanks for the info. To be honest, I would love it if the LED's worked out better. Give me a few days to decide what configuration would work best but I'm going to be aiming for using the same amount of watts to see if I get the same yield for the same watts. I'll run my ideas (for the LED config) through this thread so LED experts can give me suggestions if they think my plan needs adjustment. This way everybody will agree (based on facts and past experience) on what LED configuration I choose to go up against what has already worked for me in the past decade.
I'm just sorry that I wont be able to conduct the experiment until Nov '18 due to the need for perfect environmental conditions for at least 15 weeks straight.
If your using 1 x 600hps then compare it to one 600w QB or 600W of Strips.. Just do a W for w test. No need to make it complicated.
Please tag me when you start a journal or thread on it. (journal may be better as otherwise it will end in the usual shit fight...lol)
If you configure based on watt for watt, in the same footprints, the areas under THOSE LED designs, could potentially be subject to photo inhibition levels, of light saturation......
I'd rather conduct the experiment on a "production" scale. 1 x 600 would only be lab scale. A pilot plant, no pun intended.
Agreed. I stand corrected. Let's go lumen for lumen.
I thought you were going to do 6?
U need to do W for W..cause that's 1/2 the beauty of LED..its more efficient.
Yes, 6-600 watt hps in one room with the lumen equivalent of LED in the other.
What say you? Realistic equivalent to an 600w HPS with Strips?????
We should also include Samsung LED strips, or Bridgelux EB series strips, for a true DIY self customized "lamp" build experience....
It should be a watt for watt comparison.

I'm positive that even the HLG-550 will outperform an HID 600, and it only uses 510 watts.
You need to do W for W....If your using 600w of HPS you have to compare it against 600w of LED...otherwise your robbing the LEDs of what they do really well...efficiency
I am of the belief that HPS has its obvious situational advantages.....but so do PROPERLY calculated LED designs....
add another 90 watts of strips and golden.
The cost per gram comparison would be settled aswell
I haven't looked into it yet, but these HLG 550's are 510 watts total ? The 600 watt hps is more in the neighborhood of around 650-660 watts with the heat losses from the ballast core so 510 watts for the same performance would be a....(get ready for the banal)... game changer.
I'll compare the light distribution of a custom LED set-up against 6-HLG 550's. I'm thinking the custom built installation is the way to go, but I didn't look into it yet so I might be wrong. Oh! Wait a minute... I just thought of something...let's make it an LED v HPS v DE test!! Whaddya think?
Cost be damned! Let's have some fun!!
I have a 200 watt vero at about 120 watts in a tent growing 1 king tut (Sativa dominant)
I have 3 sativa dominat in a tent (trainwreck/jack herer)
It is not scientific but wow that king tut is thick in the stalk. And so tight for internodal distance i keep looking for errors. But water is good ph is good tds is good. I grew that king tut in my tent before and it was scrawny in the stem.
I personally am going to sell all of my lights and get a timber fixture to fit in the tent. 400 watts or 600 watts vero cobs because i really love that light. I love the 315 as well. But it is not as dense of plant. I could grow a monster with veros. Well 4 of them exactly
I am always contending with optimal heat. 315w to 400w is about he max where i have my tent so whatever gets that done the best is my goal. I have not tried quantum boards but from everything I have tried I love real cobs. Vero cobs. Best damned light I have ever seen and I have tried mars/mcob/cmh/
CMH is the best of those but 315 watts is good 400 watts is enough better.
I do think it should be the total cost though, for an accuate comparison.
Light, heating, a/c, food, water everything.
You'd get an extremely accurate average, because of the large number of plants.
Then match the weight to the averages
I'm subbed for sure if you do a journal. Production level grows have always been the battle cry of HID growers because it's the one type of grow that hasn't really been tried much with current gen led tech. GML is doing a side by side on YouTube right now between hps and HLG 550s that's fairly large but he had some grower error mid flower that I think is going to muddy the results. You could definitely answer a lot of questions.
