ditching hps for quantum lights

I got a 135W QB to replace my 250W HID light since it was abnormally hot this summer here, I must say I'm really satisfied!
It's pretty much on par with the HID but I can keep the grow tent 7° cooler, I'm sure I'll notice it on my energy bill too
Don't underestimate these lights, I got some light burn if I got it closer than 40cm

It looks cool too haha, really flat

View attachment 4185778 View attachment 4185780 View attachment 4185780 I have put 2 clones aside from the same mother vegged for 4 weeks 18l pot coco same nutes and i'll compare against the 600 and the hlg 550. this is one of the ladies from the 600w with voter's as side lights. I'll keep it even and this one in with the hlg too. it is hot at the moment but temps stable at 28°c lights on and 20°c lights off. but it did creep up to 31°c the others week. I'll post results in 4 weeks for this one then side by side in a few months. this is a grapefruit strain
Cheers. Looks great so far!
Looking forward to your results.

And if you are in europe because I saw £ sign somewhere you can also look at the hlg600 sold by an authorized retailer of HLG in europe and you get a bit more wattage then the 550 may end up cheaper too if not too late lol

And finally because the HLG product are more efficient and produce less light you want to run your room a bit more hot than hps to get a good 82F leaf temp (close to 28C) for maximum photosynthesis..

Im not too technical in knowledge there is tons of expert and studies, real life example in the LED section of this forum :-)
Thats my problem though. I want 600 watts worth of light, but need the heat as well.
But 600watt HID is a PITA for me during summer. Its a dream during winter. I save power.
 
yeah my quantum board came out just fine. 4 average plants yield was 14 oz so 3.5 per plant. very pleased. made biscuits with all the scraps and god damd the fucked me up. simmered all the leaves and scraps a whole bin full..... and put 1kg of butter in the pan ended up with 160g of super strength butter to bake with. really wasn't expecting the power of the high...

Don't buy from HLG, get a kit or one assembled from growerslightsource.com. They have a better heatsink, and they're easier to replace the boards when they go bad, plus they're cheaper!

Got a direct link?
I cant find a quantum board on their site.
What do you mean easier to replace boards when they go bad, not heard of a HLG board going bad as of yet, did you have issues with yours?

The boards simply screw in to the heatsink, they're not riveted in place. I've had 0 problems with my factory hlg550, I just think the build with the growers light source is the better option.

I've just jumped to the end here after skimming page 1. I have done a grow with a single HLG 550 V1 in a 4'x4' tent and yielded 640 grams (a personal best). This was from two seeds but i really scrogged the shit out of them - very heavy on the scrog micro management (which i grew to hate doing). Got this yield while also dealing with very high ambient temps (coz it was summer). A lot of 30+ degree (celcius) days. I've never HPS'd but I can certainly say I am a happy HLG customer, so much so I just ordered a V2.

Yeah I thought you were saying HLG would not replace the boards if they went bad.
Still cant find them for sale on growers light source, just some helios spectrum crap, did you mean growers lights? A different site.
 
I don't own an HLG-550 and anyone who did their research wouldn't own one either. Facts are facts. I've posted a visual representation of the product's performance, using data THEY PROVIDE, and the guys that already fell for the marketing ploy are upset that they don't actually have a proper 1000w replacement. I'm sorry you purchased an overpriced item that china has already copied and is now selling for a fraction of HLG's price.

What's not cool is defending an inferior product solely because you've already purchased it. Do you see the graphs? Do you see the issues within those graphs? Do you see the HLG-550 has the same uniformity issues yet still produces 30% less light output? What is so hard to understand for you? Do you just not believe the data I collected for HPS is real? Is the visual representation using data HLG provides on their product page not sufficient for you? I'm trying to walk you through it as best I can.
What makes you say that? Ive done my research and I'M still considering one. Its fucked up that they falsely claim its close to 1000wHPS but I dont need 1000 watts.... The approximate 650-700 watt equivalent provided sounds perfect for the 2-3 plants i intend to grow if recreational gets passed for my city. Either the 550 or the DIY 600 kit With some supplemental CFL, a smaller HLG light, or even a blurple light in addition this would be more than enough for me. I have a walk in closet and zero ventilation holes drilled and MH/HPS simply gets too hot for my needs.

It still might be worth it to go to the site you suggested due to build quality/replacement boards, however HLG is having a black friday sale right now on the 600 kit
