They make boards that replicate full spectrum sun light not just kelvin adjusted. Try chilledledgrowlights for some serious modern pcb leds that compete with fluorence kind and others at a better price break. I have used hps cobs and looking at pcb like chilled color corrected with uv ir reds blues whites

I'm not a good DIYer lol. I'd rather purchase something plug and play.

here's my opinion:
In 5 years if you are using HPS lights over LED for a commercial grow you will probably be on the verge of going out of business. In a big grow room LED's will simple grow 50-100% more once you start stacking your grows (pallet racks) while your utilities will still be relatively the same as when you used HPS.
The costs of LED will possible be less than HPS in due time. Right now we build our own lights because it saves us a ton and it's hard to find anything pre built that is affordable. I grow with doubled ended HPS (new bulbs) right next to mid grade DIY led's (cxa3070 AD top bin) and there is no difference outside of I finish about 4-5days faster.

you know, you're right. i reread some things, and the advantage comes from leds producing more lumens per watt than hid lighting, so you can run less wattage to get the same lumens

Yea that is correct, since they produce more light per watt you can use less wattage to achieve the same effect, which will lower the heat load.

they pretty much are now if you DIY. a gavita with 2 bulb changes are $550+
a 675W cob rig will cost you the same and save you $200 a year in electricity and you'll get 10+ years out of it without bulb maintenance

I agree that in 5-10 more years LEDs are gonna be a whole heck of a lot better, i remember when they first came out compared to the ones now, what a huge difference.

Whats a commercial grow?

Only problem is in my opinion no 675w LED will compare yield wise to a 1300w DE gavita. The yield losses would pay for the gavita in one run alone in my opinion.
Here's a great side by side, basically what you just said, (1650watts of top bin citizens vs 2300w of gavita), the gavita yielded 50% more.

To me results like that show you gonna need nearly even wattage to compete with these DE and CMH lights, and at that point you just lost the only advantage LEDs had since their spectrum isn't that desirable.

Is this being serious or just fucking around? You mean ill save 1000 on 5 DE's annually ? Doesn't even make any sense put this way. No body makes that bet, not even with the heat. DE's are top dogs in commercial set ups, we all know that.

ok if youre gonna crank your gavita out to 1300 then use 900W of cobs, same difference, same 30% reduction in power and heat load
false and youre probably the only person on this board with that experience

They used 1650w vs 2300w , which is more watts than you said, you said 675w to replace a gavita, that side by side used 825w per gavita and the LEDs got smashed by 50% more yields. And the results speak for themselves , really nothing at all to do with me i had no part in that test.

I'm pretty sure most of the guys in this section make these claims off the top of their head, with zero research or knowledge about what they are saying.

"are" for now because theyre entrenched. youd be short sighted to equip a full operation with HPS today since LEDS cost half of what they did just a year ago. thats just a fact. if people want to equip a warehouse with HPS and are happy with 1-1.2 GPW so be it. doesnt mean there isnt tons of room for improvement over outdated arc tubes

You're crazy bro, all the big grow ops here in colorado use DE lights with a 2:1 combination of HPS/MH , you just talking out your ass again. DE lights are THE BEST for warehouse grows PERIOD. And i really don't wanna hear more stupid shit outta you either stop making up random claims with no facts to back them up this whole section is being misled by a couple people that literally don't know shit about growing.
