      Hey how's it going. I understand very little about LED but I'm learning. I'm running 12 hps 1000w lights and would love to lower my power bill and keep the same yield. Definitely not the best with tools so I would like to play LED rights that's ready to roll. Can you help me on which would be the best buy. Thanks.

        These are 1000w single ended bulbs?

      Hey, looking for some guidence, planing to light up a 4x4 with cxb3590 3000k 80 cri, i'm interested in max efficincy so should i use 12 or 16 cobs with a dimmer, which driver would you suggest? (3 MEAN WELL HLG-320H-C2100B?). Also does pin heatsink size matter? 140mm vs 180mm? can the cob benefit from a larger pin heatsink than it watt recomends?
      1. Rahz
        Rahz
        You need to do some more research. Cree no longer has the best or cheapest cobs. Citizen, Bridgelux both have better products. Heatsink size does matter but it depends on cob wattage.

      Hi Rahz!

      Huge fan of the multiple CRI grow I saw the results of. I'm about to pull the trigger on my cobs (leaning 52volt V22s for $14, unless there's a solid reason not to) and was wondering if you could give me some CRI/PARw advice.
      2 tents, one 4x2x6 for veg and 60"x31"x84" for flower. 3 plants DWC.

        Any clear flaws/improvements you'd make? Trying to make the most effective light I can for the money I'm going to spend, and all I have backing this up is dozens of hours reading forum posts. Thanks for any help you can give!

        The veg is overkill, just incorporate a dimmer knob.

        The flowere lamp k/CRi will average out to about 3330K 86CRI. Will produce very nice results but I would stick w 3000K myself.

      Hey Buddy,

      I am doing a first grow and was recommended by Olive Drab to use your COB lights. I initially bought two 300W Viparspectra's but i want my grow to flourish, and i realize these VP are low end.

      In a 4X2 grow tent, which light should i use of yours and how many? I was looking at the T2-v362.

      Thanks a bunch for your time

        And if u gona do cob led the whole cycle. I suggest getting a fluorescent grow light that you can stand. Vertically in the corner of your tent so the middle gets enough light

        @Boston Mike You definitely don't need HIDs for transition. Disregard that, Magus. I harvested damn near a pound using only 241w of COBs (270w including fans.)

      Do have any PAR readings of various CCT COBs? Just wondering how much they differ.

        Thanks. Actually the tables in post #9 on that page was more what I was looking for, since your figures only used CCTs up to 3500. Your post is valuable too though.

      Hi Rahz! Was told you were the man for info, can you help me out? ;)

      So I thought about 5 50v vero 29's with a HLG-185H-C700B. Seemed like an ok setup with my limited budget for a DIY project. (Tho my understanding of amp/watts/drivers, etc sucks still) I have a 3'x 4' grow tent I'm building. What exactly am I looking at... 2 plants? 4? Too under-powered to grow anything? So little understanding... ugh.

        200w would be reasonable for a 3x3, and will still be okay for a 3x4 but if you can I would get the wattage closer to 300.

        There should be a like button just below this text :)

        Same setup with a HLG-320H-C1050B

        Or if you can spend more use 2 HLG-120H-C700s with 4 cobs each.

      Oh one more question. I have been reading that with led the Room temps should be higher than hid, around 80-85 degrees. Is this true?
      1. Rahz
        Rahz
        Canopy temps should be around 85 with lights on regardless of light source. You should be able to achieve that in a tent without having the room temp at 80-85.

        Room temperatures definitely do not get hotter with COB than HID. HID utilizes heat to produce light. COB is solid state and uses electroluminescence.

      Thanks for the quick reply:) I can't wait to try out your lights! I will need to use hid lighting for the first round due to lack of money, but I will definitely order some within a few months

      I also see they are 3000k which is great for flowering but I have always used a higher kelvin rating for veg so I just wanted to make sure these will veg with nice and tight node spacing. Lastly how's the canopy penetration with these? I will be going with a scrog so plants won't be any taller than around 3 feet. Thanks for your time:)
      1. Rahz
        Rahz
        Any Kelvin does a good job in veg. The 90CRI cobs cause more stretch but the 3000Ks I will be using are 80CRI. Penetration is mostly dependent on light intensity (PPFD) My recommendations are based on a 800-1000 range which is going to provide really nice penetration.

      Hey how's it going man? I just have a couple of questions about your lights. I will be starting a new grow from scratch and have heard nothing but great things about your lights, I was also considering going with Johnson lights but I see they use older cobs so I will be dealing with you. First question is how many of the t4-2100 would you recommend in a 6x6 room for the best results?
      1. Rahz
        Rahz
        4 of them in a 6x6, the new version will be 725 PPF, so PPFD for 4 in a 6x6 would be about 860.

      The more I look at your work, the more I like it. I would like to know what would be a good light setup for 3 plants in a 4x4 enclosure. I don't plan to grow big just a couple of oz of quality bud per plant will be enough. I will LST all the plant to.

        At first I was thinking 3 T1-2100. Glad a simpler, less expensive setup will do the job. Thanks a lot.

        I have retekinded over the night and take some more mesurment. The enclosure will be 3x5. I think will better for a long light.

        Highly recommend it, Mulot. I like the idea of the T1s being separately driven at the higher amperage. Blown away by the power and efficiency of my T1, and it's well-made. I will probably be ordering a second one Friday.

      Hey Rahz. I have a 2x2x4.5 ft grow tent and looking to add an LED. I'm interested in your T2-2100. I've also looked at an Advanced Platinum P300 300W 12 band LED for a similar price. Can you sell me on yours being the superior light? Looking to buy in the next day or two. Thanks for any help/wisdom.

        email I received not long ago. "Hey bud im just finishing up a grow that I had a t4 1750 vs a platinum led p600 (100+ more watts)
        The t4 handled her own very well if not better and healthier. Ive got the p600 sold and im looking to buy 2 more T4's but 2100 series."

        COBs are way more efficient than legacy-type LEDs. They were originally designed to replace HPS in highbay warehouse applications. And I'm pushing trichomes on 2-3 day old seedlings with a T1-2100.
