    That 260 watt kit is more than enough light for either a 3x3 or a 2x4 tent. I can go to about 320 watts on 2 QB's with the driver I have, and I had to dial down to 250 watts to avoid burn. And that kit price isn't bad. Just the parts alone will run you about $250 depending on driver and heatsink - without wire or a plug or any connecting gadgets........

    I am interested in finding something square in shape that could be used to cover a 4 X 4 area....passive cooling....WARM temp 2700-3000K range -but also with an adequate amount of blue....and possible UV options???....somewhere between 400 and 600 watts from the wall....dimming capable...ready to plug in out of the box.

    Anything like that maybe coming around sometime in the near future? :)

    Honestly I've looked into UV LEDs several times and there is yet to be evidence that anything but UVB increases quality. I will give credit where it is due..... California Light Works was the first company too put t-8 UV tubes in the fixture. Followed by Amare. Until I am proven wrong florescent is still the best way to get true UVB in your grow.... Or possibly Endomaxx 150 watt cmh(which I think they discontinued). The HLG 550 Pro may be just what your looking for.

    I like the added red but in the end it probably isn't worth the added cost as the mono's are relatively more expensive.

    First of all, I want to say that I have been following this thread avidly since I started here at RIU. I am planning to get in the game toward the end of the year, and I will spend my money at HLG. Here's why.

    Yes, there's been a couple of trolls pop in and criticize HLG, Robin, Stephen, and the Quantum boards themselves. But you know what I have noticed? Not one of them has actually bought a board. The trolls can slag all they like, but the opinions that matter to me are the people that have dealt with HLG, can personally vouch for the customer service, and the performance of the boards.

    In a game like this, the focus absolutely has to be on innovation. There's a saying, "You can patent a toaster, but you can't patent toast." In other words, this concept of mounting LEDS on a larger boards cannot be protected. All it would take is a minor change and someone can completely rip off the idea, so protecting this idea with a patent would be a waste of money.

    Instead, HLG seems to be devoted to growing their business through advancing the technology. Trial and error. Different configurations. All of this consumes vast amounts of resources...time, energy, money. Despite being run ragged with these demands, Robin and Stephen take the time to ENGAGE with their clients here on this thread, and from all accounts, are very responsive to emails from their clients. They are present and that counts for a lot with me.

    There have been some inventory hiccups. But remember, these are assembled offshore, which is simply a reality in the business world of manufacturing. Sure they could have the boards assembled domestically, but that would probably triple their costs. In order to keep the prices reasonable, they have chosen to place themselves at the tail end of a LONG supply chain. The offset of the cost of manufacture is the timeframe of delivery.

    Yes, it would be nice to be able to whip up a batch of 10,000 boards overnight, but remember, this is a startup, and HLG is going through what all startups endure. They are investing their profits into bigger runs, and this takes time. I will be patient, and I suggest that others cultivate this virtue. Yes, it's frustrating to get shut out of a production run, but another should be in soon, and as HLG grows, the delays between runs will shrink, and the size of the inventory will grow.

    This isn't a matter of skipping off to Wal-Mart and picking more product off the shelves. The LED's have to be sourced, the boards manufactured, and the product assembled. Then it gets stuffed into a shipping container, and floated over the ocean. The boxes are pulled from the container and delivered by truck. ALL of this takes time. I am sure Robin and Stephen wish they had a Genie whose lamp they could rub and **poof**, a new production run would magically appear on their doorstep. But it ain't so, and will never be so.

    Anyway, this is turning into a wall of text. And it's only my second post

    Robin, Stephen. You already have my respect. Soon you will have my money as well.

    Slate 1
    Slate3 upload_2017-4-18_22-56-52.png

    20% thinner base than Slate 1. Should lower cost and offer at least same thermal performance as Slate 1.

    Slate 3 - 1 Board 310mm Length should be under 10
    Slate 3 Triple - 3 Board 890mm Length around 30
    and both come in blue

    Should 4/20 presale include Slate 3 Or a kit based on slate 3 Triple ?

    Could not have said it better myself.

    I do have quite a bit of their technology and it works so well I recently sold every HID lamp, fixture and ballast I own. I don't regret it a bit.

    Maybe you should point that towards the hlg guys there bloody good at it tbh.

    i'm using one right now with alternating rows of 3000K and 5000K leds, my reasoning being that it will give me a balanced spectrum, not making little shrubs, or big stretchy beanpoles. seems to be working so far, getting just as much growth as i got with the 250watt MH and t5 combo i was using before, with a lot less heat to deal with, at about half the power consumption, and the plants are nice and full, stalks bigger than my thumb at 1 foot high

    Its nice YOUR using one but that doesnt help tstick does it? how about some info like where you got it? how many diodes in 3k and 5k?, Who made it? and will he make more?
    are the 3k and 5k in dedicated channels to be contolled by separate controllers and or drivers?

    QuarksRSmall Well-Known Member

    Both options would appreciated on the next pre order. It appears that anything that you would like to offer concerning these boards, will be scooped up almost immediately. Ignore the naysayers and keep stepping up to the plate to take your swing. You are batting 1000% at the moment.

    i got it off my friends workbench, i bought the leds from digikey, half
    and the other half
    my friend Gilford made it, and right now he's teaching me to make them myself, so i'll quit bugging him to do it for me.
    they are NOT set up on different channels, they all run off the same buck converter, set to 4.5 amps and 44 volts.
    my set up is a little more captain caveman than most, and these are basically the same chip in two different K ranges. its not causing me any problems that i'm aware of, i don't have a good meter, just an old lux meter, but they seem to all be operating as they ought to, when they're all on, you can't look at it and see any difference.

    just bought 500 more
    planning on making a 4 panel QB to flower one plant under. planned to do this already, with the light i'm using now for veg but shit happens. if it works well, i'll make 4 more of them and get rid of my 600 watt hps, run my whole flower tent off of them.

    as soon as i can solder them to the board without melting them and burning my thumb....

    How many spare volts on hlg240-1400 with 3x qb288 on? i wonder if i can add more boards or monos..

    The spec sheet for that driver shows 179V. Not enough for a fourth board in series, however you can run 2 sets in series and then use parrallel to connect the sets to the driver.

    Check the specs on the monos. There aren't many that can tolerate 1.4 A.......
