    ive looked just about everywhere. even direct from china after shipping and everything most places are within a few bucks of each other unless youre ordering a whole lot of them and picking up at the port. the only reason to go outside the box and order from a non sponsor is if they just dont have it or back ordered etc. i just looked at some of my save quotes from alibaba and the drivers were within $2-20 of what the vendors sell them for but after international shipping you are paying the same if not more on small orders.

    i got a nice quote for heatsinks until i saw the shipping was $185 for 32 of them :( which put them at the same exact price as most vendors.

    Is there a thread about the new generation citizens? Where the information isn't buried in 70+ pages lol.

    Will do, looking to get started again in April. Two HLG-320H-48A would push 820 watts, correct? I don't want to bust out the datasheets if I don't have to.

    i think they come up on 400 depending on cob voltage

    not much to report

    same sizes
    same nominal voltage
    few % flux increase
    slight Tj-c improvement
    higher allowable Tj and Tc

    overall about 3% relative bump per datasheet

    Oh right. Yeah I've been running Cree xte royal blues and xpl 6000k monos in mine for a bit over a year. Something isn't right. Was getting weird growth and what lookz like a phosphorus lock out when the temps get too cold. So have been changing humidity and fan counts and intake air and anything I could think of. Anywayz...veging a couple of seedlings under my Citizen COB build (3500k) and the results are completely different. Awesome green growth, quicker sexing, just a more mature stronger plant....really weird and unexpected that a combo of colourz would do this to plant.. (shrug?)

    So I like the 4000k 80 CRI idea...thanks :)

    I'm using a HLG-120H-48A driver. No multimeter here (and not planning on buying one), I'm just not into DIY. In laymans terms, where should I have the adjusters if I want the light running at around 75% power? Should both adjusters be kept in around the same position?

    buy a $5 multimeter you'll be glad you did.

    otherwise a watts up is useful to measure wall power

    turn Vo all the way clockwise and adjust with Io
