    Default Unanswered: Upgrading my lights - help!

    So I'm upgrading my blurple 600w Chinese unbranded led with a new Quantum Board! Excited is an understatement!

    I'm confused about the variants tho because I'm clueless with anything scientific/ lights related!

    I've settle on the 240w Kingbrite Quantum Board but....

    Do I go for

    A) 3000K+660nm
    or
    B) 3500K+660nm

    My tent is 900x1200 between 2 and 4 plants usually. I also have no idea what A or B means

    Any advice would be amazing you beauties!

    Swapping cheap Chinese... for cheap Chinese!

    It ain't a quantum board mate, Quatum is a trade mark of HLG - cheap Chinese forgeries

    Haha ye I'm totally with you mate but the saving is unreal and the reviews seem good.

    My goal is really size rather than improving quality, I'm getting good results from what I'm using but the unit is too thick (about 6inches top to bottom) restricting my height and I like the idea of it also being dimmable!

    looked into this myself and came to this conclusion..

    3000k = mainly for flower (equiv HPS)
    4000k = mainy for veg (equiv MH)
    3500k = all rounder (equiv Dual-Spec HPS)

    HPS is more like 2100K or even 1700K

    Bear in mind the 660 will reduce the overall kelvin of the light. Id go for 3500K or 4000K if they have it.

    If theres any option for 80 CRI or 90 CRI, go for 90

    agreed.

    and yes, hps is closer to your numbers. but of the 3 options generally available, i matched as close to their equiv as possible.
