    Just want to add some useful info.
    The sunmaster 600w produced 1,500 more lumen compared to the omega 600w I had. (Sunmaster 6,700. Omega 4,500)

    I'm a bit confused, my 600w lumii blk says 88,000 lumen and the sunmaster dual spec says 90,000 lumen? How come such a difference?

    My lux meter is a pretty cheap one snd my readings were taken from my canopy level.
    If you look at my incredible bulk scrog diary from this time last year. I think half way thru veg you can see the difference

    Two to three percent difference between manufacturers & bulb specs is a little neither here nor there

    My LAGarden had A better PAR spread than the Genesis or the Hortilux.

    Philips Green power dual spec are used in the growing industry, the bulb is designed for horticulture use, sylvania grolux are also good dual spectrum at a much lower cost, personally I change grolux for each crop and green power every 2nd crop.
    The difference between the top end bulbs and more budget isn't a lot it's said, let's say 10% that's 50 grams over 500g or nearly 2 ounce £500 in old money imo that's a cheap 2 oz.
    If you're only growing smaller amounts it might not be worth it to you but imo it's a investment.
