Don't seem`s too bad, but its a lot of Watt in one small Panel, thing with LEDs, beside they make next to no heat

is that they don't spread the light out much
nothing like a HPS, the LEDs is pretty one directed, I would try and find two smaller fixtures or even 4 UFO`s (good quality not the cheap E-bay chinese once)
I run two fixtures in a 90x120 space



one is a 120x3W with a actually watt output on 288 (the LEDs run at 2,4W) and it have double/secondary Lenses on (cost about 440 € here:

other one is 96x3W who run its LEDs on 2W so it put out 192W with no secondary lenses on it (was on sale for 280€ here:

Im in Denmark and like to shop in EU so I don't have to get it shipped over sea and pay vat/taxes, often end up at the same price as ordering from the US even china but I like to avoid them for other reason (like bad quality and the fact that they kill our middle class, but thats another story) tho most of the panels is most likely made in China to start with
go for quality, not just do you often get what you pay for, but its not like your going to buy a fixture every months, so do pay the extra bucks and get something that works to start with and safe your self some headaches
