Space wise is about 0.72m^2, the 200W verison is good for about 0.64m^2.

Hi all!

Has anyone ran these lights and could offer a comparison? or anyone that knows their stuff about lighting units. I've read positive things about the ViparSpectra but the Lumatek is supposed to be built incredibly well and also a really effective light.

Space wise is about 0.72m^2, the 200W verison is good for about 0.64m^2. The ViparSpectra 450W is good for 0.37m^2. Obviously the 450W is more than twice the 200W but in terms of actual performance, which is gonna come off better?

Thanks in advance!

Sure those aren't backwards? Seems like the higher wattage should cover more area, unless the 450W is just a fake number and it really draws less.

According to my math, you will want about 270 watts to cover the 7.75 sqft (0.72 sq m)

so a 300W full spectrum would be the ideal size and power for that grow space then?

You can always use a higher wattage light and dim it back to about 270 watts using a killawatt meter or other means.
