I wouldn't trust that LED bulb as far as I could throw it. Keep in mind that not all LEDs will grow plants.
Make sure when counting your CFL wattage, that you count the actual wattage used. Do not count the "Incandescent equivalent" number. This number is there only to help peopple select a new energy saving CFL bulb to use that will be a similar brightness to their old incandescent bulb. And since incandescents cannot effectively grow Cannabis, this number is useless for our purposes.
And keep in mind as you're pricing all this stuff out.... a good LED grow light starts at like $80 from our
sponsors. So if your CFL costs, light fixture costs, wiring, etc.. start to hit that area, you'll be better off buying an LED.
I already grew with CFLs. My last grow was a 361 watt setup with 14 bulbs. I upgraded to an LED that covers 3.5x2.5 feet, is stronger than my CFLs, and uses less than half the wattage as my CFLs (uses 150-170w total). So you'll save on the power bill as well.
