What Dutch said. :thumbsup:

I've also have seen that alot of Euro grower's refer to the CFL bulb size by the "incandescent equivalent" wattage, where as most American's refer to the wattage the bulb actually uses. For example on another thread someone said, I have 100w of CFL when inreality (my reality) it was a 23 watt bulb. Big difference.

Also I think that American grower's use Kelvin temp of the bulb rather then vague terms like "warm white" or "cool white". I'd rather know if a bulb is 2700k or 6000k, the first good for flower and the later is good for veg.

But what do I know, I'm an internet heritic.
