Hey everyone, I have to ask this question that I am sure a lot of newcomers would like to know about lighting. I am curious from all of the information floating out there on lighting for growers, is there a good cross reference against the general watt output and their equivalents across HID, LED and CFL lighting wattage's. I did come across the attached that was pretty well put together, I think. I couldn't come across CFL cross ref. though. Has anyone, any thoughts on this one below(whole pdf attached) And has anyone have a good CFL cross ref. to add? Obviously there will be differences across manufactures however, wouldn't there be a general +/- cross ref?
