THAT bulb is a foot long, and about 5 inches wide, draws 105 watts, and puts out nearly 7000 lumens

great bulb if you have the space, just realize it's the BIGGEST CFL BULB YOU HAVE EVER SEEN.

the bulb will draw 105 watts ACTUAL electricty, which is EQUIVALENT to about 400 watts of INCANDESCENT lighting.

they do the confusing "wattage comparison" so the average housewife can choose the appropriate CFL conversion from incandescent lighting, but I agree with you, it's just confusing when trying to choose ACTUAL wattage numbers.

Home-De-Pot has that bulb for under $15.

Even more confusing when you read posts about 230 watt cfl grows.

I agree you should look at the "real" wattage of 105w as this is the number everyone uses in comparing grows/specs. Just an FYI, that "real" wattage is still not the real wattage at all! CFLs are very inefficient so it's probably using something more like 140 ish or more.

If any CFLs are lying around and list the amps, you can check that for yourself: There is a law that states watts = amps x volts so type in your amps and volts and see what you get. Other fluoros like pl-l or t-5 have much higher efficiency ballasts than CFLs and as such are a far better choice.

By the way even that is not the true real wattage but it's close enough

haha ok thanks guys glade i checked things by posting! im looking for a bulb that would grow a single lady in my pc micro grower and this bulb i posted is defiantly not the one for me.. i only have room for a single bulb unfortunately im broke and only have the resources at hand. however from the info iv gathered here il need a bulb that emits something equivalent to 100watts? thanks for all the help iv always wanted to try growing nice crops under a light having always been an outdoors grower subjected to living in a climate that is not always the greatest for high end nuggs to develop.
