using for veg

250 watt CFL

Of course it's bigger, it's a totaly different kind of CFL. That CFL you are reffering to is an actual 250watts, that's why it's so high in lumens. The 300watt store bought CFL is an actual 68watts.

I do prefer the CFL you are reffering to but the other types are much easier to relocate around the grow.
