good info here late .. nice thread :thumbsup:

let me just add that CFL's often have 2 ratings on them... the REAL wattage, and the wattage equivalency of a incandescent.... the 150w cfl you get in the store is not a 150w, but a 42w or 45w that puts out as much light as a 150w incandescent... the 125w CFL's (like envirolite) need to be bought at a garden store and require a mogul base, where normal CFL's will go into any normal light socket

also, you didn't cover why incandescent lights suck

basically, they produce more heat than light per watt, and that can be difficult to control temps in a closed space... plus they just waste electricity because of that... a CFL puts out way more light with way less electricity, and can be bought in cool (blue) or warm (red) white :twocents:
