I believe the correct K's for a CFL for proper growth is a 'daylight' bulb, which's 6500K, so probably not, and even an energy-saver ..@ 8W might be a bit on the dull side for sustained growth.
Be fine as a supplimental light if you're using something else, but I wouldn't be using one 8W globe for an entire plant.
Good news is, you can buy "daylight 6500K" CFLs for $8 earch, so it's not hard to replace it
..They also sell Growlush CFLs that use-up about 150W, and pump out a massive (comparatively massive) 8,000 lumens. Standard household SFLs only put-out around 1,000 lumens.
All about the lumens really
The indoor 'standard' 400W HID lamp pumps out a staggering 50,000+lumens - on average, so you want to get as close to that as possible with CFLs.
All this is chicken feed compared to the "real" standard in lighting: The sun. It pumps out so many lumens that plants on earth can't even USE ALL the light the sun lays down on em.
I wouldn't have a clue how many lumens the sun emits, but I'm guessing a shitload more than 50,000
But if your globe's in that 1,000 lumen range, then you're going to need more than one of em, tis for sure.
