Approx. 900 watts of CFL. probably less due to age of the bulbs. but either way.. that much is what i've been using for 2-4 plants.

so no, 80watts won't cut it.

Depending on where you are and what kind of money you're willing to spend. you can lights like these..even better ones online.

these were 14$ canadian. not bad all things considered.
lights!
