Hey DA
Been thinking about your problem.

If youve got 80w cfls youre going to have plenty. Youre just looking to extend your daylight period to extend your veg period right.. Not use the light to grow youre plants. Blue spectrum light i think is more effective. So i hope those cfl are cool white.

Im old school so i think foot candles.
From my experience i think you only need about 20 foot candles - roughly 200 lux to restrict flowering hormones. This is the minimum light required so more is better.

A sunny day is 110,000 lux the moon maybe .2 lux.

Id get a cheap lux meter- position one of your lights and back off till your lux meter is reading around 200lux. Measure the distance to the light. Double it. Thats the maximum distance your light centers can be apart. Its probably plenty more than you need for 2 BIG plants per light.

Closer the better... Some plants are more sensitive than others.

Good Luck

If you extend the morning, rather than the evening, you will see the plants wake up with the lights. Outdoors, They get up with the sun. Perhaps an hour late on a cloudy day. It really doesn't take much.
