Don't worry about electrical load. All of my bulbs combined was 388w - compare that to my space heater which is 1500w and it's nothing. I want to say my desktop computer pulls 400w and is never turned off.
If you are worried about cords id suggest something like this - you can't place individual bulbs as ideally as possible but I purchased 3 of these for $3 each, add Y connectors and you can do pretty much anything. The ugly while part can be stripped down to reveal just a steal strip and the bulbs and you can easily make a decent reflector out or mylar, foil, aluminum ducting...
I had a 1x1x2' cab with 2 23w CFLs for veg where I would germ seeds/root clones - it held ~36 small seedlings, 16 fresh cuttings, 12 rooted cuttings, 9 medium clones, or 4 young teens. This allows for a straight 12/12 perpetual in the flower cab.
My 2x3x4' closet space held 6 fully mature plants or several more if there was a mix of age. I would have 6 plants in different stages of full flower (2+weeks) in my main flower cab at a time and 2-3 plants just entering flower - with individual bulbs I was able to vary the canopy to maximize growth of all plants at all stages of development.
With 8-9 plants in the cab at a time at a staggered rate and harvesting each plant at 7-9 weeks of flower that's one oz a week.
Pots were 1 gal.
