With bulbs? ... oh wait, I was pricing the "T5" fixtures and wishing for high output bulbs. Those might be 50-75% more expensive than old-style (T12?) shop lights.
But more efficient and more concentrated.
I see clearly that my CFH screw-in arrangement is not so good for the plan ts farher away from the bulbs. But I figured that the "equivalent" of 500 W spread over 8 squrre feet might make up for the distance.
Aren't old-style tubes considered to be equivalent to around 1 W per linear foot? so maybe 80 W per 48" tube? If that's true, my haphazard setup might be the equivalent of 12 T12 tubes, just not distributed as uniformly.
I know I should try to fiogure and comopare "lumens" but i don't have even rough numbers for those.
