I thought this might come in handy to other people.
I recently changed the lights I had for some of my orchids (shoplight fixture with 2 4ft T8) to T5HO (3 bulbs).
Here are the light measurements at 23 inches from the bulbs, in the middle.

2x4ft Philips Alto (5000 K, 32W) - 1650 lux (153 footcandles)
3x4ft Sunblaze T5HO (6500 K, 54W) + reflector (95% reflective) - 7900 lux (734 footcandles).
