Today i got my T5 light fixture that i order a few days ago, i've been playing a lil bit with it and i have put most of my plants under it. The fixture is 4 feet long and it holds 8 bulbs. I've been reading the light with my light meter and so far my plant are getting:

Phals, paphs(mottled leaves) they get between 1700-2000 footcandles
Neofinetias they get between 2000-2400 FC
Oncidiums and hybrids they get between 2300-2700 FC
paph (strap leaves) and phrag they get between 2700-3300 FC
dendrobium they get between 2800-3300 FC
Cattleyas they get between 3000-3600 FC
Vandas they get between 3500-4100 FC

The lights stay on for 16 hours straight and on top of that they get really bright light and some full some in the morning from like 7-11. If i were to measure this light in the morning they all get about 2000-2500 FC for 4hours plus the light from the T5 fixture.

Do you guys think this is enought light or not enough or too much or some of them are getting the wrong light????
