Does anyone use fixtures with T5H tubes/bulbs?
I just installed a couple of 4', six tube fixtures, and Holy Cow, what a difference in light intensity from my standard 6500K fluorescent fixtures. A comparison, at least the best I can do, is saying the cumulative light from four, 4', two-tube T8 fixtures would give the foot candles of a cloudless day at 4:00 PM and the light from a single, 4', six-tube T5H fixture would give the foot candles of a cloudless day at noon. Actually, the T8 bulb would emit 2900 lumens and the new T5H bulb would emit 5000 lumens. The difference is just remarkable.
It will be interesting to see whether I can tell any difference in my orchids' growth/blooming, since both new fixtures are in my Orchid Greenhouse.
