T-5 HO fluorescent lighting vs. pulse start metal halide
T-5 HO fluorescent lighting vs. pulse start metal halide
(OP)
Ceiling height of 35-40 feet.
I was thinking about replacing existing 250 HPS (25,000 lumens) with 200 watt pulse start metal halide (20,000 lumens) in an open bay building or a t-5 HO (15,000 lumens)with 4 4-foot bulbs. What are the nominal fixture efficiencies? Which is best as far as color rendering index and energy efficiency for these given heights for equal footcandles.

Regarding the color rendering mentioned by hbendillo, there are newer ceramic metal halides out there, I believe they have a better CRI than most fluorescents.
