we have a new indoor riding arena we just had built, now looking at lighting to mount on a steel ceiling. Looking at T5 vs LED lights. would like to know about mounting the T5's flush because of the heat they put off. Also some are 4,000 lumens some are 20,000 lumens Do the lumens change when comparing LED vs T5's How many would you suggest for the building 100' x 216' 515-314-3310
