Econolight T5 4ft HO T-Bay

T-Bays are excellent replacements for HID High Bay lamps - their efficiency to cost ratio is virtually unparalleled. Using High Output ballasts, this T5 High Bay lamp system cuts conventional HID power requirements in half without affecting light levels. 95 lumens per watt with refelctors ensure an even, rectangular light emmission. Lamp life is considerably longer than conventional T8 lamps - T5s have an effective lifespan of 20 000 hours. Two configurations are possible: 4x54W and 6x54W
