T8 - still stuck in the 1900's?

Still using the old 1" T8 size? Use T5 (16mm 5/8") with superior flicker free light output that uses 40% or less power. Simple Retrofit Upgrade with adapT5 Power Savers

T5 HO fluorescent lamps produce their maximum luminous flux at 35°C, compared with 25°C for old T8 fluorescent lamps with a tube diameter of 26 mm. Since the temperatures in the luminaire are higher than the ambient temperature of, say, 20 to 25°C, the efficiency is at least 5% higher than for old T8 fluorescent lamps. The small tube diameter of 16 mm also leads to an increase in the efficiency of the luminaire. These lamps offer even more luminous flux if they are operated within the luminaire at their optimum ambient temperature. Excellent for energy saving replacement of old HID lamps where high light output is needed.

T5: 14W, 21W, 28W & 35W
T5HO: 24W,39W, 54W and 80W
