T5 LED Tubes
Until recently it was impossible to replace T5 fluorescent tubes by energy efficient alternatives. Recently however both Osram and Philips have introduced T5 LED Tubes that yield about 50% savings. The Philips product is the MASTER LEDtube InstantFit HF T5, the OSRAM products are OSRAM SubstiTUBE® Advanced T5 and T5 UO. 49 Watt T5 tubes can be exchanged simply, without fixture changes. The Osram T5 UO tubes can even replace 80 Watt T5 tubes.
