Easily fitted in place of T8 tubes. Economical tube with long lifespan (approximately 42,000 hours). Recommended for hard-to-reach areas due to their low rate of premature failure, such as tunnels, airports, underground systems, mines etc. Colour: "cool white", with a temperature of 4000 K. Tube diameter: 26 mm.
Fluorescent Triphosphor
Triphosphor tubes have longer life, a lower mercury content, better colour rendering and higher lumen maintenance than their Halophosphate counterparts. The tubes are available in a variety of colour temperatures from 3000K (warm white) to 6000K (daylight).
Extended life expectancy which can be increased by upto 20,000 hours with the use of high frequency luminaires. Shatter resistant versions available which retain the fragments in the event of a breakage. Option of triphosphor tubes with internal reflectors, which reduce waste light and increase light output by up to 75%. 16mm (T5) tubes provide a compact alternative to T8 tubes, offering peak performance at +35 °C and typically provide 5% more efficiency in most ceiling applications when compared to equivalent T8 tubes.
