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.
