Philips Lighting 51 W T8 Fluorescent Tube, 4800 lm, 1500mm, G13

Direct retro-fit to replace standard T8 fluorescent lampsWorks with both magnetic and high frequency ballastsLatest highly efficient phosphors and filling gas produce comparable light outputsSaves in excess of 10% of the running costsBased on 20,000 hours ruin time (HF ballast) the 5ft tube will save 140kWh of electricity, and the 4ft tube saves 80kWhTriphosphor coating gives good colour rendering

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.

Nominal tube diameter - T5=16mm, T8=26mm, T9=29mm, T12=38mm
