Narva 58 W T8 Fluorescent Tube Yellow, 1500mm, G13

The Narva LT-T8 YELLOW Special fluorescent tube lamps have an average life of 20,000 hours if operated with electronic warmstart ballast. These tube lamps feature a special phosphor and an additional phosphor layer, which ensure that the spectrum of the light colour YELLOW Special contains wavelengths larger than 500 nm only, which is visible as yellow light. These coloured fluorescent lamps are used in rooms where no UV or blue component is allowed in the spectrum. The yellow light is invisible to many insects; therefore ideal applications of the LT-T8 YELLOW Special fluorescent tubes are in areas requiring to be free from insect.

Light wavelengths larger than 500 nm only
Yellow light does not attract most insects

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
