Narva 36 W UV Light Bulb G13, length 1.2 m, Dia. T8, 55000h

The Narva LT-T8 BLACKILIGHT Blue UV Radiators have an average life of 8,000 hours if operated with electronic warmstart ballast. The blacklight blue light colour of these tube lamps generates long wave UV light. These UV radiators feature black glass, which ensures that practically no visible light, but only UV radiation comes out of the tube lamps. Ideal applications of these fluorescent tubes are in material analysis (hairline crack tests), checking bank notes and stamps or fluorescent effects in discotheques.

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
