Osram 35 W T5 Fluorescent Tube, 3300 lm, 1450mm, G5

This range of fluorescent tubes from Osram are a standard T5 size. They are tubular with a diameter of 16 mm and a G5 base. These T5 fluorescent tubes have a long average lifespan of up to 24,000 hours when used with Quicktronic ECGs.
Osram T5 fluorescent lamps offer decoration and illumination in a cost efficient package. They provide excellent luminous flux maintenance throughout their entire lifespan, meaning that the bulb will not become dimmer with repeated use. They also have good colour rendering and are dimmable.
Fluorescent tubes give off a brighter light than halogen bulbs. They have low running costs and a long lifespan so no need to worry about replacements making them suitable for a number of applications. When choosing a fluorescent tube the number of lumens (Im) is important as the higher the number of lumens the brighter the bulb will be. T5 fluorescent tubes also produce high levels of colour rendering and efficacy.

Fluorescent tubes contain mercury so you most dispose of these tubes safely as per regulation.

FAQ:
Which colour temperature to pick?
Fluorescent tubes are available in a variety of colour temperatures which describes the light appearance provided by a light source. It is measured in degrees of kelvin (k) on a scale from 1,000 to 10,000:
2700 – warm white – ideal where relaxing and ambience lighting is needed
4000K – cool white – lighting ideal for a kitchen
+6000K – daylight – very sharp, lighting ideal for a working environment

Which cap size?
You need to have the correct cap size:
2Gx13 (U-shaped)
G13 (T8 and T12)
G5 (T5)

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
