Product Details

Osram Luminux HO Fluorescent Tubes

The Osram Lumilux T5 HO series of fluorescent tubes are high output. They have a very high luminous flux and are designed for ECG operation. These fluorescent tubes are ideal in systems with motion sensors and daylight dimmers and can reduce energy consumption.

They meet standard T5 sizing and feature a 16 mm diameter, with a G5 base. Lumilux T5 HO fluorescent lamps are dimmable and offering good colour rendering (falling in the 1B group for colour rendering).

This range of high output fluorescent tubes can achieve an average life of up to 24000 hours and a service life of 18000 hours when used with hot restart ECGs.

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.

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


• Dimmable
• Excellent luminous flux
• Good economy and efficiency
• Up to 20% more economical than Lumilux T8
• Up to 50% smaller volume than comparable T8 lamps
• Natural colours
• 90% lumen maintenance through service lifetime
• Average lifetime up to 24,000 hours

Product Applications:

Fluorescent tubes and lamps have always been popular in the workplace and at home as they are both cost effective and energy efficient. Some areas where fluorescent tubes are used are:

• Industry
• Public buildings
• Offices
• Car parks
• Tunnels
• Underpasses


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


  • A lamp breaking is extremely unlike to have any adverse effects on your health. However, if a lamp breaks, you should ventilate the room for 30 minutes before removing the parts (preferably with gloves on). The parts should be taken for recycling at your local waste facility.
