Fluorescent Tubes

General information and pictures for the product group: "Fluorescent Lamps"

First choice for durability.

Fluorescent lamps produce 70 percent of artificial light throughout the world. For economical reasons they are the first choice for many applications because they combine high luminous efficacy with low power consumption. A LUMILUX fluorescent lamp, for example, needs only around 15% of the electricity that an ordinary light bulb needs. The average life of a LUMILUX T8 is 20,000 hours, whereas an ordinary light bulb will last only 1000 hours.

Environmentally friendly.

Low power consumption and long life mean that fluorescent lamps are kind to the environment. Their recycling quota is another plus for the environment. More than 90% of the weight of an OSRAM fluorescent lamp can be reused for manufacturing lamps and 5 to 10% can be used in the manufacture of other materials.

White, white, white or white

White comes in different shades.

OSRAM fluorescent lamps are available in up to seven different shades of white: SKYWHITE (8000 K), Cool Daylight (6500 K), Daylight (5000 K), Cool White (4000 K), White (3500 K), Warm White (3000 K) and INTERNA (2700 K). But which of the seven is right for which application?

Choosing one or other of the shades is a matter of personal taste, individual perception and local preference, and a question of the atmosphere to be created. Cultural influences should not be underestimated. People in northern Europe prefer warm white, while people in southern Europe tend to choose cool white.

The environmentally friendly LUMILUX lamp.

LUMILUX fluorescent lamps from OSRAM are now even kinder to the environment. Most T8 lamps now contain only 3 mg of mercury. Most T5 FH and FQ lamps only contain 1.6 mg of mercury - so they fall far below the RoHS threshold of 5 mg. Thanks to the high energy efficiency and long life of these lamps, consumption of raw materials and emission of CO2 can be reduced.

How a fluorescent lamp works.

Fluorescent lamps are gas discharge lamps. The glass tube is filled with mercury vapour under low pressure. The inner wall of the glass tube is coated with a phosphor that reacts to ultra-violet light. At the ends of the glass tube are electrodes. When an electrical charge is passed between them the mercury vapour emits UV radiation. This radiation is converted by the phosphor into visible light. The colour of the light varies according to the phosphor used.

Smaller size, greater efficiency better performance: the economical LUMILUX T5 HE system.

HE stands for High Efficiency. With a tube diameter of only 16 mm, these lamps offer an extremely high luminous efficacy of up to 104 lm/W. They are designed for ECG operation with cut-off and are up to 20% more efficient than T8 lamps. This system and the compact ECG means that extremely slim luminaires can be created. They are 50% smaller in volume and 5 cm shorter in length, which means they fit perfectly in 60 and 120 cm louvered ceilings.

The particularly bright LUMILUX T5 HO system.

HO stands for High Output. This lamp system is particularly noted for its high luminaire efficiency due, among other things, to the small tube diameter. The FQ 54 W HO, for example, with a length of 1149 mm and a diameter of 16 mm, offers the same luminous flux as a T8 58 W lamp with a diameter of 26 mm and length of 1500 mm. HO lamps are designed for ECG operation with cut-off and are much more economical.

The universal T5 HO CONSTANT system.

HO CONSTANT is particularly suitable for cold applications (for example outdoors) and for hot luminaires (narrow recessed luminaires) because it provides more than 90% of its maximum luminous flux in an ambient temperature range of + 5 °C to + 70 °C, thereby extending the previous temperature range by 20 °C.
