Fluorescent lamps

Fluorescent lamps produce 70% of artificial light throughout the world. Their excellent economy and eco-friendly characteristics make them the first choice for many applications. Fluorescent lamps combine high luminous efficacy with low power consumption. A LUMILUX® fluorescent lamp, for example, needs only around 15% of the electrical power that an ordinary light bulb needs. In terms of their lifespan they are also an excellent alternative. The average life of a LUMILUX® T5 HO is 24,000 hours, and that of a LUMILUX® T8 20,000 hours - compared with just 1000 hours for an ordinary light bulb.

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 our fluorescent lamp can be reused for manufacturing lamps and 5 to 10% of the weight (e.g. metals) can be used in the manufacture of other products.


First choice for durability.

LUMILUX® fluorescent lamps from our company are increasingly kind to the environment. The T8 LUMILUX® lamps now contain only 3 mg of mercury, and the LUMILUX® T5 HE and HO lamps only 2.5 mg - so they fall far below the RoHS threshold of 5 mg. In systems with ECGs from our company these lamps make an ideal contribution to environment protection - not only because of the very small quantities of hazardous substances but also because of their very high efficiency and long reliable life (with consequently lower consumption of resources). They are also perfect for combining with daylight dimmer systems and presence detectors. This leads to even greater energy savings.


How a fluorescent lamp works.

Fluorescent lamps are low-pressure gas discharge lamps. The glass tube is filled with an inert gas at low pressure and a small quantity of mercury. The glass wall is coated with a phosphor. At the ends of the glass tube are pasted electrodes. When an electrical charge is passed between them the mercury vapor emits UV radiation. When the UV radiation hits the phosphor the phosphor emits visible light. The color can be varied for different applications by selecting different phosphor mixes.

 

The long-life LUMILUX® T8 XT and XXT systems.

The new LUMILUX® XT and XXT product families are the ideal solutions for all applications in which relamping is a difficult, time-consuming and therefore costly operation. The service life of the XT lamps on a preheat start ECG is 42,000 hours (switching cycle 11/1), and the XXT lamps can remain in use for as long as 75,000 hours until they reach the recommended relamping time. Because of the low loss of light of LUMILUX® T8 fluorescent lamps the service life of these lamps is defined as the time when 10% of the lamps have failed. We recommends replacing all the lamps at once at this time in order to save costs. Resources are also saved because a LUMILUX® XXT lasts so long that it replaces 4.1 LUMILUX® lamps.

 

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 (at 35 °C). They are designed for ECG operation and are up to 20% more efficient than LUMILUX® T8 lamps. They also enable extremely slim and compact luminaires to be created because their volume is up to 50% less and their length 5 cm shorter than comparable T8 lamps.

 

The particularly bright LUMILUX® T5 HO system.

HO stands for High Output. This lamp system is particularly noted for its very high luminous flux, opening up new areas of application for the fluorescent lamp such as lighting for high-ceiling rooms. The T5 HO 80 W/840 for example has a luminous flux of up to 7000 lm (at 35 °C). HO lamps are designed for ECG operation and, like all LUMILUX® lamps are ideal in systems with motion sensors and/or daylight dimmers to reduce energy consumption to a minimum.

 

The universal T5 HO CONSTANT system.

HO CONSTANT is the first fluorescent lamp that has been optimized for a wider than usual temperature range. It 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. Efficient energy-saving lighting is now possible in new areas of application.
