Dimming amalgam lamps
- Shorter start-up due to Power Boost
- Optimal lamp operation even at low dimmer settings
Amalgam
T5 fluorescent lamps HO CONSTANT, as well as compact fluorescent lamps OSRAM DULUX L CONSTANT and OSRAM DULUX T/E CONSTANT, show, thanks to amalgam technology, constant high luminous flux over a wide temperature range.
More efficient and energy-saving lighting for T5 and compact fluorescent lamps.
Compare:
- Conventional T5 lamps:
> 90 % luminous flux between approx. 25 °C and 50 °C (max. luminous flux at 35 °C)
- CONSTANT lamps:
> 90 % luminous flux between 5 °C and 70 °C
(except LUMILUX T5 HO 49 W CONSTANT: 20 °C and 80 °C)
Your benefits
- Flicker-free pre-heat start
- More light than from conventional HO lamps
- Higher system efficiency over a wide temperature range

The amalgam releases just as much mercury as used for the discharge phase and reduces therefore the decrease of the luminous flux at high or low temperatures in a tremendous way. After a change in the operation mode, it takes several minutes until the mercury balance is set up. When the lamp is switched off for a longer time – no discharge, no mercury demand – the amalgam gathers again the whole amount of mercury. During a restart, there is at first a lack of mercury, being visible by the “pink-phase.”
