LED modules are operated via special driver network components that are optionally equipped with standardised interfaces. This enables simple continuous regulation of brightness. Additional high cost controller components for dimming are not needed.

The efficiency of a luminaire with LEDs is to a high degree dependent upon the optical system and thermal management of the LED modules. If this is ensured, LEDs offer a good alternative to compact fluorescent sources. When comparing total costs, the long service life of LEDs should also be considered, including the associated advantages with regard to extended maintenance intervals.

Negative burdens due to emission of short wave radiation is not possible with LEDs. But with light control or shielding that is not optimal, the very high luminance values of the light sources are noticeable. In this respect, construction engineers should place special emphasis on compliance with maximum illuminance or luminance values.

TRILUX is obliged to ensure the environmentally-friendly disposal of its luminaires.
All TRILUX products are correspondingly designated according to the 2003/108/EG directive for environmentally compatible disposal. For this a contract with the company of Interseroh has been agreed that assumes the subsequent disposal of obsolete TRILUX products from commercial customers. In the UK TRILUX is registered with the Lumincom Compliance Scheme (Reg.-No. WEE/KH0108WX) for the safe disposal of all obsolete luminaires. TRILUX products stocked at wholesalers are already deemed to have been delivered. Private devices however must be disposed of via the local material disposal collection points. Usually this is free. TRILUX according to the electrical legislation (ElektroG) is registered with the responsible government office EAR ('Stiftung-Elektro-Altgeräte-Register') with the following registration number: WEEE-Reg.-No. DE 15415083.

In the outdoor luminaire sector that has already been partly achieved, for example with the 93 series. We are ascertaining successively which further luminaire series are suitable for retrofitting in terms of geometry and thermal management. Installation of our refurbishment sets is done quickly and simply, and therefore also with low cost. The safety designations (ENEC and radio interference designations) are also valid following upgrading.

Dimming of metal halide lamps with ceramic burners and high pressure sodium vapour lamps is fundamentally technically feasible. But to ensure safety and functionality, some important points must be considered:
1. Use of suitable, controllable electronic ballasts (in short: ECG).
2. In order not to endanger lamps, the lamp should be dimmed to max. 60%. Effects on the service life of the lamps are not specified.
3. To ensure correct burn-in of the lamps, they must be operated for at least 15 minutes at 100% output. Reduction of lamp output may then occur.
4. With metal halide lamps, colour coordination shifting during dimming must be assumed, and so it makes sense to check beforehand whether the desired light colour can be achieved.

Yes, LEDs can be dimmed from 0 to 100 % luminous flux. Luminous flux and consumed wattage reduce linearly. Simultaneously, service life increases and luminous flux decline over the service life lessens. For LED systems with dimming/colour variation, special control units are needed, controlled via DALI or DMX.

According to DIN EN 1838 (July 1999 version) the following is specified:
"To achieve the requisite safety for evacuation purposes, illumination of the room is required. With this standard the recommendation is complied with when luminaires are installed at least 2 metres above the floor."

Standardisations for LED modules are desirable. But for this LED manufacturers, LED module producers, luminaire manufacturers and the manufacturers of the required electronic operating components must work tightly together to ensure for the customer better comparability and replaceability for the future. In regard to this, TRILUX is working together with the Zhaga standardisation project.

Yes, it is possible in the 9721SG/400HST... luminaire to fit a 400W HIT lamp instead of a 400W HST lamp.
