LED light engine: Ergonomics meets freedom of design, TALEXXengine STARK INDI for direct and indirect light

Tridonic is launching TALEXXengine STARK INDI, an LED system that produces uniform light for both direct and indirect illumination. The light is directed downwards and upwards in a ratio of 80% to 20%, or vice versa. With its slim low-profile form the LED system gives designers enormous freedom and can be used as a replacement for T5 and TCL lamps. Its main applications include offices and educational establishments.

TALEXXengine STARK INDI is available in the CLASSIC version with a CRI greater than 80 and is ideal for floor-standing and pendant luminaires. The indirect portion of the light provides uniform background illumination, while the direct portion offers efficient desktop lighting. In a pendant luminaire 80% of the light is directed downwards and 20% upwards. These proportions are reversed for floor-standing luminaires. The impression is always of uniform area lighting because the combination of side edge injection and special diffuser materials means that individual points of light cannot be seen.

Precise planning
The LED light engine is available with colour temperatures of 3000 K and 4000 K. A special feature is the highly reproducible white light quality (MacAdam 4). Withy dimensions of 564 x 100 x 8.5 mm the modules also fit in luminaires previously equipped with T5 lamps (2 x 28 W, 2 x 35 W) or TCL lamps (2 x 28 W, 2 x 55 W) and can be used as simple replacements for these lamps. Constant lumen packages of 2500 lm per module and a system efficiency of 85 lm/W provide the basis for precise planning for a long and efficient luminaire life.

The options for designing new lighting solutions are impressive. The LED modules can be used individuals or they can be arranged seamlessly next to one another. This means that strips of light with a continuous and uniform light emitting surface can be created.
