The water coolable LED-LE lighting system from DH Licht cannot be surpassed due to its modular structure in terms of flexibility and application. Whether in production or research, in climate chambers, in greenhouses or multi-layer culture systems. The LED-LE can be individually adapted to your needs and always offers optimal light conditions. The luminaire can be equipped with LED circuit boards on one or both sides.

Up to a power of 200 watts, the LED-LE is passively cooled by air. Active water cooling is used for a higher power. This means that the system can be operated with up to 800 watts and generate a photon flux of over 2000 μmol/s. In addition, the LED-LE can be mounted both horizontally and vertically.

The control of the LED-LE via DALI protocol can be integrated directly into a climate computer or via our VisuSpectrum 2.0 software.

Our contribution to sustainability:

With the LED-LE it is possible to exchange all components and thus the luminaire is particularly sustainable, since only a one-time purchase of the housing is necessary. A repair or an update can be carried out at any time.
