Lighting controller
DMX
DMX (Digital Multiplex) is a digital control protocol that has prevailed especially in event technology for lighting control. With this control signal, you can control many different functions that are on channels, e.g., the brightness of the individual colours. How many luminaires can be controlled with the DMX controller depends on the individual luminaires, which require more or fewer control circuits depending on the type. This kind of control comes into its own particularly in the combination of HESS and LEC.

CLO - Constant Lumen Management
The luminous flux of all lamps, including LEDs, reduces as they age. The extent to which this declines depends on various parameters. Nowadays, however, this decline can be counteracted using an electronic control system, ensuring that a consistent luminous flux is maintained throughout the lamp’s lifetime, whilst also saving energy.
Without constant luminous flux
Without CLO
Over the course of an illuminant's life, its luminous flux falls by approximately 10% (L90B10), but the system output remains unchanged. The drop in luminous flux must be taken into account when planning through use of the lamp luminous flux maintenance factor (LLWF). This means that the lighting system must be designed to consume more energy from the outset, in order to compensate for the decline in luminous flux and still provide the required amount of light at the end of its service life.
With constant luminous flux
With CLO
The integrated electronics increase the flux over the illuminant's life and thereby keep the luminous flux constant. This does increase the system output over the illuminant's life, but you save energy right from the start because you don't have to oversize your lighting system.
