Structure and characteristics

They achieve light efficiency
up to 77 lm/W for the luminaire

Lamp diffusser
Frozen made of polymethyl methacrylate (PMMA)

High-performance, constant current
and programmable
Available functions:
- adjustable output current
- programmable time programs
- temperature control on the module
- power regulation of the luminaire with output voltage
- maintain constant light output over time

Overvoltage protection
Increases the immunity of the luminaire to electrical discharges up to 15 pulses at 10 kV

Polypropylene with fiberglass, UV-resistant
