Trion. Lighting effects for ceilings

The ceiling washlight for sophisticated lighting that makes ceilings appear higher


Excellent uniformity

ERCO has developed luminaires designed to achieve particularly uniform illuminances to meet the stringent requirements of ceiling washlighting.


Coloured light

Coloured light can be used to design and change the surroundings by adding subtle or dramatic contrasts. LEDs provide you with a highly efficient and flexible tool to create coloured light.


Wide or deep beam

The Spherolit lenses with wide or deep beam permit adjustment of the light distribution to suit the relevant lighting task.
