Cylinder Surface-mounted luminaires
The housing of the Cylinder surface-mounted downlights for general and accent lighting and for wallwashing is made of powder-coated, corrosion-resistant aluminium. The Darklight technology combines the maximum visual comfort with the maximum light output ratio. The high protection mode surface-mounted downlights are suitable particularly for the transitional areas between indoors and outdoors. Cylinder surface-mounted downlights illuminate entrance zones, arcades or atriums effectively. In indoor areas where protection against moisture or dust is required, they ensure high-quality lighting even in these harsh environmental conditions.

Diffuser technology
The diffuser technology of Lightcast optimises visual comfort. The diffuser effectively increases the size of the light source thereby reducing the luminance in the light aperture. The small hole in the centre of the diffuser simplifies lamp replacement. Depending on the lamp, either translucent plastic diffusers or frosted glass diffusers are used.

Directional luminaires
DownlightsThe downlights produce a wide-beam light distribution for ambient lighting, e.g. for entrances or passages.
Lens wallwashersThe lens wallwasher produces an asymmetrical light distribution for uniform illumination of vertical surfaces.
Directional luminaires
The narrow beam angle of the directional luminaires is ideal both for highlighting architectural details and accenting objects. The lampholder carrier can be tilted by up to 20°.
Darklight technology
ERCO downlight reflectors are calculated using complex computer programs. This results in the reflectors having consistent cut-off angles for a variety of lamps and aperture sizes. Within the cut-off angle there will be no disturbing glare. This is the characteristic feature of the ERCO Darklight technology. The Darklight technology combines maximum visual comfort with maximum light output ratio and an exceptional balance between horizontal and vertical illuminance.
The standard cut-off angle of the ERCO downlight range is 40°; this is the angle between the horizontal ceiling surface and the diagonal from lamp to reflector edge. The standard range is complemented by downlights with 30° and 50° cut-off angles.
