Lightcast Recessed luminaires for high-pressure discharge lamps

ERCO Lightcast Recessed luminaires Introduction

The Lightcast recessed luminaires for general lighting have cast aluminium housings. The Darklight technology combines the maximum visual comfort with the maximum light output ratio. This results in the darklight reflector having consistent cut-off angles for a variety of lamps and aperture sizes. Within the cut-off angle there is no disturbing glare.

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.

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.
