The essential advantages of compact fluorescent lamps are their long service life and the reduced energy consumption, especially when using electronic control gear. Their compact dimensions and energy efficiency makes them ideal for use in downlights. In their basic form, downlights direct light downwards in narrow or wide beams.

and can especially be used to produce ambient lighting. The higher a room is and the larger the ceiling, the more anyone looking up is likely to be dazzled by light from the luminaires. Downlights installed in particularly glare-sensitive areas - for example, over conference tables - should be fitted with reflectors which provide exceptional glare control. The Lightcast downlights have cast aluminium housings which are designed to provide optimum thermal properties according to their respective technical requirements. Other typical Lightcast features are the cast aluminium mounting ring and the four-point mounting which allows luminaires to be installed without tools. The Darklight technology combines the maximum visual comfort with the maximum light output ratio.
The DALI compatible luminaires feature digitally addressable control gear, which can individually address every single luminaire, i.e. using the ERCO DALI Light System and the pre-programmed ERCO Light Studio software.
