Quadra recessed spotlights are a system of compact recessed spotlights with square or rectangular aperture. A feature of this system is that the inserts of the 1x, 2x or 4x lamp luminaire units can be tilted up to 40° off the vertical. They can also be rotated horizontally through 360°. This allows a beam to be aimed at almost any area of the room, to provide the intended lighting effect. Typical areas of application are showrooms, sales areas, museums and galleries.

The lamps used in the single, double and four-lamp units in size-4 are low-voltage halogen reflector lamps. The special Softec lens allows the QR-CBC lamps in Quadra recessed spotlights to produce museum quality lighting. The one- or two-lamp Quadra recessed spotlights of size 7 are available in versions for up to 100W low-voltage lamps, QPAR30 halogen reflector lamps and for HIT-CE highintensity discharge lamps. Quadra recessed spotlights are ideal to combine with the Quadra recessed ceiling luminaire product range. The separately packaged invertible mounting frame allows every Quadra luminaire to be mounted either with an overlapping trim or to be flush mounted in plaster ceilings.
