Thorn OSQ 150 narrow-beam projector floodlight

New-old-stock Thorn OSQ 150 for 1 x 150w G12 metal halide lamp.

A narrow beam high intensity projector with IP54 optical and gear compartments, cast aluminium, black finished body and black cast-aluminium wiring box.
Ideal for highlighting high tower installations, where powerful illumination with excellent colour rendering is required.
Used in isolation, the high intensity narrow beam is ideal for lighting architectural features without wasteful spillage of light on to surrounding details. Variation in beam achieved by a choice of front glass.

The same body is also used for the OQ1000 which uses a 1kW CSI PAR64 lamp.
