Philips Gardco Form Ten Round luminaires are a natural complement to their rectilinear counterparts. Architecturally, the series lends itself to an extensive variety of building motifs, permitting the designer to choose to draw attention to the luminaire or to have it gracefully fade into the surroundings. Now, by incorporating state-of-the-art, high performance LEDs, these luminaires provide the classic shapes desired today together with the energy saving advantages of the source for tomorrow. Available in the 17" size, the Form Ten Round LED luminaires are offered in two styles - the domed top "M" series and the cylindrical "C" series. Both models preserve the features and benefits that make them industry leaders in site illumination. A one-piece, die cast aluminum door frame contains a heat and impact resistant glass lens and is fully gasketed with memory-retentive, hollow core silicone rubber. The lens and optical pan hinges down with a quarter turn of a captive stainless steel screw. The driver assembly is prewired with quick disconnects and simply dismounts for service or replacement.
