One of the great features of the Strand SPX Ellipsoidal series is the interchangeability of fixed beam and zoom lens tubes to the body of the fixture as needed for specific venues and changing productions. This 19° Fixed Beam Lens Tube for SPX Ellipsoidal by Philips Selecon allows the SPX to project beam diameters of 8.4 - 23.4' at throw distances of 25 - 70'. The medium narrow beam is perfect for projecting gobo patterns at a distance or for use with an iris for even narrower beams or special effects. This is an ideal lens to take advantage of the SPX's peak/flat light distribution control.
