Solo CSI Followspot

Followspot - 2000W (Halogen) or 1000W (CSI/CID)
Solo 2k: 2000W (GY15, CP79 Halogen) Followspot. 9/15 degrees.
As Cadenza 9/15 but with integral 24-leaf iris diaphragm and horizontal strip shutters rotatable through 50 degrees, and side and rear handles. Balance-adjustable fork with TV spigot mount.
Colour magazine is optional accessory, sights are included with the lantern.

Solo CSI/CID: 1000W CSI or CID (G22 EHT) discharge lamp followspot. Internal EHT, external regulation unit, otherwise as Solo 2K.
Ballast has a three position rotary switch enabling the lamp to be switched to standby (25% power), half-power and full.

Introduced as replacements to the Patt 818 and 765 followspots in 1985. They have many advanced features and considerable light output benefit. The housings appear similar in shape but the CSI has a power bulge at the rear to accommodate the high voltage starting gear for the discharge lamp, and obviously a separate control ballast.
Solo 2K has a variable beam from 9° to 15° compared with the 818 12° to 21°. Therefore, in making light output comparisons, it is very easy to have a much higher intensity on the new unit at 9° when compared with the larger spot of the 818.
Discontinued in 1997
