About the Strand SL Series
The Strand SL Series encompasses the SL19, SL26, SL36 and SL50, recognised for having the smallest dimensions in their fixture category. Each model features a high-efficiency dichroic glass reflector paired with coated aspheric computer-designed lenses, optimised for 575W GLC lamps with GLA long-life lamps also supported. Coolbeam operation extends gobo, shutter and gel life, while shutters operating in three planes allow triangular shutter cuts. A bayonet lamp-changing system, fast peak and flat field adjustment via screw drive, and 360-degree body rotation make the SL Series straightforward to rig, focus and maintain. The wide gate accepts two gobo holders, a drop-in iris or a rotating gobo holder, and UL and cUL listings confirm compliance for professional installation.
Strand SL Series — buyer FAQs
What are the Strand SL Series fixtures and what beam angles do they cover?
The Strand SL Series is a family of compact, lightweight ellipsoidal profile luminaires comprising the SL19, SL26, SL36 and SL50, covering beam angles of 19°, 26°, 36° and 50°. Each model shares the same lamp house, uses a high-efficiency dichroic glass reflector with coated aspheric computer-designed lenses, and is claimed to have the smallest dimensions in its fixture category.
What lamp does the Strand SL Series use, and what is Coolbeam operation?
SL Series fixtures are optimised for 575W GLC lamps, with GLA long-life lamps also available as an alternative. Coolbeam operation is a thermal management approach that reduces heat at the gate, extending the working life of gobos, shutters and colour gels. Lamp centering uses a positive screwdriver lock to prevent movement in transit, and the bayonet action system allows lamp changes without disturbing the field setting.
What gobo and shutter options does the Strand SL Series support?
The wide gate on each SL Series fixture accepts two gobo holders simultaneously, including a glass gobo holder, a drop-in iris or a rotating gobo holder. Shutters operate in three planes, enabling triangular shutter cuts. Body rotation of 360° combined with two yoke balance positions makes gobo and shutter positioning straightforward during rigging.
Who makes the Strand SL Series and where does it sit in the brand's history?
Strand SL Series fixtures are made by Strand Lighting, a theatre and television lighting brand with roots going back to 1914 in London. Strand built a reputation across stage and studio fixtures, dimming systems and control consoles. Through successive ownership changes the brand eventually became part of Philips and its entertainment lines have since been consolidated under the Vari-Lite name, making used SL Series units a legacy fixture from that lineage.
What should I check when buying a used Strand SL Series fixture?
Check which beam angle variant is being sold (SL19, SL26, SL36 or SL50) and confirm the lamp type fitted. Inspect the dichroic reflector and aspheric lenses for coating damage, examine the shutter blades and gobo holders for heat wear, and verify that the bayonet lamp-change mechanism and peak/flat screw-drive adjustment operate correctly. Each listing on this page shows condition details; purchases carry a 21-day warranty covering major functional faults, with full detail in the buying guide at 10kused.com/used-av-equipment-guide/.
