Description
SCRIPT LIGHTS
These units, constructed from elegant aluminium extrusions, have fully adjustable shutters to provide a narrow 'curtain' of light directed at the work surface. They have integral electronic ballast, and have Northlight (near illuminant D65) tubes with a colour temperature of approximately 6500 K. The cases are available in three sizes, to take 600mm (18 watt), 900mm (30 watt), and 1200mm (36 watt) tubes, and are finished black eggshell stove enamel. Spare lamps are also available. 220/240 volt operation.
50Hz units are available dimmable in two different versions, low voltage dimming and DALI/DSI & switchDIM.
The low voltage control dimmable script lights require a special dimmer controller, available as a separate item. This has a variable dimming rotary control and a push on-off facility. The dimmer is suitable for use with single-gang flushmount backbox (minimum depth 40mm). A surface mounting dimmer unit is available to special order.
An alternative version of the dimmable script lights can be controlled either digitally by DALI/DSI control or by switchDIM. DALI/DSI allows the script light to be individually addressed and operated by commercial lighting control software (not supplied), allowing predefined levels, timed control etc. Operation via switchDIM requires the direct connection of a suitably rated push to make switch for dimming and switching. A brief push (<0.6s) will switch the ballast ON and OFF, when pushed continually the ballast will either dim or brighten. At switch ON the ballast will return to the previous level prior to switch OFF. More than one script light can be controlled simultaneously and can be synchronised to 50% by a single 10s push of the switch. Note that push switches with indicator lamps cannot be used.
