SAS740 Lights

Linear Ceiling Lights | SAS740 | Lighting Options

Overview

SAS740 is the most versatile of SAS’ integrated linear ceilings, able to accommodate complex geometry and void access. Unlike other continuous linear profile systems, SAS740 can intersperse with acoustic infill panels. 

Now incorporating lighting, the aluminium system is suitable for spaces requiring a premium aesthetic alternative to suspended ceilings.

System features

Access

Void access can be achieved through demounting profiles.


Profile Sizes

SAS740 is currently available in 50 mm x 200 mm x 3000 mm profile sizes.

Luminaire unit sizes:

  • 1200 mm
  • 1500 mm
  • 1800 mm
  • 2400 mm
  • 3000 mm

For sufficient quantity we will consider bespoke dimensions.


Finishes

SAS740 is available in all standard SAS finishes. Bespoke finishes are available on request, including polished and anodised.


Applications

SAS740 lights add an integrated general illumination capability to an SAS740 installation. Lit sections can be mounted individually or in a continuous fashion, with control gear mounted in the top of the profile (not visible from below.) SAS740 lights are designed to deliver well balanced lit environments suitable for large spaces and central circulation areas.

The profile has space to allow up-lighting to be included with allowance for gaps at support brackets and driver locations.


Lifetime and maintenance

The LED light source used in the SAS740 will still deliver over 90% of their peak light output after 60,000 hours of operation. Electronic control gear will operate for 100,000 hrs with a maximum 10% failure level.

Light modules can be accessed for maintenance from below by removing the diffuser, and easily demounted by releasing the retaining spring clips positioned in each corner.

Control gear may be replaced by unplugging the remote pack.


Emergency

Emergency lighting is provided through 3-hour maintained emergency versions of the light module. All emergency lighting provision calculations should be approved by a suitably qualified person.

Emergency gear must be mounted within 1m of the luminaire separately on the support grid rather than within the profile.


Control system compatibility

Each individual unit is supplied with a DALI addressable and dimmable control gear. Modules with integrated emergency provision have an additional DALI addressable and reporting emergency converter.


Optic

Opal polycarbonate diffuser or glare control lens options available.
