Attention! Code no longer in production
Technical description:
Rigid-profile product for linear LED lighting, designed to be surface-mounted. Extruded aluminium bar structure, with diffusing opal polycarbonate linear screen. Moulded polycarbonate sides and end closing caps. Removing the end closing caps allows direct connection to the next profile thanks to a practical quick-coupling system. Version with 18 LED 24Vdc high emission module (total 18W) - white colour, warm white tone (3100K) colour rendering index - CRI 95 (recommended for use in museums). Ballast not included.
Installation:
Profile snap-on fixing on accessory clips (MWJ8); the clips are fixed to the installation surface with screws and screw anchors (not included). 
Other fixing systems are available: 
adjustable arms (MWJ5 - L100; MWJ6 - L200), adjustable base (MWJ4)
Colour:
Aluminium (12)
Mounting:
wall surface|ceiling surface
Wiring:
Constant voltage ballasts to be ordered separately:
electronic 50W 24V (MWK4) - electronic 70W 24V dimmable 1-10V (MWK5).
Power supply end cap with cable (MWJ9 - for connection to the ballast);
intermediate power supply cap with cable (MWK0 - for connection between modules)
Notes:
For fixing, connections and power supply, use the components available with a separate code. For large installations and considerable lengths, DIN rail mounted electronic ballasts can be used:
9910 (72W) - 9911 (96W) - 9912 (240W)
