Re: CBUS and CFL's

[Lehane Kellett <lehane@xxxxxxxxxxxxxxxxxxx>]

Having just been through a build I can confirm that dimmable
'domestic'
luminaires are in very
short supply and mostly the design is cr*p. In the end to meet the
requirements we used
CFL uplighters from Tornado and normal 12v halogen downlighters. All
dimmed with DMX
(0-10V for the CFL, having swapped the ballast for Osram Quicktronic).

To each of the CFL's we wired a switched 230V feed and a 4 core 300v
rated control cable
back to the Node.
