This fixture uses the Bridgelux Vero 29 COB and the standard driver is 0-10V DC dimmable.
The Retro-fit is for "old work" and is intended to adapt to an existing open frame. Reflector clips can be provided for installation with either a vertical collar or horizontal pan, depending on the existing frame. It is important to have a proper fit between the existing frame and the Retro-fit kit and care should be given in the selection of the proper size.
