1. GENERAL DESCRIPTION
DARAY’s Bilite is the world-renowned dental operating light which employs twin-beam
technology to eliminate shadows in the oral cavity. The light produces a wide, virtually
cold, rectangular light patch with extremely sharp edges.
The light head is mounted on DARAY’s sophisticated balanced suspension arm which is light
to move and does not drift once positioned. The Bilite features variable-intensity control on
the wall and ceiling-mounted models, and all versions operate from a safe, low voltage fed
through the suspension arm to the light head.
DARAY’s extremely quick and simple lamp-bar change is retained, allowing blown bulbs to
be swapped quickly without risk of burnt fingers.
The ceiling or wall light comprises 4 parts: a mounting, a variable-intensity power-supply
module, a suspension arm, and the light head. The power-supply module is fitted with an
IEC inlet so the mains may be supplied via a plug-in flex from a standard mains socket. This
arrangement can readily be converted using a parts kit supplied as standard for use where
the mains-electrical supply cables are ‘chased’ into a wall. The power-supply module is
fastened to the wall-mount bracket for the BLLW and can be screwed to the wall to power
the BLLC.
The unit-mounted BLL comes with the light head, suspension arm and separate transformer
for mounting with the chair-package utilities.
