1. Introduction
DARAY’s X740 is a state-of-the art, cost-effective examination light for use during
medical or veterinary consultation and diagnosis. The light uses the latest LED
technology to give an intense light at the ideal colour temperature for accurate
medical diagnosis (without the need for secondary filtering) with virtually no heat.
Multiple mounting options are available.
The X740 features a high-output intensity and variable colour temperature, which is
variable via a touch panel on the side of the light head. The light operates from a
safe low voltage produced by a mains transformer, and has a swivelling, spring-
balanced arm system and a rotating head to allow accurate and stable positioning of
the light-patch.
The light comprises 3 parts: light-head and articulated arm system, power-supply
module, and the mount of choice. The rigid spring-balanced arm allows the light-
patch to be placed accurately and stably where it is needed.
All versions are delivered in special-to-type packaging which identifies on the ends of
the box the model type and serial number of the light within.
This user & installation guide contains all the information you need for installation,
operation and maintenance.
