The lights output is controlled locally at a wall mounted
knob (Figure 2). Dimmer knobs are also mounted
directly to the fixture.
Since these lights will need to be replaced in the near
future an analysis of what type of fixture will replace
the existing one was conducted. The two analyzed
were LED OR lights and an in kind replacement of the
existing halogen fixtures.
Halogen lights have a number of problems with them:
beam temperature, immediate failure, additional energy
costs, and inability to adjust color. The beam
temperature is critical as radiation is reduced, thus the
surgeons are more comfortable, and the patient’s
exposed tissue will not dry out as quickly, allowing
longer surgeries. Halogen bulbs fail instantaneously,
while LEDs dim out, so a catastrophic failure will not

occur and replacement can be scheduled. With beam Figure 5: OR Surgical Light Control Panel
temperature adjustment LEDs can change their color,
thus allowing ideal contrast for each procedure. This may allow superior outcomes for the patient.
RESULTS
There is a definitive direct saving in installing LED Lights into the operating rooms. Tables 2A & 2B summarizes these
savings. An interesting note is that for the LED fixtures it doesn’t matter if it s a large or small luminaire, either way the
consumption is 144W per fixture. This was pulled directly from Skytron’s product catalog (Appendix III), which is a
likely manufacturer for this replacement.
