New LED Medical Exam Light Uses 50 Percent Less Energy and Increases Visibility
The DRE Vista LED diagnostic light is compact, maneuverable, and gives a large flood pattern. It is available in a variety of configurations: Dual Ceiling mount, Single Wall mount, Single Ceiling mount, and a Portable system.
The Vista LED exam light features a 28” (71 cm) articulating arm with integral compression spring and a 23” (58 cm) Extension Arm. The arm rotates 40 degrees up and down from horizontal plane, and the lamphead and arm both rotate 540 degrees. The light includes 5-Stage Dimming and On/Off Switch and can be controlled from the Sterilizable Handle.
LED lights are a green, environmentally friendly option that consume about 50 percent less energy than similar halogen lighting, and last many times longer. LED lights have a life span of 50,000 hours, compared to halogen lights (which last between 1000 and 2000 hours) and gas discharge bulbs (which can last about 5000 hours).
The light emitted from an LED light is whiter than that of a halogen bulb. Halogen lighting is naturally yellow and will require numerous coatings and filters to achieve a similar effect.
The greatest source of heat in the operating room has typically been the beam of the surgical light, but LED lights virtually eliminate this problem. The heat comes from IR light, which can’t be seen by humans. LEDs can be designed to emit only light in the visible spectrum.
LED lights also give a large flood pattern with improved shadow control. A halogen system typically consists of a single bulb and a multifaceted reflector, and each facet is a different shape and distance from the bulb. This creates hot and cold spots within the light pattern. LED lights are designed to precisely overlap, so no matter how many LEDs you block, the spot remains round and consistent. This consistency means surgeons are not distracted by shadows moving across the pattern.
