Darkroom safelights provide working light in a darkroom so clinicians or technicians can see while developing x-ray films. These lights are designed to provide light in wavelengths that will not expose the x-ray film or impact the development process. Any dental practice using film x-rays should have a darkroom space, and a safelight is a key part of a functional darkroom. Some dental darkroom safelights feature swivel mounts to allow the light to be precisely positioned for each use of the darkroom. Another feature available on darkroom safelights is a sensor that can automatically turn the light on when the regular lights are turned off within the darkroom. If your practice is using film x-rays, having a darkroom with a safelight is a necessity.
