Why is the incandescent light bulb important?
- They are cheap to manufacture
- Low voltage lamps can have relatively compact filaments which allow good capture and control of the light
- They are wide bandwidth sources which can permit good colour matching
- They require no complex and heavy control gear
- They emit limited amounts of UV light, and therefore lamp houses do not generate ozone
