The term 'TYPE OF LIGHT' can refer to four different types of light: INFRARED (8 letters), NEON (4 letters), Klieg (5 letters), and Strobe (6 letters). INFRARED light is a type of electromagnetic radiation that has a longer wavelength than visible light, and is used in many applications such as night vision and thermal imaging. NEON light is a type of gas discharge lamp that produces a bright orange-red light when an electric current passes through it. Klieg light is a type of bright arc lamp that is used in the film and television industry for lighting large areas. Finally, strobe light is a type of light that produces a series of flashes at regular intervals, and is often used in photography and entertainment.
