The dichroic filter is on the inside surface of the bulb lens. Reflector surfaces have a bright aluminum coating. The filter produces a specific color by selectively transmitting only the desired wavelengths of light, with virtually no heat absorption. Light of the other wavelengths is reflected back into the lamp.
