Luminaire or lamp has a built-in motion detector. The light will switch on when a movement is detected.
Luminaire or lamp has a twilight switch function. This automatically switches on the lights as it gets dark.
Colour temperature is expressed in kelvin (K). The higher the colour temperature, the cooler the impression of the light:
2700K: extra warm white 3000K: warm white 3500K: neutral white 4000K: cool white 5000-5500K: daylight 6000K: cool daylight
Extra warm white creates a warm, inviting atmosphere (e.g. hotel, living room, and catering). Warm white can be used for a pleasant atmosphere (e.g. retail and office). Neutral cool white creates a more businesslike atmosphere, this color gives a sterile atmosphere. Low lighting levels are obtained in interior with warm white light. If a very high level of light is needed, neutral or cool white light is a good choice.
Dim to warm is a dimming technique that adjusts colour temperature as the light is dimmed: it shifts from warm white to extra warm white when fully dimmed. This technique has various names, such as Dimtone or Glowdim.
