Three things that shape a room's light
Before comparing fixtures, it helps to separate three ideas that are often confused: the lamp technology, the colour of the light it produces, and where that light lands in the room.
Lamp technology
LED, halogen, compact fluorescent and incandescent lamps differ in efficiency, lifespan and the way they render colour. Most new installations in Canada now use LED.
Colour temperature
Measured in kelvin, this is the warmth or coolness of the light. A warm 2700K lamp suits a bedroom; a cooler 4000K reads as crisper in a workspace.
Lighting layers
Ambient, task and accent light each do a different job. Combining them lets a single room shift from morning routine to a quiet evening.
