What LED lamp to use with a lighting control system?

Leading edge or trailing edge

The lamp has to suit the way the control system dims: leading edge (also called forward phase) or trailing edge (reverse phase).

Some control systems are phase adaptive: they adjust themselves to leading or trailing edge lamps. Some lamps are dual-compatible and work with either.

Before you choose lamps

• Match the dimming type

  Use lamps made for your system’s dimming type, or dual-compatible lamps.

• One lamp per circuit

  Don’t mix lamps on a circuit, such as GU10s with LED strip, or two models of GU10. It can cause dimming problems even when every lamp is the same dimming type.

• Test before installing

  Try your chosen lamps on the system first, so you can satisfy yourself of the dimming.
