Scolmore Deco Resistive/Inductive Dimmer Switch is developed largely for use with Tungsten, Halogen and Low Voltage lamps. The dimmer switch is interchangeable with the dimmer modules used in the MiniGrid range. Recommend the use of branded halogen lamps with all Deco dimmers. The use of inferior, non-branded lamps may require the nominal rating of the dimmer to be reduced. This Resistive/Inductive Dimmer Switch have not been designed for use with LED lamps. However, this may be suitable for some good quality LED lamps.
