Producent Relco Concept The light dimmer in 100W for LED and incandescent bulbs. If you need a foot dimmer for LED or an incandescent bulb, this model is a great choice. The dimmer has a soft start/stop function (which doesn’t blind), and it is programmed with a memory function unless the power cuts out. The dimmer automatically finds out whether the lamp uses LED or an incandescent bulb. The maximum wattage is 4-100W for LED and 25-160W for incandescent bulbs.
