Lighting control is beautifully simple. Touch the colour pad for red or blue light, the white pad for white light. On the dual colour versions, hold your finger on the pad for more than two seconds and the lamp will cycle through four dimming levels. Release your finger on the light level required. Dual colour EuroLED® Touch lamps can also be remotely operated from multiple points with off the shelf ON/OFF/ON momentary switches. Holding one of the external switches for two seconds will synchronise the lamps to the same dimming level. Light levels are remembered by the lamps circuitry, even when a vessels batteries are turned off. The lamp will always turn on at the colour intensity previously set, regardless of power interruption.
