The LEDlux Tread steplight is 240 volts, warm white and IP54 rated. It is not dimmable and should not be used with a circuit which has an existing dimmer on it. Whilst only using a mere 2 watts, the Tread produces the perfect light output for an entry way, a guiding light through a corridor. Suitable for coastal locations and with an IP54 rating and peace of mind of our 3 year warranty.
