Frequently Asked Questions
Is the lamp the same for 230V and 240V? Part number 64781 is available in both voltages. Please check the voltage indicated on your light fixture and select the appropriate version.
Can it be dimmed with a conventional dimmer? Yes, it is fully dimmable ; when dimmed, the light becomes warmer (amber shift).
Safety requirements? Operate only in suitable luminaires with safety screens/glass that contain fragments and filter UV, according to the manufacturer's recommendations.
Installation and safety recommendations
- Check RX7s compatibility, power (2 kW) and voltage (230/240 V) of the luminaire.
- Do not touch the quartz bulb with your hands; use clean gloves.
- Respect the p15 combustion position and the thermal distances of the light manufacturer.
- Use enclosed luminaires and indicate high temperature; the housing must prevent the escape of fragments and UV radiation.
