How to specify the right Road Lamp

Frequently asked questions about the ER-312 Road Lamp

What colour temperature should I specify?

4000 K neutral white is the safe general choice for industrial and commercial interiors. 3000 K suits hospitality and retail where a warmer look is wanted. 5000-6500 K is common for outdoor and roadway lighting.

What IP rating do I need for outdoor use?

IP65 is the practical minimum for exposed outdoor fixtures. For wash-down or coastal locations, specify IP66 with a corrosion-resistant housing and confirm the IK impact rating.

Can the fixtures be dimmed or sensor-controlled?

Dimming and sensor variants depend on the driver fitted to the model. Tell us the control protocol you use (0-10 V, DALI, triac) and we will confirm compatible models.

Do you supply photometric data for lighting design?

IES/LDT photometric files can be supplied for project models so your designer can run the lighting calculation in DIALux or Relux.
