How to specify the right Energy-saving Lamp

Work from the required lux level at the task plane, then the mounting height
Match beam angle to the space: narrow for high ceilings, wide for low uniform coverage
Check the IP and IK rating for the installation environment
Confirm colour temperature and CRI with the interior designer or specifier

Frequently asked questions about the 4U Energy-saving 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.
