Typical applications
- Commercial interiors: offices, retail, showrooms and hospitality
- Industrial high-bay lighting for warehouses and workshops
- Outdoor area, street and roadway lighting
- Warehouse, logistics and cold-store facilities
- Project lighting specified through M&E contractors
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 3U 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.
