OFR-OFI
According to your project and space, you can choose between:
UGR
Unified Glare Rating
This is an approximate model expressing the risk of glare.
The standard values range from UGR 16 (low risk of glare) to UGR 28.
In the standard for workplace lighting EN12464-1, limit values for UGR are imposed for various rooms.
Typical UGR values :
- Office/Classrooms/Meeting rooms : UGR<19
- Corridors : UGR<28
- Staircases : UGR<25
- Warehouses : UGR<25
Quality criteria for drivers
The driver is one of the most critical components in LED solutions. The quality of LED luminaires not only depends on the LED light source and optical design, but also on the efficiency and reliability of the driver. A good LED driver must meet seven quality requirements:
- Lifetime.
- Efficiency.
- Power factor.
- Electromagnetic compatibility (EMC).
- Switching current (Inrush current).
- Waveform current.
- Mains voltage filtering.
Drivers are therefore crucial components in all LED solutions. High-quality drivers can be recognised by requesting the technical fact sheets from the manufacturer to check if the above quality requirements are met. ETAP always provides quality LED drivers, perfectly adapted to the solution and thoroughly tested in our labs.
Lamp colour
3000 K = warm white
4000 K = natural white
5000 K = cool white
Ceiling modulation
ETAP's recessed luminaires are suited for lay-in mounting in ceiling systems with T-profiles.
Other ceiling systems are possible too! Contact ETAP for a customized solution for your ceiling system.
| Modulation | B x L |
|---|---|
| M600 | 600 x 600 |
| M300 | 300 x 1200 |
| M625 square | 625 x 625 |
| M625 linear | 312 x 1250 |
| Bandraster | 300 x various sizes |
Efficacy: lm/W
The specific luminous flux reflects the relationship between luminous flux and power consumption. Just as with fluorescents, a distinction must be made between the light source’s specific luminous flux (LED component, measured at 25° or 85°C junction
temperature and with a standard control current) and that of a luminaire, including driver and optics.
U7
Advanced lighting technology encapsulated in a unique design. The sublime combination of midpower LEDs and sophisticated lenses (LED+LENSTM) ensures maximum visual comfort and optimum light distribution.
Depending on your space or project, choose between:
- The OFR (Optimised For Renovation) version with medium-angle light distribution is optimised for small to medium interdistances (up to 2.4 m).
- The OFI (Optimised For Interdistances) version - with wide or very wide-angle light distribution - was designed to achieve maximum interdistances.
The U7 is also available as a wallwasher, to illuminate boards or walls. With its flexible optical system, the U7 is also ideally suited for refurbishment solutions.
