How to Achieve UGR<19 in Commercial LED Lighting Design: Optical Solutions for Retail & Hospitality Projects
Discover how ELYCEN lighting achieves UGR<19 glare control through advanced optical design, deep reflectors, and COB LED solutions for commercial lighting projects.
How to Achieve UGR<19 in Commercial LED Lighting Design?
Introduction
In commercial lighting projects, brightness is not the only factor that determines lighting quality.
For retail stores, hotels, offices, and showrooms, excessive glare can create visual discomfort and reduce the overall customer experience.
Therefore, professional lighting designers increasingly require UGR<19 LED lighting solutions to achieve comfortable and premium environments.
At ELYCEN, we combine light body constructure engineering, optics design, COB LED technology, and thermal management to develop commercial lighting products with excellent glare control.
1. What Is UGR and Why Does It Matter?
UGR (Unified Glare Rating) measures the discomfort caused by excessive brightness from lighting sources.
A lower UGR value means better visual comfort.
UGR Level | Application |
|---|---|
<16 | Precision environments |
<19 | Offices, premium retail, hospitality |
19-22 | General commercial spaces |
>25 | High glare environments |
For European commercial projects, UGR<19 has become an important lighting quality requirement, especially for:
- Fashion stores
- Luxury retail shops
- Hotels
- Restaurants
- Office spaces
2. Why Traditional LED Lighting Creates Glare Problems?
Many standard LED fixtures have several issues:
① Direct LED Exposure
LED chips are highly concentrated light sources.
Without proper optical control:
- Strong brightness contrast
- Eye discomfort
- Uncomfortable customer experience
② Shallow Reflector Design
A shallow reflector cannot effectively control the light angle.
Result:
- Light spills into unwanted directions
- Increased glare
③ Incorrect Beam Angle Selection
Different applications require different beam angles.
Example:
Application | Recommended Beam Angle |
|---|---|
Jewelry display | 15°-24° |
Fashion retail | 24°-36° |
General store | 36°-60° |
