WHAT IS ERP ENERGY EFFICIENCY LEVEL OF DOWNLIGHT?
In the realm of LED downlight energy efficiency, products are classified according to their luminous efficacy, measured in lumens per watt (lm/W). The scale ranges from A (highest efficiency) to G (lowest efficiency), with an A-classified downlight achieving a luminous efficacy of 210 lm/W or more, and a G-classified light falling below 85 lm/W.
Note: It is important to note that many products in the market showcase energy efficiency ratings based on the performance of the COB (Chip on Board) LED module alone, not taking into account the complete downlight system.
Frequently Asked Questions
What is the energy efficiency classification for these downlights?
Energy efficiency is measured in lumens per watt (lm/W) on a scale from A to G. Class A represents the highest efficiency (≥210 lm/W), while Class G is for products below 85 lm/W.
What is the Color Rendering Index (CRI) of this model?
This product features a high CRI of ≥90ra, ensuring vivid and accurate color representation for indoor environments.
What type of LED technology is used?
It utilizes COB (Chip on Board) LED technology, which provides a high-density light output and excellent thermal performance.
What is the expected lifespan of this light?
The product is designed for long-term durability with a working time rating of ≥30,000 hours.
Is the system efficiency different from the COB module efficiency?
Yes, it is important to distinguish between the efficacy of the LED chip alone and the complete downlight system, as the full system includes driver and optical losses.
What does the IP20 rating indicate?
An IP20 rating indicates that the fixture is protected against solid objects larger than 12.5mm but is not water-resistant, making it suitable for indoor use in dry areas.
