ErP Regulatrions are focused on producing energy-efficient lighting solutions. The new Energy-related Products (ErP) Directive 2009/125/EC replaced the old Energy-using Products Directive (EuP) in 2009. The updated ErP Regulation includes products that indirectly affect energy use, such as insulation materials. Besides, to enhance sustainability, the European Commission has introduced updated regulations:
These new directives aim to reduce energy waste, improve product efficiency, and promote environmentally friendly solutions across industries.

The SLR defines the different light sources and control gears covered under the regulation. Under the new regulation, light sources are classified as anything that emits white light, including LED lamps and LED modules. Luminaires are also identified as containing products for light sources.
What are control gears? They are enhancements that stabilise the current and control the lighting output of a light. They also reduce any lighting flickers and promote stable energy consumption.
Energy Labels are found on all electrical energy-using products, including televisions, dishwashers, and light sources. Their purpose is to communicate energy efficiency, which allows users to save money on their household energy bills and make choices to help reduce CO2 emissions.
The new Energy Label Regulation redefines the labelling requirements for all lighting products, including labels for lighting packaging and any website or sales literature.

From Sept. 1, 2021, the declared power consumption of a light source PonP_{on}Pon shall not exceed the maximum allowed power PonmaxP_{onmax}Ponmax (in W), defined as a function of the declared useful luminous flux ΦusePhi_{use}Φuse (in lm) and the declared color rendering index CRI (-).

The standby power PsbP_{sb}Psb of a light source shall not exceed 0.5 W.
The networked standby power PnetP_{net}Pnet of a connected light source shall not exceed 0.5 W.
Threshold efficacy (η in lm/W) and end loss factor (L in W) are constants used for computations and do not reflect the true parameters of light sources. They depend on the light source type in Table 1.
Correction factor (C) depends on light source, and additions to C for special light source features are specified in Table 2.
Efficacy factor (F) is:
(R) > CRI factor (R) is:

How is the ERP Regulation LED Strip different from standard LED strips?
ERP Regulation LED strips are designed following the European Union’s Energy-related Products (ErP) regulations. These strips are more energy efficient than the standard LED strip lights. Moreover these ERP compliant are also more expensive than standard ones.
Are ERP Regulation LED strips dimmable?
ERP Regulation is an energy efficiency standard for lights. It doesn’t decide whether an LED strip is dimmable or not. If the ERP Regulation LED Strip is designed for dimming and is connected to a compatible dimmable power supply or controller, you can surely dim it.
Is the ERP Regulation LED Strip suitable for commercial and industrial use?
In commercial and industrial applications lights are turned on for long hours, sometimes all day long. So using ERP Regulation LED Strip in this case plays a crucial role in minimizing power consumption as they are highly energy efficient. moreover, these strips also save you electricity bills.
Can I replace my existing LED strips with ERP-compliant ones?
Yes, you can replace existing LED strips with new ErP-compliant ones. However, make sure the new LED strip is compatible with the existing driver and doesn’t cause voltage drop issues.
How can you understand your light’s energy level?
First of all, you have to understand the below concepts:
1. Non-directional mains light source (NDLS, MLS)
2. Non-directional non-mains light source (NDLS, NMLS)
3. Directional mains light source (DLS, MLS)
4. Directional non-mains light source (DLS, NMLS)
To make it simple, MLS means directly goes for 230V electricity, and NMLS needs a transformer to transform to 230V.
(DLS) means a light source having at least 80 % of total luminous flux within a solid angle of π sr(corresponding to a cone with an angle of 120%); otherwise, it’s NDLS.
So, how can we define the DC voltage led strip correct efficiency class level?
No doubt this is NMLS, cos it needs a transformer.
And it’s NDLS because the total luminous flux within a solid angle of π cannot reach 80% luminous flux.
Now you can see it’s NDLS and NMLS, and it’s in the 2nd line. Factor Ftm shall be 0.926.
E.g., if your light output luminous flux is 100lm/W, you need to put an additional coefficient that’s 0.926, 100*0.926=92.6lm/w.
