When buyers talk about high efficiency LED track lights for retail, they usually hear one thing: "high efficiency." But very few manufacturers can prove it.
At YNDLUX, we back our claims with data. Our AC track lighting series achieves 165 lm/W real luminous efficacy — verified in IES photometric files that we provide to every project buyer, free of charge.
What Does 165 lm/W Actually Mean for High Efficiency LED Track Lights?
Luminous efficacy (lm/W) measures how much light output you get per watt of electricity consumed. The higher the number, the more energy-efficient the fixture.
Most standard LED track lights on the market deliver 110 lm/W at CRI80 — and drop to just 80 lm/W at CRI90, because higher colour rendering requires more energy. Premium European brands reach 130–140 lm/W at CRI80, but still fall behind at CRI90.
YNDLUX high efficiency LED track lights achieve 165 lm/W at CRI Ra≥90 — more than twice the efficiency of typical Ra90 fixtures. That means:
- A 20W YNDLUX track light delivers the same lumen output as a conventional 35–40W fixture
- Energy savings of 40–50% versus standard-efficiency alternatives
- Lower heat output, longer lamp life, reduced maintenance costs
For retail chains operating hundreds of fixtures per store, this difference is significant on the electricity bill — and even more significant on the carbon footprint report.
Ra ≥ 90: Colour Rendering That Sells Products
In retail, light doesn't just illuminate — it sells. Poor colour rendering makes clothing look dull, food look unappetising, and jewellery lose its brilliance.
Our track lights are rated at CRI Ra ≥ 90 as standard, with Ra ≥ 95 available for specialised applications such as:
- Fashion retail — accurate fabric and colour representation
- Jewellery and accessories — gemstone brilliance and metal lustre
- Food and supermarket — fresh produce and deli counter appeal
- Art and museum — faithful reproduction of colours and materials
The difference between Ra 80 and Ra 90+ is immediately visible to the human eye — and directly impacts customer purchasing decisions.
IES & LDT Files: The Professional Standard You Should Demand
Photometric data files — IES (.ies) from the Illuminating Engineering Society and LDT (.ldt / EULUMDAT) widely used across Europe — contain the precise light distribution data for a fixture: beam angle, intensity, lumen output at every angle, and more. Lighting designers use IES and LDT files in software such as DIALux or Relux to simulate exactly how a space will look before installation. European projects typically require LDT format, while IES is the standard in North America and Asia.
YNDLUX provides IES and LDT (EULUMDAT) photometric files for every track light model. This matters for several reasons:
- Design accuracy — Your lighting designer can simulate the exact result before you order, using IES or LDT files in DIALux/Relux
- Compliance — IES/LDT data supports EN 12464-1 calculations for retail illuminance requirements
- Transparency — Real measured data from EVERFINE goniophotometer, not marketing claims
- Project approval — Many European retail chains require LDT/IES file submission for fixture approval
If a supplier cannot provide IES or LDT files, treat their lm/W claims with caution.
EVERFINE Laboratory Equipment: How We Test and Verify 165 lm/W
Claims are easy. Proof is what matters. At YNDLUX, every luminous efficacy figure is measured in our in-house testing laboratory using EVERFINE professional photometric equipment — the same brand trusted by TÜV, SGS, and major European certification bodies.
Integrating Sphere Optical Test Centre
Our EVERFINE integrating sphere system is primarily used to verify colour temperature (CCT) accuracy and colour rendering performance (CRI/Ra) for every LED fixture. It measures spectral power distribution, chromaticity coordinates, and colour consistency across production batches — ensuring that every unit matches the specified 3000K, 4000K, or custom CCT within tight SDCM tolerances. This is the internationally recognised method per CIE 84 and IEC 62722-1 standards. When we state Ra≥90 with precise colour temperature, this is the equipment that proves it.
IES Dark Room Testing Centre
Our EVERFINE goniophotometer in a certified dark room is the core instrument for measuring luminous efficacy (lm/W) and beam angle distribution. It captures light intensity data at every angle around the fixture, generating professional photometric files in both IES (.ies) and LDT (EULUMDAT .ldt) formats. European lighting designers predominantly use LDT files in DIALux and Relux software to simulate real-world installations — LDT is the standard photometric format across Europe per EN 13032-1. The dark room environment eliminates stray light interference, ensuring measurement accuracy per IES LM-79 standards.
Having both systems in-house means we can test every production batch — not just prototypes — giving buyers confidence that the IES/LDT photometric files and lm/W specifications match the actual delivered products. We provide both IES and LDT file formats for all models — just specify your preferred format when requesting project data.
