BASF Unveils High-Efficiency, Low-Carbon Yellow Light Solutions for Specialized Industrial Applications

Ludwigshafen, Germany – May 12, 2026 – BASF has announced a next-generation yellow light material solution designed for industries handling photolithography-based manufacturing processes, including semiconductors, printed circuit boards (PCBs), display manufacturing, LED production, and photovoltaics. This breakthrough technology is intended to completely replace traditional yellow fluorescent lamps and filtered LEDs while maintaining the strict spectral control required for yellow light processes. This innovation enhances energy efficiency, reduces power consumption, and lowers carbon footprints, helping customers achieve sustainability goals without compromising performance.

Traditional yellow fluorescent lamps block short wavelengths below 530nm to protect sensitive processes, but this filtering wastes energy. BASF's new solution employs an absorption-conversion mechanism that not only blocks harmful wavelengths (cutting wavelengths below 530nm for high-end semiconductor applications) but also converts them into useful yellow light, maximizing energy utilization and system performance.

The technology can be seamlessly integrated into existing lighting fixtures, such as fluorescent tubes, panels, and explosion-proof designs, while ensuring spectral purity, uniform brightness, and visual comfort. It is also compatible with existing power and thermal systems, simplifying installation and reducing deployment risks.

Key benefits compared to conventional yellow fluorescent lamps and LED yellow light tubes include:
- Reduced power consumption while maintaining equivalent brightness, cutting electricity and cooling costs.
- Energy-saving effect: Switching from traditional fluorescent or filtered LEDs to BASF's solution reduces energy usage by 25%.
- Reduced heat transfer, improved stability, and longer service life.
- Compliance with RoHS and REACH regulations regarding restricted substances.
- Excellent thermal stability and long-term reliability; performance has been proven under high-temperature processing conditions, with zero measurable degradation even after more than five years of use in actual semiconductor manufacturing environments.

Typical applications include cleanroom lighting, lithography, PCB inspection, and other processes requiring strict short-wavelength control. BASF and its partners provide technical support, including sampling, on-site evaluation, and carbon footprint analysis, to accelerate the implementation of high-efficiency, low-carbon lighting environments.

Calculation Methodology:
Operating time: 24 hours/day × 365 days = 8,760 hours/year; Electricity rate: $0.30/kWh (IEA industry average); CO2 emission factor: 0.5 kg CO2/kWh (2023 IEA world average); CO2 absorbed by one tree: approx. 22 kg/year.

| Lighting Type | Power consumption per tube | Annual energy consumption (1,000 tubes) | Annual CO2 emissions |
| :--- | :--- | :--- | :--- |
| Traditional Fluorescent Lamp | 36 W | 315,360 kWh | 157.7 tons |
| Filtered Yellow LED | 20 W | 175,200 kWh | 87.6 tons |
| BASF Light-Conversion LED | 10 W - 15 W | 87,600 kWh – 131,400 kWh | 43.8 tons – 65.7 tons |
