Disclaimer:

The light temperature colour guide provided on this website is for informational and educational purposes only and is designed to offer general guidance for understanding colour temperature, Kelvin ratings, and lighting applications using standard industry information and common lighting practices. While this tool provides systematic approaches to colour temperature selection and includes current standards from major lighting manufacturers, the guidance provided is for educational purposes and may not substitute for professional lighting design advice or manufacturer-specific recommendations for your particular application.

Key Points to Consider:

General Guidance: The colour temperature information provides general guidance based on industry standards and common practices, but may not address unique lighting requirements, specific fixture compatibility, or specialised applications.
Professional Design Required: Complex lighting installations should be performed by qualified electricians or lighting professionals following manufacturer instructions and local electrical codes. Incorrect installation can result in electrical hazards, fixture damage, or safety risks.
Variable Real-World Factors: Actual lighting requirements may vary due to factors not covered in the guide, such as room size, ceiling height, natural light availability, colour rendering requirements, dimming compatibility, and individual visual preferences.
Not Professional Advice: This tool does not constitute professional lighting design advice, electrical installation guidance, or suitability verification for specific applications. For commercial installations, accessibility compliance, or safety-critical lighting, consult qualified lighting professionals.
Colour Perception Accuracy: Individual colour perception varies, and actual appearance of light temperatures may differ from digital representations due to screen calibration, viewing conditions, and personal visual sensitivity differences.
Manufacturer Variations: While based on industry standards, different LED manufacturers may have slight colour temperature variations, CRI differences, or specific requirements not reflected in this general guide.
Tool Reliability: No warranty is provided regarding the accuracy, completeness, or continued functionality of this colour temperature guide. The information, recommendations, and technical guidance are provided "as is" without guarantee.
No Liability: The authors and affiliates accept no responsibility for any injury, damage, incorrect purchases, installation issues, or other consequences arising from the use of this guide or following its recommendations.

By using this tool, you acknowledge that you understand its limitations, accept that no guarantee of lighting suitability is provided, understand when professional advice is required, and agree to this disclaimer.
