## Buyer Intent Signals
Problems: Standard Lighting Defaults: Using standard office lighting or generic industrial lighting without adherence to specific photobiological or colorimetric standards. | Internal Standardization Manuals: Internal teams attempting to define their own metrics for color reproduction or light safety without external benchmarks.
Solutions: international lighting standards body | who created CIELAB color space | photobiological safety of lamps standards | definition of a standard observer in colorimetry | how to measure office lighting for health compliance | General Safety Standards: Adhering to general safety standards like UL or CE which may mention light but lack the depth of CIE colorimetric systems.
