Fonroche treats lighting evidence as a design tool
Our work connects optical measurement, system engineering and field installation so project teams can make defensible choices.

“A photometric file becomes useful only when its distribution is understood in the geometry, environment and operating conditions of a real project.”
Since 1995, Fonroche has developed outdoor lighting capability around the practical questions asked by engineers, contractors and asset owners. A high luminous efficacy value can support energy goals, yet it does not replace attention to uniformity, glare, spectrum, thermal behavior or maintainability. We therefore organize project conversations around evidence: what was measured, what is assumed in the calculation, and what installers must preserve in the field.
Candela distribution, luminous flux and electrical inputs are captured for the relevant configuration so exported files remain traceable to a defined product state.
Ingress protection, temperature behavior and construction details are reviewed alongside optical performance because outdoor reliability depends on their interaction.
Calculation models test mounting and distribution choices before equipment reaches site, making design assumptions visible to all project participants.
Technical notes
Our publication program separates measured properties from application assumptions. Documents explain file formats, optical families, maintenance factors and the tradeoff between maximum lm/W and visual quality.
