How the calculator works
The calculator uses the site area type, current fitting load, typical operating pattern, expected LED load, energy rate and project cost to estimate annual saving and simple payback.
A default UK electricity carbon factor is kept in the background so the user gets a carbon signal without having to manage reporting assumptions inside the tool.
Why industrial projects need extra context
Industrial spaces often have higher switching cycles, harsher environments, access constraints and more disruption risk when fittings fail. That means durability, ingress protection, impact protection and maintenance intervals can be just as important as headline efficacy.
The same wattage reduction can produce very different real-world value depending on access equipment, downtime cost and operating pattern.
What to review after the estimate
When the saving looks viable, luminaire range checks cover mounting height, ambient conditions, switching frequency and emergency integration. Robust battens, linear industrial luminaires, panels for support spaces and emergency options all need the correct project context.
