Lighting retrofit / Introduction

Survey and payback

A redesign, not just a lamp swap

A retrofit is not a lamp swap, it's a redesign. The light levels of the old system are no longer where the standard or the work requires them to be.

The survey starts by measuring the current state: how much light there is where, how much energy is consumed, and what condition the luminaires are in. This shows where replacing the light source is enough, and where a new luminaire or a new layout is needed.

The payback calculation looks at more than the electricity bill: luminaire lifetime, lumen depreciation and maintenance costs all count. Sometimes the more expensive luminaire pays for itself sooner.

What you get

Four documents for your decision

Measurement, recommendation and calculation: backed by numbers, not left to estimates.

Payback calculation

Consumption, lifetime and maintenance together, broken down by year.

Replacement plan

Which luminaires stay, which are replaced, and with what.

Installation schedule

Phasing, so work can continue while operations keep running.

Condition assessment

Measurement of existing light levels, energy consumption and luminaire condition.

Who it's for

Where a retrofit delivers the most

Large floor area, long operating hours, old luminaires: these three together are the best combination.

Public institutions

Standards-compliant lighting for schools, public offices and sports facilities.

Offices and retail

Workplace light levels and UGR, complemented by occupancy sensing.

Industrial plants and halls

High ceilings and continuous operation, where energy consumption shows up fast.
