Process guides.

These guides explain how a LED retrofit and sustainable lighting project runs from first call to completed installation: surveys, sample assessment, specification, programme, off-site work, installation and testing. Use them to plan budgets and programmes, or to explain the process to building owners and tenants.

What these guides cover

• What happens at each stage
• What information to prepare
• Typical programmes and disruption

All process guides

• How the reLUMEN8 retrofit process works — reLUMEN8 works in four steps: schedule a call, assess a sample fitting with a site survey, refurbish and test fittings off site, then deliver them ready to install with a renewed 5-year warranty.
• What warranty do retrofitted fittings have? — Luminaires retrofitted through reLUMEN8 come with a renewed 5-year warranty after refurbishment and testing at 299 Lighting's facility.
• Why a lighting survey comes before a retrofit — A lighting survey records existing fittings, condition, quantities and light levels so a retrofit can be scoped, priced and prioritised accurately.
• Retrofitting lighting in occupied buildings — Off-site refurbishment keeps disruption low in occupied buildings, with fittings swapped in phases so spaces stay in use.
• What to send for a retrofit quote — For a fast retrofit quote, send photos of the fittings, approximate quantities, building location, ceiling type and any goals such as adding controls.
