In short
An LED lighting retrofit keeps the existing luminaire body and replaces the internal parts, swapping the old ballast and lamps for a new LED engine and high-efficiency driver.
A lighting retrofit upgrades a fitting from the inside. Instead of removing luminaires and buying new ones, the existing body stays and only the internals change.
What gets replaced
- Lamps and lamp holders
- Ballasts, replaced with high-efficiency LED drivers
- Optional new diffusers
- Optional sensors for presence or daylight control
What stays
The luminaire body, mounting and position, so ceilings and installation details stay as they are.
Why retrofit
- Lower upfront cost than full replacement
- Lower energy and running costs
- Less waste and embodied carbon
- Ideal for protected ceilings and listed interiors
How reLUMEN8 does it
299 Lighting's reLUMEN8 service collects, refurbishes and tests fittings off site, then returns them ready to install with a renewed 5-year warranty.

Is retrofitting cheaper than replacing lights?
Retrofit usually reduces upfront cost because the luminaire bodies are reused rather than replaced.
