Car park lighting in Treflys
What we do in Treflys: new columns, LED lantern upgrades and controls for car parks. For Treflys retail and business parks, part-night dimming keeps the car park safe while cutting overnight energy use.

Local car park lighting in Treflys
Many car parks around Treflys still use sodium lanterns on columns that are structurally fine. Swapping just the heads for LED gives whiter, more even light for much less power.
Older columns in Treflys sometimes show corrosion at the base. We check condition before fitting new lanterns.
For Treflys premises we plan works around opening hours, deliveries and shared access, which matters on mixed-use estates and high streets.
