Useful light
The distribution supports meeting the required road-lighting class without reproducing gaps or glare from the old system instead of maximising lumens outside the area that matters.

LED street lighting retrofit
An LED street lighting retrofit upgrades an existing road network while working with pole, bracket, cabling and control constraints. Each replacement scenario still needs a photometric check.
- Street lighting retrofit layout based on geometry and the required result, not wattage alone
- Road-specific distribution selected from geometry and the required lighting class
- Explicit assumptions for asset inventory, existing pole geometry, baseline performance and reuse limits
- A direct connection between calculation, suitable product series, evidence and quote

Road and public-space lighting
What the project should achieve
A useful specification balances visual performance, reliability, operating cost and the realities of installation.
Controlled glare
Position, optics and aiming account for users and road users, residents and changed brightness at reused pole positions.
Predictable operation
Controls, environmental conditions and maintenance access are part of selection rather than an afterthought after pricing.
A verifiable specification
The result connects targets, visible assumptions, the proposed variant and evidence the project team can check.

Design criteria
These are the decisions that shape fixture selection, photometric work and the final quote assumptions.
| Design criteria | Design approach |
|---|---|
| Asset inventory | Record poles, spacing, height, bracket, tilt, setback, luminaire, circuit and condition with reliable location data. |
| Target classification | Reconfirm road use and required class rather than treating the legacy installation as the performance brief. |
| Reuse assessment | Check structural condition, mounting interface, cabling, cabinets, controls and surge environment before fixing scope. |
| Scenario comparison | Test one-for-one, bracket changes, selective pole additions and control options against performance and lifecycle constraints. |
| Rollout verification | Use a pilot, installation settings and measurement plan where risk or programme scale justifies field confirmation. |
Design criteria
Selection guide
Use these comparisons to narrow the system direction before choosing an individual model.
- Start with geometry
- Dimensions and mounting positions determine the useful distribution before wattage is considered.
- Use maintained targets
- Design for the required maintained result and declared maintenance assumptions, not initial lumens alone.
- Compare the distribution
- A lower-power fixture with the right optic can be more useful than a higher-output fixture with poor placement.
- Check the environment
- Temperature, dust, moisture, impacts, corrosion and electrical conditions can change the suitable series.
- Keep assumptions visible
- Any missing drawing, target or operating condition should remain explicit until the project team confirms it.

Standards and verification notes
Applicable targets depend on the country, site and project class. Final compliance must be checked against the current project brief and calculation.
