Method

## What every guide compares

Each guide works through the same five checks, so results stay comparable across models and brands.

- **Optics** — Beam angle, distribution curve and glare behaviour against the original fixture.
- **Installation** — Mounting interface, bracket and recess dimensions, surface compatibility.
- **Power** — Driver range, voltage, wattage and dimming behaviour per configuration.
- **Control** — DMX, DALI and 0-10V coverage, including channel mapping for addressable versions.
- **Certification** — CE, IP rating and test documents for the target market and application.
