Why dim? IME nearly all commercial & school fluorescent installs are heavily overpowered.

Why? The need to dim lights in a domestic setting easy to understand. But

1. Ignorance. Some installers don't fully know what they're doing.
2. For cleaning some people want extra bright lighting
3. Variations in eyesight & perception cause variations in desired light level.
