Specialty lighting is lighting where the control method is part of the specification rather than a detail. When the output has to follow a schedule or a biological rhythm, the driver, the protocol and the curve fidelity decide whether the installation works at all.
1. What is in this section
- Tunable White DALI-2 HCL
From colour temperature to circadian stimulus, melanopic EDI, and DALI-2 control architecture.
2. Where to start
Start from the requirement rather than from a product. Each page here opens with the condition that makes the problem what it is — the crop and the dose, the cleanroom class, or the schedule the output has to follow — and only then moves to parameters and selection. Read the first section before comparing products; it usually rules out more than a datasheet would.

4. What these pages do and do not settle
They settle the reasoning and the method, so that a figure taken from them can be checked against the page that carries it. They do not commit to a part number or close a design: the range changes with availability, and the current figures sit on the product pages. For a specific parameter, go to the specification pages; for a background argument, these are the pages to read in full.
