LED Drivers & Power Supplies

Choosing the right LED driver starts with load. Add up the total wattage of the fittings on the circuit, then size the driver with headroom rather than running it at its limit, since a driver working well within its rating runs cooler and lasts longer. Constant current drivers suit fittings rated at a fixed current, such as downlights and modules, while a constant voltage led power supply suits strip and other fittings designed for a fixed voltage. Dimming protocol must match the control system on site, whether that is leading-edge, trailing-edge, DALI or 0-10V, and mixing them is one of the most common causes of flicker and callbacks. Confirm dimming compatibility between driver and fitting before ordering. For projects using strip, the LED Strip Lighting range covers the strips and accessories these drivers are built to power.

A commercial lighting spec is only as reliable as the power behind it, so the LED driver should be specified alongside the fittings rather than added as an afterthought. Selecting each LED driver power supply against its fitting keeps compatibility issues out of the commissioning stage and reduces callbacks after handover. Where a project calls for recessed lighting, the Downlights range gives specifiers fittings to pair with a matched driver, while the Commercial range covers the wider fit-out, from battens and panels to DALI control. Specifying fittings, drivers and controls from one supplier means one point of contact for compatibility questions and one order to track. Sizing drivers with headroom at this stage also makes late layout changes easier to absorb. Trade pricing and stock availability across the full range are confirmed through the Domus Partner network, so quantities and lead times are settled before work begins.
