KSR Lighting is widely respected by electrical contractors for its versatile, installer-friendly commercial and domestic downlight ranges. Their catalog emphasizes CCT (Color Changing Technology) and multi-wattage toggles that reduce the amount of stock an electrician needs to carry on their van.
The key downlight products driving their lineup include:
FireBreak QR Select Series (Domestic Flagship)
The FireBreak QR is KSR’s premier fire-rated architectural residential downlight range, heavily praised for its quick-install properties and versatility.
-
FireBreak QR Select: Features an all-in-one 12-in-1 or 8-in-1 configuration. It incorporates a Quad CCT switch (allowing toggling between 2700K, 3000K, 4000K, and 6000K) and dual-wattage selection (5W or 7W) directly on the back of the luminaire. It comes with push-fit / quick-fit plug-and-socket terminal blocks and is IP65 rated, making it ideal for bathrooms.
-
QR Pro Baffle Select: Offers the same switchable technology but features a recessed anti-glare baffle design for high-end residential or hospitality spaces.
-
FireBreak QR WiZ GU10: A smart-lighting version integrating WiZ technology, allowing RGBW and CCT control straight from a smartphone without needing a central hub.
QR Pro Modular Range (Customizable)
Designed for flexible specification, the QR Pro series features an LED Modular build. Electricians can select a base engine (can-be insulation coverable) and pair it with a vast range of secondary architectural trims:
-
Fixed, tilt, or wall-wash configurations.
-
Interchangeable round or square bezels.
-
Baffle options finished in White, Black, Chrome, Matt Gold, or Rose Gold.
Sorocco Select Series (Commercial Downlights)
For commercial applications like offices, retail spaces, and corridors, the Sorocco range provides high-lumen, broad-coverage lighting.
-
Sorocco Multi-Wattage CCT: Features a 100° wide beam angle, switchable multi-wattages (e.g., 6W/8W, 10W/15W, or 18W/26W variants), and triple CCT switching (3000K/4000K/6000K). It is IP44 rated from the front and comes backed by a 5-year commercial warranty, with optional integrated self-testing emergency modules.
Mimas Mini Series (Accent Downlights)
-
A range of micro 3W LED downlights designed for niche accent lighting, display cabinets, or minimal aesthetic architectural lighting. Available in fixed, tilt, or low-glare baffle options.
