LED - Surgical 4” Downlight Luminaire

MSD-4

The MSD-4 Surgical Downlight is a precision-engineered solution designed to deliver superior illumination in surgical environments. As a leading surgical downlight, it provides supplemental lighting for general procedures and primary illumination for minimally invasive surgeries. Its advanced optical design minimizes glare on monitors and reflective surfaces, ensuring visual comfort for surgical teams. Built with a gasketed flush lensed assembly, this luminaire creates a sealed barrier that prevents contaminated air from entering the surgical field, supporting stringent infection control standards.

Engineered for demanding healthcare settings, the MSD-4 combines durability, performance, and compliance. The fixture features a factory-sealed COB LED light engine, delivering up to 5000 lumens with exceptional color consistency and CRI options up to 95 for accurate tissue rendering. Available in multiple color temperatures from 2700K to 5000K, it meets diverse surgical suite requirements. The luminaire’s gasketed flush lensed design ensures easy wipe-down and maintains IP65 protection on the room side, while optional regressed lens configurations provide IP64 compliance. These features make it ideal for medical lighting applications where hygiene and reliability are paramount.

Beyond illumination quality, the MSD-4 offers robust electrical and mechanical performance. Its programmable, dimmable driver supports smooth 0–10V dimming down to 1%, giving surgical staff precise control over light levels. Certified to MIL-STD-461G for EMI/RFI emissions, the fixture safeguards sensitive medical equipment from interference. The antimicrobial powder-coated trim finish enhances infection control, while compatibility with grid, drywall, and surgical ceilings ensures installation flexibility. ISO-3 cleanroom rating and NSF2 Splash Zone certification further reinforce its suitability for critical environments. With a lifetime exceeding 60,000 hours (L70) and a five-year warranty, the MSD-4 delivers long-term value and peace of mind.

In surgical suites where precision and cleanliness are non-negotiable, the MSD-4 stands out as a trusted solution. Its combination of high lumen output, advanced sealing technology, and compliance with rigorous standards makes it an indispensable component of modern surgical suite lighting strategies. Whether for new installations or upgrades, this luminaire ensures optimal performance and reliability in every procedure.
