CARSON, Calif., July 15, 2026 – DMF Lighting, a leading architectural lighting manufacturer of premium modular LED downlighting systems, has introduced its new 8″ to 4″ Retrofit Conversion Kit, making it easy to upgrade outdated recessed lighting without disturbing existing ceilings and reusing existing wiring. Designed to retrofit standard 6-inch through 8-inch round housings to modern 4-inch architectural downlights, the new kit expands upon DMF’s previous 6-inch conversion kits offering by accommodating larger housings and supporting high-lumen adjustable LED modules.
Engineered for renovation and modernization projects, the conversion kit is available for both insulated ceiling (IC) and non-IC applications and is compatible with industry-standard recessed housings with a minimum volume of 50 cubic inches. The kit pairs seamlessly with DMF’s M Series modular light engine modules and trim families and the H Series 4-inch flanged modules and trims, allowing existing installations to be transformed into sleek 4-inch flanged or flangeless architectural downlights while preserving finished ceilings. An installation collar provides a secure, flush fit.
“Many renovation projects require balancing performance upgrades with minimizing disruption to the existing space,” said Ken Czech, vice president of new product development at DMF Lighting. “This conversion kit allows installers to modernize larger legacy housings with our modular 4-inch platform while gaining the long-term benefits of below-ceiling serviceability, quick-change components and enhanced dimming performance.”
The modular design simplifies both installation and future maintenance. Embedded drivers housed within the LED light engine modules eliminate the need to access the ceiling plenum for servicing, while quick-connect electrical connections allow modules to be replaced from below the ceiling. The tool-less below-ceiling servicing is enabled by two driver options based on lumen output: an embedded module driver for standard lumen packages and a touch-safe detachable driver for higher-lumen non-IC applications. DMF adapter options enable reuse of the existing housing wiring.
The embedded driver architecture also delivers smooth, flicker-free dimming to 1% and below is compatible with most 0-10 volt or TRIAC/ELV dimming controls.
The retrofit light engine modules are available in Downlight and Adjustable (360-degree rotation and 45-degree tilt). Tool-less, field-changeable optics enable beam distribution to be tailored on-site, with options including 15-, 25-, 40-, 60- and 90-degree beam spreads, as well as Linear Spread and Soft Focus distributions.
Multiple lumen packages are offered up to 1500 lumens for IC applications and 3500 for non-IC applications. Color temperatures include a choice of 2400K, 2700K, 3000K, 3500K, 4000K and Warm Dim (3000K–1800K), all delivering a 93 CRI. Color consistency is maintained within a 2-step MacAdam ellipse to provide uniform illumination across an installation.
Complementing the modular system is a broad selection of precision-engineered deep die-cast aluminum trims, including Standard, Hyperbolic, Pinhole, Wall Wash/Sloped Ceiling, Decorative and Flangeless styles. Each trim is wet-painted to create a durable matte finish and is available in White, Black, Bronze, Clear Diffused or custom RAL colors.
To introduce the new retrofit solution, DMF Lighting will host a webinar on Tuesday, July 21, 2026, at 10:30 a.m. PT. The session will provide an overview of the conversion product and demonstrate how it simplifies lighting upgrades by transforming existing recessed housings into high-performance 4-inch LED downlights. Attendees will also learn about housing compatibility, installation best practices and key application benefits. The webinar is complimentary and registration is now open: https://dmflighting.zoom.us/webinar/register/6017835298871/WN_NJaoX372Q8Gq90uR-UkIuw#/registration.
Designed with sustainability and long-term performance in mind, the system is ENERGY STAR® certified, Declare Listed and meets California Title 24 JA8 requirements while complying with RoHS standards. Fixtures are also wet location rated, NSF Listed and DarkSky Approved to help reduce glare and minimize light trespass.
