Kitchen and Bath Professionals Award 6″ to 4″ Retrofit Conversion Kits

Recognized for Innovation in Kitchen & Bath Business Product Awards

An exploded view of a 6" to 4" round conversion kit being installed into a white ceiling near a wood wall.

Recognized for fulfilling market needs through technological advancement, function, aesthetic merit and innovation, DMF’s 6″ to 4″ Round & Square Conversion Kits have been recognized by kitchen and bath designers, architects, custom builders and remodelers in the 2025 Kitchen & Bath Business Product Awards.

 

“Having lighting retrofit options is fantastic – and a square option? I’ve never seen that before,” said Meredith Weiss, founder and president of Merri Interior in Commack, New York, who was a judge in the awards program.

The conversation kits are an ideal architectural retrofit/remodeling solution to easily change a 6-inch downlight to a 4-inch round or square fixture, resulting in a more architectural look.

Square and round retrofit conversion kits

A sustainable and versatile solution, the conversion kits reuse existing housings – no need to rip out the ceiling to change the downlight housing – as drivers are integrated into the LED light engine modules, allowing below ceiling access for easy serviceability, as well as modification with numerous trim styles and optical choices.

 

The high-quality, architectural-grade, deep die-cast aluminum trim styles include Standard, Hyperbolic, Pinhole, Wall Wash, and Flangeless choices that are meticulously designed for unmatched performance for excellent visual comfort. The modules are available in Downlight and Adjustable (360-degree rotation and 45-degree tilt) and the tool-less field-interchangeable optics include 15-, 25-, 40-, 60- and 90-degrees, and Linear Spread and Soft Focus distributions.

 

View the conversion kits, as well as all of the winning products, featured in the September/October issue of Kitchen & Bath Business magazine.

DMF Brings Modular Engineering to Linear Lighting with Premier 0.5 Linear

Featured on Just One Product with Inside Lighting at LEDucation 2026

DMF's .5" Concealed Linear Product Feature in Just One

DMF Lighting’s Samantha Orzel, senior director of commercial growth, recently joined Inside Lighting founder Al Uszynski for a Just One Product conversation at LEDucation 2026, exploring how the company is extending its modular engineering leadership into the linear luminaire category with the Premier 0.5 Linear. The discussion highlights a thoughtfully integrated approach to lighting, where the concealed linear solution is precisely color-matched to DMF Lighting’s downlight and cylinder families, enabling a unified, layered lighting solution across an entire project.

 

Meticulously engineered to deliver seamless, continuous, dot-free architectural illumination, the Premier 0.5 Linear achieves over 400 lumens per foot with impressive efficacy, while embodying DMF’s signature modular philosophy. Balancing high performance with practical innovation, the system features a solder-free, modular design that streamlines installation and provides tool-free field adjustments, while enabling straightforward, long-term serviceability.

 

Specifier demand has consistently revealed a critical gap within the linear category —solutions tend to favor either design flexibility or performance, but seldom both. The Premier 0.5 Linear eliminates this trade-off, uniting architectural-grade output with modular adaptability and precise color consistency across all lighting layers. The result is a cohesive, high-performance system that supports a fully realized design vision.

 

Engineered within an ultra-compact ½-inch profile, the Premier 0.5 Linear delivers continuous illumination without compromise. With broad dimming compatibility, efficacy exceeding 100 lumens per watt, 2000K to 3500K color options, and a high 93 CRI, it ensures both energy performance and visual quality.

 

A universal wiring design further enhances flexibility, allowing wire entry from the side, end, or back of the fixture. Serviceability is equally advanced, enabling component-level maintenance rather than replacing entire runs.

TM-30

See the TM-30 Reports for our products below

What is TM-30?

 

TM-30, developed in 2015 by the Illumination Engineering Society (IES), is an advanced method for measuring the color rendering capabilities of light sources. It addresses the limitations of the older Color Rendering Index (CRI) by providing a more comprehensive and accurate evaluation of how well a light source renders colors.

 

TM-30 is particularly beneficial in environments where precise color rendering is essential. It allows designers and lighting professionals to make more informed decisions, ensuring that the chosen lighting enhances the desired colors and ambiance of the space.
