LightPitch at LEDucation – True 1

Discover DMF Lighting’s True 1 in a LightPitch interview from LEDucation

DMF unveils True 1 at LEDucation 2026

True 1 Takes the Spotlight on LightPitch™

At LEDucation 2026, innovation in architectural lighting was on full display and few products captured attention quite like DMF Lighting’s True 1. In a recent LightPitch™ interview, Samantha Orzel, senior director of commercial growth at DMF Lighting, spoke with Randy Reid, editor of the EdisonReport, to discuss the thinking behind this remarkably compact yet powerful modular downlighting system.

True 1 represents a meaningful evolution in 1-inch aperture lighting. Delivering more than 1000 lumens, it challenges long-standing assumptions about what such a small form factor can achieve. Historically, fixtures of this size have required the compromise of either sacrificing light output or introducing uncomfortable glare. True 1 resolves this tension through a sophisticated three-stage optical stack system that balances performance with visual comfort, resulting in a refined and highly controlled lighting experience.

Editor’s Note (July 2026): At the time of LEDucation 2026, True 1 was referenced as delivering more than 1,000 lumens. Prior to shipment, DMF completed a lens refinement to improve color consistency across viewing angles, a deliberate design decision that resulted in updated output figures. Current production models deliver up to 849 lumens depending on optic configuration. Please refer to the current product page and specification sheet for the latest performance data.

Versatility is equally central to its design. Offered in both fixed and adjustable (360-degree rotation and 35-degree tilt) configurations, the system adapts seamlessly to a wide range of architectural applications. A selection of beam spreads (30-, 40-, and 50-degrees) and color temperatures ranging from 2400K to 4000K, including Warm Dim, allows designers to tailor the lighting environment for specific applications. A high 93 CRI ensures rich and accurate color rendering.

Beyond performance, True 1 reflects DMF Lighting’s commitment to modular engineering. Its cartridge-based design enables field-interchangeable optics and correlated color temperature (CCT), giving specifiers and installers greater flexibility both during installation and over the life of the project. Maintenance is equally considered, with a serviceable DC-to-DC driver accessible from below the ceiling, streamlining upkeep without disruption.

The industry has taken note. True 1 was recognized among the Top 10 MUST SEE Products by EdisonReport at LEDucation, further underscoring its impact and relevance.

For a deeper look into the inspiration and engineering behind True 1, watch the full LightPitch™ interview, which offers valuable insight into how DMF Lighting continues to push the boundaries of what’s possible in architectural illumination.

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.

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.
