What LIGHTGLASS does

LIGHTGLASS is a Philadelphia-based designer and manufacturer of architectural simulated windows and skylights, founded in 2019. The company's core product uses edge-lit tunable-white LED light engines (CCT 2200K-6500K, dimming to 0.1%) housed in extruded-aluminum frames with tempered glass or polycarbonate lenses, engineered to occupy only 3.75 inches of wall or ceiling depth. The products ship as prefabricated Standalone units or clustered Arrays, available in any dimension in 1-inch increments up to 24 square feet per unit at flat square-foot pricing. The company sells through a North American rep agency network ("Find A Rep"), targeting architects, designers, general contractors, and building owners who specify products in construction documents; products are classified under AIA MasterSpec Division 085693, "Special Function Windows, Simulated Windows & Skylights."

The product portfolio includes core Simulated Windows & Skylights, the Wallglass wall-mount variant, Skyglass for ceiling/grid applications, and the SunDial control system that automatically tunes color temperature and intensity to match the sun at the user's timezone without requiring third-party control systems. Three specialty configurations extend the addressable market into regulated clinical environments: an Anti-Ligature configuration officially approved by the New York State Office of Mental Health (per 2025 OMH Guidelines) using 1/4-inch impact-resistant polycarbonate and tamper-resistant hardware; a Non-Ferrous MRI-safe configuration with remote drivers and per-unit magnet validation; and the MasterSpec Division 8 inclusion that legally defines the product as an architectural opening rather than a light fixture.

Revenue is generated entirely through hardware product sales via the rep channel, with healthcare as the primary vertical (over 100 healthcare systems illuminated in North America, including Mayo Clinic, Cedars Sinai, Mount Sinai, Children's Hospital of Philadelphia, Nemours, and multiple VA facilities), and secondary exposure to commercial offices, residential (including a Puerto Rico historic property and NYC townhome), and institutional segments (Red Bank High School, an automobile museum). The company holds Red List Approved, WELL v2, LEED v4, UL DAMP/DRY/Anti-Ligature/Non-Ferrous, and Buy American Act / Build America Buy America certifications, and has received Architectural Record's Architectural Lighting Product of the Year (2021) and Architectural SSL's Product Innovation Award (2021).

Core offering

LIGHTGLASS designs and manufactures prefabricated simulated windows and skylights that recreate the visual and circadian qualities of natural daylight in windowless interior spaces. Products use edge-lit, tunable-white LED light engines integrated into extruded aluminum and tempered-glass frames, available in Standalone and Array configurations with custom sizing at no incremental cost. The company sells primarily to architects and project specifiers via a rep agency network, with specialty healthcare configurations for behavioral-health (anti-ligature) and MRI (non-ferrous) environments.

Product overview

LIGHTGLASS offers a portfolio of simulated window and skylight products that bring the experience of daylight into windowless spaces. The core offering consists of LIGHTGLASS Simulated Windows & Skylights, available in two primary configurations: Standalone (individual prefabricated units) and Array (multiple units clustered together). Product variants include Wallglass (wall application) and Skyglass (ceiling application), with specialty configurations for healthcare settings including Anti-Ligature (behavioral health) and Non-Ferrous (MRI environments). Add-on control systems include SunDial for automatic circadian rhythm regulation. All products feature tunable-white/dimmable LED light engines in extruded aluminum frames with tempered glass or polycarbonate lenses, supporting 2200K-6500K CCT range with dimming to 0.1%.

Products and services

• LIGHTGLASS Simulated Windows & Skylights Architectural prefabricated simulated windows and skylights that recreate the light quality and spatial experience of an actual window using edge-lit tunable-white LED light engines in extruded-aluminum and tempered-glass frames. Sold as Standalone units or clustered Arrays with custom sizing up to 24 square feet at standard square-foot pricing.
• Wallglass Wall-mounted version of the simulated window, comprising two layers of tempered glass edge-lit by full-spectrum, tunable-white/dimmable LED light engines in an extruded-aluminum frame. Less than 4 inches deep, WELL v2-compliant, available in seven sizes ranging from 13 to 42 inches square and 25 by 49 inches.
• Skyglass Ceiling/skylight configuration of the simulated window product line, using 18 inch by 42 inch units with a shroud that drops into 2x4 grid ceilings to provide functional task lighting in addition to vertical-plane circadian stimulus.
• SunDial Control System Automatic circadian-rhythm control system that mimics the color and brightness of the sun in the user's local timezone, enabling tailored circadian lighting interventions without third-party control systems.

Quantifiable outcome

• 68.4% of participants in dim-white light condition met criteria for clinically significant depression compared to 42.1% in bright-white light condition (NIH research cited by LIGHTGLASS)
• +2 more outcomes
