# Solid State Lighting Services, Inc. (SSLS)

> SSLS is a specialty consultancy in the science and application of light, with deep expertise in LED and solid-state lighting technology. Founded by scientists Morgan and Lisa Pattison, SSLS has advised the U.S. Department of Energy (DOE) Lighting R&D Program for over 20 years and authored the national Solid-State Lighting R&D roadmaps.

## What SSLS does

SSLS helps manufacturers, growers, researchers, environmentalists, legal teams, and buyers understand, develop, and apply lighting — from the physics of the semiconductor light emitter to how light interacts in real-world settings (greenhouse, residence, eco-resort, wildlife habitat, roadway, or display).

## Expertise areas

- Underlying Technologies & Materials: LED devices and materials, micro-LEDs, UV emitters, laser diodes, micro-cavity LEDs, quantum dots, OLEDs, displays, and opto-electronic materials — grounded in device physics and materials science.
- LED & Lighting Technology: independent technology assessment, reliability, testing, and product evaluation across LED, laser, conventional, and alternative light sources.
- R&D Strategy & Management: technology roadmapping, funding strategy, and proposal writing and review, including the U.S. DOE Solid-State Lighting R&D roadmaps.
- Product Development: spectral engineering, form-factor design, and lighting R&D from concept to working prototype; advanced chandeliers, historical lighting preservation and re-creation, and architectural-character lighting.
- Horticultural Lighting: grow-light spectra, product selection, and controlled-environment agriculture R&D.
- Light Pollution & the Nighttime Environment: night lighting audits, sky-radiance / light pollution measurements, and responsible outdoor lighting for parks, protected areas, eco-resorts, and cruise ships.
- Light & Health: circadian and non-visual effects of light, photobiomodulation (red light therapy), therapeutic lighting, and germicidal UV.
- Light & Animals: spectra engineered for the biology of wildlife, livestock, and aquatic species.
- Expert Witness: testimony on lighting and display technology, product claims, intellectual property, and light pollution.

## Representative engagements

- Product Development: specialized LED materials, devices, and lighting products — commercial linear lamps, UV-A curing lights, UV-B lights, runway guidance lights, photobiomodulation (PBM) lights, and advanced horticultural lighting.
- Lighting Reliability: evaluation and analysis of LED and lighting product failures, including phosphor blue-shift of roadway fixtures; characterization and documentation of product failures, and warranty support.
- Lighting Forensics: teardown, reverse engineering, measurement, and characterization of lighting products and the lighting conditions of indoor and outdoor settings. Measurements include intensity, spectral power distribution, illuminance, irradiance, spectral reflectance, color filters, luminescent materials and films, electrical inputs, circuit configuration, and optical distribution — in-situ or in the lab.
- Night Lighting Audits (National Park Service): night lighting audits and light pollution measurements across national parks, seashores, and urban environments; ranger training; best practices for lighting in parks and protected areas.
- Horticultural Lighting R&D: head of horticultural lighting R&D for Luxx Lighting; grow-light spectral optimization and controlled grow studies; helped a very-large-scale greenhouse select and purchase high-quality lights.
- Eel-Diversion / Wildlife Protection: lighting layouts to guide migratory eels away from hydropower infrastructure hazards.
- Solid-State Lighting R&D Roadmaps (U.S. DOE): technical advisors to and authors of successive annual editions of the national lighting R&D Roadmap and R&D Opportunities reports.
