Lighting can make us

look better.

feel better.

be better.

I help you create healthy lighting products.


What is healthy lighting?

Modern lighting has a dark side. When designed inappropriately, LED systems can emit too much glare, flicker unacceptably, cause accidents, and even disrupt the body's cycle of wake and rest.

Healthy lighting is different.

It takes inspiration from the fundamental qualities of natural light.

It supports optimal human health and safety. 

It makes people look and feel great in any environment, at any time of day. 

My story.

My first word was light. Really.

From age six, I built an animated holiday light show that won the city contest so many times, it was disqualified.

At university, I discovered a lab studying the links between light and health. I designed luminaires and controls for research on individuals with dementia and mental disability.

I then started one of the first circadian lighting controls companies, which was acquired.

I led human-centric lighting strategy and product development at a major lighting components company, launching multiple successful product lines.

Now I work with companies to make healthy lighting a reality.


Differentiated and profitable.

A healthy lighting product doesn't have to be a rocket ship, requiring years of R&D and millions in investment. There are already products like this, and they are not selling.

Everyone loves nice-to-haves, but these are what cause scope creep, delays, and cost overruns.

When we work together, we drill down to the essence of the market requirements. We consider everything that makes it into the product and everything that does not.

The process.

Your brand, customer base, and products are unique. When we work together, we step back to first principles and question all assumptions in order to achieve excellent product-market fit.

1. Discovery

Using interviews and survey data, I gain a deep understanding of customer and business priorities.

2. Strategy

I work with stakeholders to prioritize features as we create flexible and exciting roadmaps that will keep customers and team members engaged for the long run.

3. Design

In this era, good user experience design is key to a successful product. We design interfaces (hardware and software) based on a number of use cases.

4. Execution

Applying agile methodologies, I work with your team through productive and fun relationships as we bring our vision to life—and to market.

Case studies.


As a premium LED components supplier serving a wide variety of customers, LUXTECH's LED supply chain was growing in complexity. At the same time, it sought to be the leader in human-centric lighting components. I worked with the LUXTECH team to move the supply chain to almost exclusively 90+ CRI LEDs while reducing costs compared to having both 80+ and 90+ CRI. As a side effect, availability and quality improved from higher quantities and better LED bins in stock.


dlux was one of the first circadian lighting controls companies. One of our partners had developed a ZigBee radio system for wireless control of tunable white lighting, but needed controls for automatic color changes. I customized our lighting control backbone to their specific system and was the product manager for a team of five overseas developers working on the lighting control web console. As the product was highly technical and development-intensive, I mitigated scope creep and employed an agile management process.

Bedtime Bulb

Bedtime Bulb is a new human-centric lighting product to be released in mid-2018. Because the product serves a niche not previously occupied, significant market research was needed to de-risk the investment and answer key product and marketing questions. Working with my business partner, a product expert, we conducted in-person and online surveys, resulting in over 8,500 data points. Some results were surprising—influencing the product and marketing direction in ways that would not have come from sheer intuition.
