Illuminating Wellness: Tom Watson on Building TheraBulb and Logistics

About This Episode

Tom Watson didn't set out to build a product company. He was trying to help someone he cared about manage Lyme disease — a condition that affects a disproportionate number of people in Loudoun County. When infrared light therapy showed promise, Watson went looking for safe, certified bulbs and found only products designed for baby chickens and construction sites. That gap became Therabob.

The conversation covers the full arc of building a physical product business: finding overseas manufacturers, getting bulbs spec'd and RoHS certified, having every product independently tested at a U.S. military-grade laboratory, and navigating the economics of importing a 40-foot shipping container once a year. Watson is candid about the hidden costs — $15,000 and twelve months to develop a single bulb — and how he's kept retail prices at $30 to $35 despite tariff pressures by negotiating directly with manufacturers.

For Loudoun County entrepreneurs thinking about product-based businesses, Watson's story is a grounding reminder that what looks simple from the outside is rarely simple from the inside — and that solving a real local problem is still one of the most durable foundations for a business.

Key Topics Discussed

• Lyme disease as a local business catalyst — Watson explains that Lyme disease is a well-known issue in Loudoun County, and his firsthand experience searching for effective, safe infrared bulbs for a partner with the condition was the direct spark for Therabob.
• Overseas manufacturing and certification — Therabob sources large incandescent infrared bulbs from manufacturers in Asia, having them spec'd for specific wavelengths and irradiance levels, then RoHS and CE certified to ensure they are free of hazardous substances.
• Third-party laboratory testing — Every Therabob product is tested at a U.S. laboratory that also serves military and government clients, providing independent verification that competitors sourcing from retail channels cannot offer.
• Tariff navigation — Watson describes how Therabob avoided price increases during recent tariff pressures by working directly with manufacturers who had enough margin to absorb the added cost without passing it downstream.
• Low-cost market entry strategy — Watson's deliberate goal is to make infrared therapy accessible at $30 to $35 per bulb, positioning Therabob as the entry point for people who want to try infrared before committing to expensive home saunas.
• The real cost of product development — Watson details how bringing a single new bulb to market required approximately $15,000 in development and testing costs and took about a year, a reality invisible to customers who see only the final retail price.

Notable Quotes

"We spent, you know, $15,000 to actually come up with it... we spent a year, and then have it tested and then bring it in."

Watson was explaining why product businesses carry hidden costs that consumers never see when they look at a $30 item on a website.

"Our main goal is to be the low price entry point into starting infrared therapy. We want people to come and get a bulb for, like, $30, $35 dollars and try this out."

Watson describing Therabob's core market positioning relative to expensive infrared saunas and therapy centers.

"There's so much margin in there on the end of the manufacturers that they were able to work with us and bring the price down such that there was no increase in price due to tariffs."

Watson explaining how Therabob navigated recent tariff increases without raising prices for customers.

Local Business Takeaways

• Loudoun County's high prevalence of Lyme disease created a real, underserved demand for safe infrared therapy products — local problems can be the foundation for nationally scalable businesses.
• Entrepreneurs importing physical products should budget for development and certification costs that can reach $15,000 or more per SKU and plan for a timeline of a year or longer before a product is ready to sell.
• Building margin into your supply chain gives you negotiating power during economic disruptions like tariffs — Therabob absorbed cost increases without raising retail prices because the margin structure supported it.
• Third-party certification from a credible U.S. testing laboratory is a meaningful differentiator in health-adjacent product categories where buyers cannot easily verify safety claims on their own.
• Free shipping and accessible price points lower the barrier to trial, which is especially important when selling a product in a category — like infrared therapy — where many potential customers are skeptical or unfamiliar.
