A brief history of Rigel Systems astronomy LED flashlight. From the Sanyo rechargeable to innovative Starlite and Skylite LED models. Discover how Leon and Linda Palmer revolutionized the market, leading to a legacy of innovation and quality in astronomy tools.
Astronomy Magazine has included the Rigel Systems Skylite Mini Customizable Astronomy Flashlight in their infamous Annual Star Products Guide for 2025 - which will appear in the October 2025 issue.
Astronomy LED flashlight: A brief history of Rigel Systems
In the early 1980s, the preferred choice for professional astronomers was the Sanyo rechargeable flashlight. This device, while innovative at the time, had limitations. It was a small, white rectangular device that could be plugged into a wall socket for recharging. It featured a slide switch to toggle between two light bulbs, one protected by a clear plastic lens and the other by a red plastic lens. Despite its popularity, the Sanyo flashlight fell short during long observing sessions, particularly in the cold winter nights, as its battery life was insufficient.
The Birth of Rigel Systems
A pivotal moment occurred in 1983 during Leon Palmer's observing trip to Kitt Peak. Frustrated by the Sanyo flashlight's limitations, Leon began to explore the potential of red LEDs for use in flashlights. Upon returning home, he experimented with red LEDs, electronics, and plastic, which led to the creation of the first LED flashlight, aptly named Starlite. The initial design was a homemade effort, with Leon crafting the cases from Styrene plastic in his kitchen oven. The first batch was sold out within 30 minutes at the Riverside Telescope Maker's Conference, indicating an untapped demand for such a product.
Evolution of the LED Flashlight
The development of the Starlite continued, with improvements in design and fabrication. A significant breakthrough came when Leon adapted a 9-volt flashlight to house the Starlite circuitry. This version included variable brightness control and marked the first profitable iteration of Starlite. As red LED technology improved, becoming ten times brighter, the demand for these flashlights increased. When white LEDs became available, Rigel Systems introduced Skylite, featuring a two-color LED configuration. This innovation paved the way for further enhancements and competition in the market.
Rigel Systems' Continued Innovation
Rigel Systems didn't stop at the Starlite and Skylite. As the market for LED flashlights expanded, the company introduced new features and products, such as water-resistant versions and models with easier-to-operate controls. They also diversified the range of LED colors offered, from infrared to ultraviolet. This commitment to innovation and quality helped Rigel Systems establish a strong presence in the astronomy community, with nearly 100 dealers worldwide.
Through perseverance and innovation, Rigel Systems transformed the landscape of astronomical flashlights. Their journey from a kitchen-based operation to an internationally recognized brand underscores the power of ingenuity and the importance of meeting the specific needs of a niche market. Their success story is not just about the development of a product but also about the resilience and vision of its founders.
Rigel Systems' legacy extends beyond the Starlite and Skylite. The company continued to innovate with products like PulsGuide, QuikFinder, and a line of focusing motor products, each starting as simple ideas in their garage and evolving into sophisticated tools for astronomers. The story of Rigel Systems is a testament to the impact of entrepreneurship in advancing technology and serving the needs of niche communities.
