The Sulfur Lamp: Technical Page

The sulfur lamp is an efficient, powerful, bright, full spectrum light source that has many different indoor and outdoor uses. Each bulb contains a small amount of sulfur and inert argon gas. When the sulfur is bombarded by focused microwave energy it forms a plasma that glows very brightly, producing light very similar to sunlight. Because there are no filaments or other metal components to break down, the bulb may never need replacement. Only the magnetron needs changing!

The system is dimmable to 20% and provides a constant correlated color temperature of 5,700 degrees Kelvin with a color rendering index of 79. Again, because there are no filaments to degrade or alter its chemical composition, the light source will not change color or intensity over time and will continue to render objects close to their true color.
