SOX Lamp - Low Pressure Sodium Light – LPS Street Lighting Bulb

Genuine Low Pressure Sodium (LPS/SOX) lamps across all standard wattages — SOX-E 18W, SOX 35W, SOX-E 36W, SOX 55W, SOX 90W, and SOX 135W. Each lamp produces a near-monochromatic 589nm amber output with virtually zero blue light, delivering luminous efficacies up to 200 lm/W — the highest of any commercially available light source.

Trusted for infrastructure, dark-sky preservation, scientific research, and specialty applications where spectral purity and energy efficiency are critical.
