Overview

The GE 85369 is a 100-watt high pressure sodium lamp built for commercial, industrial, and outdoor lighting applications where high lumen output and energy efficiency take priority over color rendering. Producing 9,500 lumens at a color temperature of 2,000 Kelvin, it delivers the characteristic warm golden-yellow light associated with HPS technology—commonly seen in street lighting, parking lots, security lighting, and warehouse environments. The ED23.5 bulb shape is a standard elongated design that fits a broad range of HPS luminaires.

The lamp uses an E39 mogul screw base, the standard large-format base for commercial HID fixtures, and requires a compatible 100-watt HPS ballast for operation. High pressure sodium lamps are valued for their high lumen-per-watt ratio and long service life, making them a cost-effective choice for applications that run for extended hours. The trade-off is a very low color rendering index, which means colors appear washed out under HPS light—making this lamp best suited for illumination tasks where visibility and coverage matter more than accurate color reproduction.

Pros & Cons

👍 Pros

  • 9,500 lumens from only 100 watts provides high lumen-per-watt efficiency
  • 2,000K warm white output is well-suited for outdoor and security lighting applications
  • ED23.5 bulb shape and E39 mogul base fit a wide range of standard HPS fixtures
  • High pressure sodium technology offers long lamp life compared to incandescent alternatives

👎 Cons

  • 2,000K color temperature produces a yellow-orange light with very poor color rendering, unsuitable for applications where color accuracy matters
  • Requires a compatible 100-watt HPS ballast, adding cost and complexity to installation
  • Not dimmable without specialized ballast equipment
  • Contains sodium and requires proper disposal procedures at end of life
