Overview

The GE 26430 LUCALOX is a 250-watt high-pressure sodium lamp producing 28,000 initial lumens at a correlated color temperature of 2,100K. That translates to a luminous efficacy of 112 lumens per watt — among the highest of any HID lamp technology. The light it produces is the familiar amber-gold wash seen in street lighting, parking structures, and industrial yards. With a CRI of just 22, this is not a lamp for any environment where seeing color accurately matters. What it does provide is raw photometric output and longevity: the 24,000-hour rated life means years of service in fixtures that run on dusk-to-dawn photocell schedules. The clear ED18 envelope sits on an E39 mogul base, compatible with standard commercial HPS luminaires.

This lamp requires an ANSI S50-rated 250W HPS ballast — magnetic reactor or electronic — and cannot be operated on ballasts designed for metal halide or mercury vapor lamps. Warm-up to full output takes approximately 3-5 minutes, and restrike after a power interruption requires roughly a minute for the arc tube to cool before reignition. These characteristics are standard across HPS technology and should be factored into any application where instant-on lighting is needed. The LUCALOX line has been a staple in commercial and municipal lighting for decades, and this 250W variant is sized for medium-scale area lighting — parking lots, loading docks, roadway fixtures, and security perimeter lighting where sheer output and operating cost matter most.

Pros & Cons

👍 Pros

  • 28,000 initial lumens from a 250W lamp delivers high luminous efficacy of 112 lumens per watt, making it one of the most energy-efficient HID options available.
  • 24,000-hour rated lamp life significantly reduces replacement frequency and maintenance costs in hard-to-access commercial fixtures.
  • Clear ED18 envelope with mogul base fits standard commercial HPS fixtures without modification or adapter.
  • 2,100K warm spectrum minimizes blue light scatter, providing effective illumination in fog, dust, and haze conditions common in outdoor industrial settings.
  • Proven high-pressure sodium technology requires no warm-up period beyond the standard 3-5 minute ignition cycle and delivers stable output throughout its rated life.

👎 Cons

  • CRI of 22 renders colors extremely poorly, making this bulb unsuitable for any application requiring accurate color discrimination such as retail, signage, or security camera identification.
  • Requires a dedicated 250W HPS ballast, adding cost and complexity to initial installation compared to direct-wire LED alternatives.
  • 3-5 minute warm-up to full brightness and restrike delay after power interruption make it impractical for applications requiring instant-on illumination.
  • Contains mercury and sodium, requiring proper hazardous waste disposal at end of life — it cannot be discarded in standard waste streams.
  • The narrow amber spectrum cannot be filtered or corrected to produce white light, limiting its use strictly to applications where color quality is irrelevant.

Frequently Asked Questions

The CRI is 22, which is extremely low. High-pressure sodium lamps produce a narrow-spectrum amber-gold light that renders colors very poorly — reds and greens will appear muted or indistinguishable. This bulb is designed for area illumination where lumen output and lamp life matter more than color accuracy, such as roadways, parking lots, and security lighting.
This is a 250W high-pressure sodium lamp that requires a compatible 250W HPS ballast (typically an ANSI S50 reactor or electronic equivalent). It cannot be operated on a metal halide or mercury vapor ballast, and running it without the correct ballast will damage the lamp or prevent ignition entirely.
HPS lamps typically require 3-5 minutes to reach full output after the initial arc strike. If power is interrupted, a restrike period of approximately 1 minute is needed before the lamp can reignite. This warm-up characteristic is inherent to all high-pressure sodium technology.
The E39 mogul base is significantly larger than a standard E26 household socket. It is used exclusively in commercial and industrial fixtures designed for HID lamps. This bulb will not physically fit a standard household lamp socket.
2,100K produces the characteristic amber-gold glow associated with street lighting and industrial area lights. It is far warmer than any residential LED or incandescent lamp and has almost no blue content, which makes it effective for reducing light scatter in foggy or dusty environments.
