Overview

The GE 26435 Multi-Vapor is a 400-watt metal halide lamp that produces 36,000 initial lumens at a 4,000K correlated color temperature. Compared to the amber monochromatic output of high-pressure sodium lamps, this bulb delivers full-spectrum white light that dramatically improves color rendering and visual acuity in commercial and industrial environments. The difference is immediately visible: signage becomes readable, product colors appear natural under retail lighting, and security camera footage captures usable detail. At roughly 90 lumens per watt, it is less efficient than an equivalent HPS lamp, but the qualitative improvement in light output often justifies the energy trade-off in applications where visibility quality matters.

The ED37 envelope with an E39 mogul base fits standard 400W HID fixtures, and GE positions this as a straightforward upgrade path from HPS — though ballast compatibility must be confirmed, as metal halide requires an M59-rated ballast rather than the S51 used for 400W HPS. The lamp is a point source, which means it works well in reflector-based fixtures that rely on optical control to direct light output. Warm-up time is 5-10 minutes with a 10-15 minute restrike delay, which is standard for metal halide technology. This lamp is built for warehouses, parking structures, retail big-box environments, sports facilities, and any large space where white light and high output are both required. As LED technology continues to advance, this lamp remains relevant for facilities with existing metal halide infrastructure that are not yet ready for a full LED retrofit.

Key Features

WHITE LIGHT METAL HALIDE BULBS: GE Multi-Vapor bulbs offer improved white light over high pressure sodium (HPS) bulbs. The bulb offers 36,000 Lumens with 4000K color temperature.

SIMPLE BULB CHANGE REQUIRED: In most cases, simply change your bulb to a Multi-Vapor metal halide light bulb to revolutionize your lighting.

HIGH EFFICIENCY METAL HALIDE LIGHT BULBS: These light bulbs will cost $177/year to operate in energy costs based on 3 hours of use per day.

LIGHT BULBS FOR COMMERCIAL AND INDUSTRIAL USE: The combination of high efficiency and long life make these HID metal halide light bulbs an ideal light source for many commercial and industrial applications.

METAL HALIDE LIGHT BULBS WITH GOOD OPTICAL CONTROL: Like incandescent light bulbs, these metal halide bulbs are a "point" light source, which allows for good optical control.

Pros & Cons

👍 Pros

  • 36,000 initial lumens at 4,000K provide high-output white light with substantially better color rendering than equivalent HPS lamps.
  • Point-source design in the ED37 envelope allows precise optical control in reflector-based fixtures, concentrating output where it is needed.
  • 400W metal halide operates at approximately 90 lumens per watt, delivering efficient high-intensity illumination for large commercial and industrial spaces.
  • 4,000K neutral white color temperature improves visibility for security cameras, retail displays, and any environment where color discrimination is important.
  • Compatible with existing 400W metal halide fixture infrastructure, reducing retrofit costs for facilities already wired for HID lighting.

👎 Cons

  • Higher operating cost than HPS at the same wattage — GE estimates $177 per year at 3 hours daily use, and actual commercial runtimes are typically much longer.
  • Metal halide lamps experience more significant lumen depreciation over their rated life compared to HPS, requiring more frequent group relamping.
  • 10-15 minute restrike time after power interruption is considerably longer than HPS, leaving spaces dark during outages without backup lighting.
  • Contains mercury and requires hazardous waste disposal at end of life, adding logistical and compliance costs.
  • 5-10 minute warm-up to full brightness makes this impractical for any application requiring instant-on illumination.

Frequently Asked Questions

At 4,000K, this metal halide lamp produces a neutral white light that renders colors far more accurately than the 2,100K amber output of HPS lamps. This makes it significantly better for retail displays, parking garages, and any application where people need to distinguish colors, read signage, or identify objects on security footage.
This 400W metal halide lamp requires an ANSI M59 pulse-start or probe-start compatible ballast rated for 400W metal halide operation. It cannot be run on an HPS or mercury vapor ballast. In many existing HPS fixtures, only the ballast needs to be swapped — GE markets this as a simple bulb change, but verify your ballast compatibility first.
Metal halide lamps typically require 5-10 minutes to warm up to full brightness. Restrike time after a power interruption is longer than HPS — approximately 10-15 minutes — as the arc tube must cool before reigniting. This is a critical consideration for applications where power interruptions are common.
GE rates this lamp for long service, but metal halide lamps experience more lumen depreciation over their life than HPS equivalents. Expect the 36,000 initial lumen output to decrease measurably by mid-life. Group relamping schedules are recommended rather than running lamps to failure.
The ED37 envelope with an E39 mogul base is the standard form factor for 400W HID lamps. It will physically fit any fixture designed for a 400W metal halide, HPS, or mercury vapor lamp of this shape — but again, the ballast must match the lamp type.
