GE 22575 HR100DX38 100W Coated ED23.5 Mercury Vapor

The GE 22575 is a 100W mercury vapor HID lamp built for commercial and industrial area lighting applications requiring long service life in existing mercury vapor fixture installations. With ANSI H38/O classification, 4,000 initial lumens of 3900K output at 50 CRI, E39 mogul screw base, ED23.5 bulb shape, universal burn position, and open or enclosed fixture compatibility, this lamp is the direct replacement source for compatible H38-ballasted mercury vapor fixtures in parking lots, outdoor area lights, security lighting, and industrial high-bay applications where lamp-for-lamp replacement rather than fixture retrofit is the maintenance strategy.

ADL Supply Expert Application & Replacement Guide

The GE 22575 is a direct replacement lamp for existing H38-ballasted mercury vapor fixture installations — parking lot pole fixtures, outdoor security lights, industrial high-bay luminaires, and commercial area lighting systems where the existing ballast infrastructure and fixture housings are being maintained rather than replaced. Mercury vapor HID lamps produce a characteristic blue-white 3900K light with a CRI of 50, which provides adequate visibility for outdoor area and security applications but is significantly below the color rendering quality of metal halide or LED alternatives. The 30% lumen depreciation from initial (4,000 lm) to mean (2,800 lm) output is a normal characteristic of mercury vapor technology — facilities noticing reduced light levels over time should replace lamps to restore initial output, but should also evaluate whether a fixture retrofit to metal halide or LED is more cost-effective than continuing mercury vapor maintenance. This lamp requires a mercury vapor magnetic ballast specifically rated for ANSI H38 — metal halide, HPS, and other HID ballasts are not compatible even at the same wattage. Allow a warm-up period of several minutes to reach full lumen output from cold start, and a hot restrike cool-down interval before attempting re-ignition following a power interruption.

Before You Order

Operation, Safety & Mounting Compliance

Mercury Vapor Ballast Compatibility, Warm-Up & EISA Regulatory Status

Mercury vapor lamps require a dedicated mercury vapor magnetic ballast — the arc tube's starting and operating electrical characteristics are matched to the mercury vapor ballast's current-limiting and voltage output parameters. Metal halide and HPS ballasts are not electrically compatible and must not be substituted regardless of apparent wattage similarity. Allow several minutes warm-up from cold ignition before the lamp reaches stable lumen output. Following any power interruption allow a hot restrike cool-down interval before attempting re-ignition — normal HID behavior for mercury vapor. Note that general service mercury vapor lamps above 40W are restricted from manufacture and import for general lighting service in the United States under EISA 2007 — this lamp is available for replacement service in existing installations; confirm current availability and applicable regulatory status before placing large volume orders.

UV Safety, Mercury Content & Disposal

A cracked or damaged outer envelope on a mercury vapor lamp exposes UV radiation — replace damaged lamps immediately and avoid prolonged exposure in occupied areas. This lamp contains mercury and must be recycled through a certified lamp recycling program — do not discard in standard municipal solid waste. For certified recycler information visit lamprecycle.org. Verify California Title 20/T24 and Prop 65 requirements with the GE Lighting specification sheet. This product cannot be shipped to CA, CO, HI, ME, MN, OR, RI, or VT.
