GE 48863 F57QBX/835/A/4P/EOL

GE F57QBX/835/A/4P/EOL 48863 — 57W Quad Biax Q/E High Output CFL, 3500K, GX24q-5 4-Pin

The GE F57QBX/835/A/4P/EOL (Order Code 48863) is a 57-watt Quad Biax Q/E High Output compact fluorescent lamp from GE Lighting's Ecolux series, using amalgam technology for stable light output regardless of burning position. This T4 quad-tube CFL delivers 4,300 initial lumens at 3500K natural white with 82 CRI, a 4-pin GX24q-5 base, and a rated life of 17,000–20,000 hours depending on switching cycle. Designed for high bay industrial, retail, and commercial applications. Requires a compatible electronic ballast rated for 57W GX24q-5 lamps — verify ballast compatibility before ordering.

Technical Specifications

Product Overview

The GE F57QBX/835/A/4P/EOL uses amalgam technology, replacing the liquid mercury found in standard CFLs with a solid mercury-alloy amalgam. This stabilizes light output regardless of burning position — horizontal, vertical, or base up/down all deliver the same output, unlike standard CFLs which can lose significant lumen output in unfavorable orientations. The amalgam design also extends the usable operating temperature range, maintaining 90% light output from -10°C to +55°C, making this lamp suitable for outdoor canopy and other temperature-variable applications where standard CFLs would underperform.

This lamp includes built-in end-of-life (EOL) protection using a titanium-hydride safety system, and must be operated only with EOL-equipped electronic ballasts. The 4-pin GX24q-5 base is designed for high-frequency electronic ballast operation only — this lamp is not compatible with magnetic ballasts. The ultra-compact quad-tube design allows this 57W, 4,300-lumen lamp to fit into smaller luminaires than older twin-tube CFL designs of comparable output.

Compatible Applications

• High bay industrial lighting — High lumen output and wide operating temperature range suit warehouse and industrial ceiling fixtures.
• Arena and sports facilities — Stable output and long rated life for large commercial venues.
• Outdoor canopy lighting — Wide -10°C to +55°C operating range supports outdoor temperature variation.
• Big box retail and commercial ceiling fixtures — High output CFL for large-format retail spaces.
• Reception areas, lobbies, and office buildings — Natural white 3500K with good color rendering for general commercial use.
• Parking garages — Wide temperature tolerance and universal burn position suit varied garage fixture orientations.
• Schools and healthcare facilities — General-purpose commercial lighting application.

Before Ordering — Verify

• Ballast Compatibility: This lamp requires an electronic ballast rated specifically for 57W GX24q-5 lamps with end-of-life (EOL) protection. A 42W-rated ballast may not provide proper operation — confirm ballast wattage rating matches 57W before ordering.
• Ballast Type: Confirm your ballast is electronic, not magnetic — this lamp is not compatible with magnetic ballast systems.
• Base Type: Confirm fixture socket accepts GX24q-5 (4-pin).
• Switching Cycle Expectations: Rated life varies by switching frequency — 17,000 hours on a 3-hour cycle versus 20,000 hours on a 12-hour cycle. Consider your application's typical on/off pattern.
• Physical Fit: Confirm 7.11" MOL and 2.3" diameter fit within your fixture's lamp compartment.

Safety and Handling Guidelines

• Electronic Ballast Only: Do not use with magnetic ballasts. Operate only with EOL-protection-equipped electronic ballasts rated for this lamp.
• Maximum Cap Temperature: 140°C — confirm fixture ventilation supports this rating.
• Maximum Preheat Current: 0.55A.
• If the Lamp Breaks: Ventilate the area for 30 minutes before cleanup. Contains mercury amalgam — follow standard CFL breakage cleanup procedures.
• Allow Cooling: Allow the lamp to cool before handling or replacement.
• Disconnect Power: Turn off power before installing or removing the lamp.

Compliance

• Contains 3.0 mg mercury (amalgam) — dispose of properly per local regulations. This product cannot be shipped to CA, CO, HI, ME, MN, OR, RI, or VT due to state mercury lamp regulations.
• EU Energy Class B.
• Low-mercury amalgam design — may qualify for LEED-EB MR Credit; verify current LEED criteria and project requirements independently, as LEED standards are updated periodically.
• Verify RoHS and additional compliance details with the GE manufacturer specification sheet prior to use in regulated installations.
