Sylvania T8 Linear 23014 (F18T8/CW) Fluorescent Lamp — 18W | 4200K Cool White | 1,190 Lumens | 24-Inch Class Preheat Tube

The Sylvania T8 Linear 23014 (F18T8/CW) Lamp is a commercial-grade, medium-efficacy low-pressure gas-discharge fluorescent tube engineered exclusively for 24-inch under-cabinet task fixtures, industrial appliance illumination panels, retail display cases, and low-profile commercial utility strip brackets. Delivering 1,190 initial lumens of crisp 4200K cool white light, this 18-watt linear lamp utilizes a specialized internal phosphor blend to map a stable color rendering baseline of 60 CRI. Outfitted with an industry-standard G13 medium bi-pin base and engineered around a low-mercury configuration, it ensures an extended 7,500-hour rated average service life when driven by certified preheat ballast networks.

ADL Supply Expert Application & Replacement Guide

The Sylvania F18T8/CW (Order Code 23014) linear lamp is an established architectural maintenance baseline specified universally across office task lighting zones, residential and commercial under-cabinet counters, food service display hot-cases, and automated vending machinery interiors. Providing a sharp 4200K cool white visual field profile, this intermediate spectrum cuts minor visual strain, throwing a crisp, high-contrast workspace illumination field that satisfies traditional utility standards while ensuring long-term lumen maintenance properties across localized luminaire tracks.

Critical Preheat Starting Circuit Configurations and Mandatory Glow Starter Links: Commercial property maintenance managers and electrical gaffers executing facility-wide re-lamping loops must observe clear system boundaries prior to checking out: this 24-inch linear tube is engineered strictly as a Preheat fluorescent mechanism and requires a separate, functioning glow starter button to ignite. It is completely incompatible with electronic or magnetic Rapid-Start ballast circuits.

When power enters the circuit loop, the lamp relies on an external FS-2 (or equivalent) glow starter to channel an initial pre-heating current loop across the internal tungsten filament cathodes. Once ionized to standard running equilibrium, the path requires a continuous, ballast-regulated **operating arc voltage of 55V AC to 57V AC at a running current draw of 0.370 Amperes**. Forcing this preheat bulb into an un-startered rapid-start socket will prompt continuous non-ignition flickering, inducing rapid cathode sputtering that instantly blackens and destroys the tube end seals.

Operation, Safety & Mounting Compliance

High-Frequency Magnetic Choke Line Stabilization

This standard 18W linear compact tube interfaces cleanly with legacy magnetic choke modules or high-efficiency electronic preheat starting networks. By utilizing an integrated starter loop to heat the cathode fields prior to strike, the control matrix balances underlying voltage ripples to counter terminal arc drift, maintaining a consistent cool white light quality across your localized display panels without generating acoustic line humming loops.
