Product Overview

SYLVANIA 23478 | F30T12/D/RS 30W 36" T12 Rapid Start Fluorescent Lamp
The Sylvania 23478 (F30T12/D/RS) is a commercial-grade **30W linear fluorescent lamp** engineered for high-visibility industrial, workshop, and retail spaces. Measuring exactly **36 inches (3 feet)** in length, this classic T12 tube utilizes an advanced **Rapid Start ignition system** to deliver instantaneous, flicker-free illumination when paired with compatible electromagnetic or electronic ballasts. Producing **1900 initial lumens** of crisp, vibrant **6500K Daylight** light, this tube offers an extended rated average lifespan of up to **18,000 hours** through a standard G13 Medium Bi-Pin base configuration.
| Wattage / Length 30W / 36" T12 (1.5" Diameter) | Brightness 1900 lm 6500K Daylight | Base Type G13 Medium Bi-Pin | Rated Life 18,000h Rapid Start Series |
Vibrant Daylight Illumination and Calibrated Performance
Sylvania T12 linear fluorescent lamps are manufactured to strict industrial standards to ensure consistent electrical loading and steady lumen maintenance over time. At a **6500K color temperature**, this tube supplies a cool, alertness-promoting spectrum that closely replicates natural mid-day sun, which helps combat fatigue in high-focus commercial zones. To achieve optimal performance, this lamp should be paired with ballasts complying with **ANSI C78.81** specifications.
- Rapid Start Engineering: Built to activate quickly and smoothly, minimizing initial ignition wear on the internal cathodes.
- High Maintenance Retention: Delivers a strong **1615 mean lumens** throughout its operational lifespan, keeping workspace light levels uniform.
- Lifespan Calibration: The 18,000-hour rating is established on standard 3-hour operational burn cycles. Running the lamp on longer, continuous cycles further increases average lifespan.
- Sturdy 1.5" Profile: Features a thick, rigid T12 structural profile that handles temperature fluctuations well inside rugged utility environments.
