PHILIPS 22W TL5C FC9T5/841 4100K Cool White | 9-Inch Circline T5 | 2GX13 4-Pin Base

Philips TL5 Circular 22W/840 (Order Code: 16600-9) is a slim, high-efficiency T5 circline fluorescent lamp. Delivering a bright 4100K cool white light in a compact 9-inch diameter, this lamp is designed for decorative and architectural luminaires where space is limited but high light output is required.

Product Overview

The Philips Master TL5 Circular series is engineered for high-performance ceiling and wall-mounted fixtures. At only 5/8" in tube diameter (T5), this lamp allows for extremely low-profile fixture designs. The 4100K cool white light provides a crisp, professional appearance that is well-suited for kitchens, hallways, and office spaces. With its circular shape, it provides omnidirectional light distribution, eliminating the shadows often found with linear lamps in round fixtures.

• High-Quality Phosphors: An 85 CRI ensures that interior colors look natural and vibrant under the cool white light.
• Slim T5 Technology: The reduced tube diameter (16mm) compared to standard T9 circline lamps results in a higher system efficiency and sleeker aesthetic.
• Symmetrical Light Distribution: The circular design provides uniform illumination, making it ideal for shallow, modern luminaires.
• Reliable Ignition: Designed for use with electronic ballasts to ensure flicker-free starting and consistent lumen output.

Before You Order

• Base Compatibility: This lamp features the 2GX13 4-pin base. Please note that the pins are arranged in a specific circular pattern that is different from standard 4-pin plug-in lamps or T9 circline lamps.
• Size Verification: This is a 9-inch diameter lamp. Measure your fixture's available space carefully, as circline lamps come in multiple diameters (e.g., 9", 11", 12") that are not interchangeable.
• Ballast Requirement: Requires a compatible electronic T5 circline ballast. It is not designed for direct-wire application.
• CCT Preference: 4100K is a cool white light. If you are looking for a warmer, more yellow light for residential living areas, search for the 3000K (830) version of this lamp.

Additional Information

Philips TL5 Circular lamps are a preferred choice for high-end European-style fixtures and modern commercial lighting. Their compact size and high lumen density make them a reliable replacement for maintaining original architectural lighting designs. For those looking to upgrade to LED, ensure that the retrofit solution is specifically designed to bypass the existing T5 electronic ballast or is compatible with the 2GX13 socket configuration.
