PHILIPS 40W F40T12/C50 Supreme/ALTO 5000K | T12 Linear Fluorescent | G13 Medium Bi-Pin

Philips F40T12/C50 Supreme/ALTO (Order Code: 42389-7) is a high-performance 48-inch linear fluorescent lamp. Engineered with a 90 CRI and 5000K daylight color temperature, it provides exceptional color accuracy and brightness, making it a premier choice for environments where visual detail and clarity are paramount.

Product Overview

The Philips Supreme T12 series is designed for users who refuse to compromise on light quality. While many standard T12 lamps offer lower color rendering, the C50 Supreme model utilizes advanced phosphors to achieve a CRI of 90, closely mimicking natural daylight. This makes it ideal for retail galleries, laboratories, and workshops where distinguishing between colors is vital. Built with ALTO® technology, these lamps contain less mercury than standard fluorescents, helping facilities meet environmental compliance standards.

• Supreme Color Accuracy: Features a 90 CRI that enhances the appearance of products, artwork, and technical materials by revealing true colors.
• Daylight Clarity: The 5000K color temperature creates a high-energy, "cool" environment that helps reduce eye strain and improves focus in work-heavy settings.
• ALTO® Low-Mercury Technology: Environmentally responsible design that simplifies disposal and supports green building initiatives.
• Extended Life: A 20,000-hour rated average life ensures long-term reliability in commercial and industrial fixtures.

Before You Order

• Ballast Compatibility: This is a T12 lamp. Ensure your fixture is equipped with a 40W T12 ballast. This lamp is not directly compatible with standard T8 electronic ballasts unless the ballast specifically lists F40T12 as a supported lamp type.
• Diameter Verification: T12 tubes are 1.5 inches in diameter. They are thicker than the standard 1-inch T8 tubes. Verify that your fixture's lampholders and clearance can accommodate the larger T12 size.
• Lighting Tone: 5000K provides a very crisp, blue-white light. For a softer, more residential feel, consider a 3000K or 4100K alternative.
• Recycling: As a fluorescent lamp containing mercury, it should be recycled according to local hazardous waste regulations at the end of its life.

Additional Information

Philips Supreme/ALTO T12 lamps remain a staple for maintenance and retrofits in established commercial facilities. Their high color rendering makes them a specialized upgrade over generic "Cool White" T12 lamps. For facilities looking to eventually transition to energy-saving technology, these lamps provide the best possible light quality in legacy fixtures until a full LED conversion is implemented.
