Philips MainsFit LED T8 Tube Installation Guide

Direct Connection to AC Line Voltage (120-277V)

Product Overview

Unlike fluorescent lamps that require a ballast to provide lighting, the Philips MainsFit LED tube is designed for operation on AC line voltage (120-277V) without the need for a ballast or driver. This guide provides essential installation steps for the proper and safe operation and installation of Philips MainsFit LED tubes.

For questions or comments, please contact Signify at 1 800-555-0050 (USA) or 1 800-668-9008 (Canada).

The Philips MainsFit LED tube is suitable for replacing fluorescent lamps (T8 or T12) in fixtures with G13, FA8, or R17d type sockets.

Compliance: RoHS compliant, UL/CUL certified.

LED Conversion Instructions

Before installation, ensure power to the fixture is switched off at the circuit breaker panel.
Remove the fluorescent lamps and the ballast compartment cover from the fixture.
Cut all wires connected to the ballast. Cut wires as close to the ballast as possible, as they will be reused.
Ensure sockets are in good condition, free from corrosion or discoloration, and securely mounted. Sockets should ideally be shunted (most common with instant-start ballasts). If sockets are not shunted, they can be used by adding a jumper wire to short the two terminals (see diagram).
The Philips MainsFit LED tube is double-ended, requiring AC power from each side. Connect the phase wire of the AC line (typically black) to one socket and the neutral wire (typically white) to the socket on the opposite side.
Note: All connections and unused wires must be properly capped. Ensure the fixture remains adequately grounded.
Close the ballast compartment using the cover removed in step 2. Apply the provided sticker in a visible location on the fixture to inform installers that the fixture has been modified for LED conversion.
Install the Philips MainsFit LED tube into the sockets. Ensure the tube pins are securely seated in the sockets.
Turn on the fixture power.

Fixture Description and Requirements

Philips T8 LED tubes cannot be used for LED conversion of existing fluorescent fixtures that use a remote starter.

Please ensure the dimensions of the existing fixture are not less than the dimensions indicated in the table below.

Philips LED T8 Tube for Retrofit	Fixture Dimensions with Maximum Tubes (Length x Width x Height in cm)
Maximum of 6 LED tubes (48 in.) in a fixture with or without a diffuser	123 x 58 x 8.2 cm
2 tubes, 96 in.	244 x 12 x 8 cm

Note: It is recommended to convert all fluorescent lamps to LED T8 tubes within a fixture. Applying a sticker to a partially converted fixture to LED may communicate a misleading message to future installers.

Diagrams and Wiring

Diagram 1: Ballast Bypass for LED Conversion

Diagram illustrating ballast bypass for LED conversion. Shows a fluorescent fixture with two lamps and a ballast. The ballast wires are disconnected, and the LED tube is wired directly to the AC line voltage at the sockets.

(Original text: The figure corresponds to two lamps and one ballast. For other configurations, please contact Philips Lighting.)

Diagram 2: Socket Conversion (Shunt)

Diagram showing how to convert a non-shunted socket to a shunted socket by adding a jumper wire. This ensures proper connection for the double-ended LED tube.

(Original text: The figure shows how to modify a socket without shunt to a socket with shunt using a jumper wire.)

Important Warnings and Safety Information

Risk of fire or electric shock. The rated voltage of these products is 120~277 V; the installer must determine if 120~277 V is present at the fixture before proceeding with installation.
Risk of fire or electric shock. Fixture wiring, ballasts, or other electrical parts may be damaged during installation of reflector assembly hardware. Check wiring and included components.
Risk of fire or electric shock. Installation of the LED conversion kit requires knowledge of fluorescent luminaire electrical systems. If not qualified, do not attempt installation. Please contact a qualified electrician.
WARNING - RISK OF FIRE OR ELECTRIC SHOCK. INSTALL THIS KIT ONLY IN LUMINAIRES THAT ARE ILLUSTRATED IN THE PHOTOGRAPHS AND/OR DRAWINGS AND WHERE THE MARKING OF THE RETROFIT KIT DOES NOT EXCEED THE LUMINAIRE'S INPUT RATING.
To prevent damage or abrasion, do not expose wiring to sharp edges of sheet metal or other sharp objects.
During installation of the conversion kit, do not make or alter any open holes in an enclosure of wiring or electrical components.
Before proceeding with the modification kit installation, the installer should examine all parts not intended to be replaced by the modification kit, ensure no parts are damaged, and replace any damaged parts.
Installers should not disconnect existing wires from socket terminals to make new connections to socket terminals. Installers should cut existing wires from the socket and make new connections to the socket wires using applicable connectors.
THE RETROFIT KIT IS ACCEPTED AS A COMPONENT OF A LUMINAIRE FOR WHICH THE SUITABILITY OF THE COMBINATION SHALL BE DETERMINED BY THE AUTHORITIES HAVING JURISDICTION. THIS PRODUCT MUST BE INSTALLED BY A QUALIFIED ELECTRICIAN IN ACCORDANCE WITH ALL APPLICABLE ELECTRICAL CODES. THE INSTALLATION GUIDE DOES NOT SUPERSEDE LOCAL OR NATIONAL ELECTRICAL INSTALLATION REGULATIONS.

Suitability: Suitable for dry or damp locations.
