Total Light® G4 LED Low Voltage Bulb

Product Overview

The Total Light TL-G4 LED lamp family provides replaceable low-voltage illumination for compatible landscape-lighting fixtures that use a G4 bi-pin socket. This shared product page allows customers to select the wattage and color temperature needed for a new installation or replacement. Available configurations include 2.5-watt and 3.5-watt lamps in either 2700K warm white or 3000K white.

The 2.5-watt option produces 185 lumens and is suited to applications where a lower light level is preferred. The 3.5-watt option produces 265 lumens for areas that need additional output. The 2700K selection creates a warmer appearance that coordinates well with brass fixtures, wood surfaces and traditional landscape designs. The 3000K option remains warm while providing a slightly cleaner, more neutral appearance. Matching color temperatures across nearby fixtures helps maintain a consistent nighttime presentation.

Each lamp operates on compatible 9V–15V AC/DC low-voltage systems and uses stainless-steel pins with a silica-gel-style body. The lamps are rated for 25,000 hours, include UV inhibitors and have a listed CRI of 80+. Light output can be adjusted with compatible Lutron magnetic dimmers. Before ordering, confirm that the fixture uses a replaceable G4 lamp, that the selected wattage is within the fixture rating and that the lamp fits without interfering with the lens or housing. For project quantities, direct links to matching 25- and 50-count packs are provided below.
