Description

Upgrade your low-voltage lighting with SwitchToLED G4 LED Light Bulbs, engineered to replace traditional 20W halogen G4 bulbs while consuming just 3 watts of power. These bulbs emit a crisp cool white 6000K light, ideal for bright, clean illumination in cabinets, RVs, landscape fixtures, and display lighting.

Featuring a standard G4 JC bi-pin base and T3 shape, these bulbs are designed for easy installation in 12V AC/DC systems without rewiring. Built with advanced 3014 LED chips, they deliver consistent brightness (220–260 lumens), low heat output, and a long lifespan of 20,000+ hours, reducing maintenance and replacement costs.

SwitchToLED G4 bulbs are eco-friendly and safe, containing no mercury, lead, UV, or IR radiation. They are perfect for applications such as under-cabinet lighting, puck lights, RV interiors, landscape lighting, furniture lighting, display cases, and recessed fixtures.
