The T3-COB G4 Bi-Pin Base LED bulb delivers warm, inviting light in a compact, field-ready package. Designed to retrofit JC10/G4 bi-pin incandescent and halogen fixtures, this 12V LED replaces old bulbs with a modern COB source that trims energy use while preserving brightness and ambiance. Available in 2700K and 3000K, it fills spaces with a natural, cozy glow perfect for intimate interiors and outdoor accents alike.

Key benefits that matter

  • 360° beam pattern for truly even illumination in fixtures where light needs to reach every corner no dark spots in cabinet, indicator, or reading lights.

  • G4 Bi-Pin base compatible with existing JC10 bi-pin sockets for a simple retrofit no rewiring required in most setups.
  • Dimmable with magnetic transformer for smooth, flicker-free light in dimming applications, from mood lighting to task illumination.

Why this matters for your space

Choosing the T3-COB G4 Bi-Pin LED means less energy draw, cooler operation, and fewer replacements without sacrificing brightness or mood. The 360° light distribution ensures every fixture, cabinet, or exterior niche is evenly lit—ideal for tight installations where traditional directional bulbs can leave shadows. The combination of 2700K/3000K options gives you precise warmth to match existing decor, whether you’re upgrading cabin lighting on an RV or adding a soft, inviting glow to a boat galley or landscape path.

Installation tips and best practices

  • Use with a compatible magnetic transformer to enable smooth dimming and avoid flicker.
  • Confirm your fixture is within the 9–18V AC/DC range for stable operation.
  • For outdoor or damp locations, rely on the IP67 rating to protect against water ingress and dust.
  • When retrofitting, verify the JC10/G4 bi-pin socket compatibility and ensure the fixture has adequate clearance for the 360° beam.
