“Corona” LED Replacement Bulb, Warm White, 10-30VDC (3.0W), G4 Socket, Back Pin

At 270 lumens, this is our brightest warm white G4 LED bulb. Proprietary PWM Constant-current drive and 21 x high output thermally-efficient SMD LEDs combine to give record setting output in a G4 form factor.  The extra wide diameter printed circuit board distributes the LEDs over a greater area making this the ideal choice for larger spots and fixtures.  Choose warm white for interiors and cool white for exterior applications.

Note: Check alignment of existing socket pin holes in your fixture. Fits vertical mounted sockets common in spots and reading lights.
