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.

Note:  Check alignment of existing socket pin holes in your fixture.  If not horizontal, a realignment of socket may be necessary.

Replaces old item number ILSPG4-15W-B.
