Side-Mount Bi-Pin G4 LED Bulbs

In general, you should select a G4 LED bulb replacement bulb which has the LEDs facing the direction in which you want the light to throw. While your original incandescent bulb was isotropic (omni-directional), these LEDs benefit by being directional, so are much more efficient with the LEDs facing toward the surface to be illuminated. 

All of our products will match up against a 10W halogen or Xenon G4 bulb, but will use 85% less energy, last longer, and produce less heat.
