LED G4 lamps replace standard Halogen G4 capsule lamps. These lamps are some times physically bigger or are not oriented correctly for the fitting in question so choose your lamps with care using the filters etc.

The advantage of LED G4 lamps is their very long life and low energy use. In addition they are available in a choice of colours. if you need a dimmable lamp your choice is restricted so use the filter to limit your search to dimmable lamps.
