I had 3 glass pendants over the kitchen island.  The problem with glass is the light is not directed downward and can be glaring to the eyes.  These lights not only direct downward but can you can put up to 100 watts and they are dimmable.  I currently have a 60 watt in each and the light is perfect.  The only negative is when installing the light getting them all even is very challenging because you have to take the wiring out of the box..no problem if you are only installing one
