I recently had some lights installed and noticed they were not very bright -- almost like they were on a dimmer. I took out a bulb and noticed it was labeled 130V. Of course US is 120V so I'm not sure why a 130V would even be sold here. I'm guessing this is why they are so dim and I need to get a 120V bulb. The bulb is a Sylvania Capsylite Halogen 50W PAR30.
