Not all kitchens have the same look or feel, but there are similar rules to follow when you start your own kitchen renovation.
Halo fixtures can only be used on Halo tracks, Juno fixtures on Juno tracks and Lightolier fixtures on Lightolier tracks.
That doesn't mean you can only use fixtures from one of those manufacturers.
Your fixtures may not be compatible with any other track.
And, depending on the manufacturer, there may not be any other fixtures to choose from. There are plenty of options -- and prices -- for new tracks and fixtures.
Track lighting kits are available for $50 or less at the big box stores, and can run into hundreds of dollars.
