I have gone to the site and see that these fixtures are made for use with LBL's monorail system. This is a different animal than the regular track lighting you have now.

You can call Juno's technical support line and see if they have something that will make the pendants work. I know that they make transformers from line to low voltage for single pendants. However, whether the LBL product will work with theirs is another question.

You may have to change out the track to LBL or return the lights. But before doing anything else, contact the technical support people to see what can be done.

I tried to get the 800 number for you but I couldn't get a connection to the website. However, you can find it at www.junolighting.com.

I hope this helps.
