You do not need distilled water for your Keurig. Some people will use filtered water from a Brita, etc. but you really don't even need to do that. I use tap water. I don't remember what the set up for the small sized machines are, but if yours has a tank, it comes with a replaceable filter and instructions on how to "descale" the machine periodically (I use vinegar instead of their expensive solution). That should be enough.

Do you like your new lamp?
