Hey Sailingrose:  We have had Solatubes for about 12 years or so.  One in our powder room and one in a dark hallway.  They work great&#33;&#33;  Except in the beginning I kept trying to turn off the light in the powder room.  <img src="http://www.cruisecrazies.com/community/images/forum/tr-emoticons/rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes2:" border="0" alt="rolleyes.gif" />   As I recall they were installed in about three hours and have been no problem.<br /><br />
