I would once again encourage individuals with a Solitaire to check out converting it to an LED. It appears to be one of the easiest incandescent to LED conversion possible. One advantage to using the Solitaire over Photons or Photons look-a-likes is the ease of obtaining and replacing the batteries. I have both lights and like the construction and on/off design of the solitaire. Also if you have a Mini-Mag light, the 3 LED Opalec replacement (http://www.brightguy.com/prod_results.tpl other companies also have the LED conversion module). It works really well and is real easy to do. I bought 2 recently and bought 2 new (my older ones were not compatible for conversion) Mini-Mags at a Target store that put on clearance the silver version for around $6.00, so for less than $30.00, I have a 3 LED light, that is great.
