Jimbo,

That is deffiantly not how the bulbs should respond.  The first action to try is to ensure they are up to date on the firmware.  After confriming that I would recommending moving the bulbs to the other locations the bulbs that are working are in.  This will eliminate eviromental and distance related issues.  If they still have issues in those working postions (you can also put the working bulbs in the locations where the ones having issues are to rule out area as well) then the next step would be replacement.  As long as the bulbs are under 2 years old they would be covered by the warranty policy.
