So I promised to "come clean" as to what happens if you push the little camera power supplies to their limits driving LED light strips. Well....its quirky, but not what you think. Turns out if these little 12v camera power supplies are operated at their upper limits (AKA past their upper limits), they become hyper-sensitive to their house code!
What happened is...they were on code "K" which is the kitchen. BUT because the pantry door is also on a "K" code and its opened and closed frequently, the little X10 warts would frequently decide that random powerline activity on their "home" house code meant...TURN OFF. And so they would. Two or more openings of the pantry and they'd shut off unpredictably but invariably at some random point. Didn't matter whether the pantry door light was commanded ON or OFF either...just any activity on their housecode would convince them it was time to turn OFF!
To prove my theory I put them on a second house code that also has motion sensors that are fairly active - and sure enough, they'd shut off randomly.
The solution was simple - I put them on one of my house codes that has no motion sensors; and tadaaaa.....they are reliable and fully functional. Curious, huh?
