Resurrecting this to share some information. I bought the LED strip that Greenman started this thread about. I also bought the transformer and the connectors that were listed at Amazon.
For my application I did not need the connectors as there is one included with the strip. We have three overhead niches for lack of the correct term at our condo. These are flat shelf-like areas recessed into the wall that have a vertical surface at the back that rises to the studio ceiling. They are for displaying items overhead. Purely decorative type stuff, I see no practical use for them.
I installed the strip in the LR niche. It turned out really nice as we have some vases and stuff up there some of which are translucent and the light shows through them. It was great at providing general lighting that we didn't have with the light bouncing off the ceiling and lighting the whole room.
Once I had them up there and evening fell, we realized that the light output was too bright. Simple I thought I'll dim them. That's when the fun started.
I can make a long story short by saying that these are not dimmable. The same company does however have a strip of the same length that's also warm white that is dimmable. I bought an LED driver, three wall switches, one rheostat type dimmer and spent a considerable amount of time on this before I decided to work smarter instead of harder and did some damn research.

The LED driver was expensive but I will need that. I will use one of the switches and have uses for the remaining two and the rheostat dimmer was $12 with shipping so the cash out isn't a big deal.
If anyone is thinking about using these and wants to dim them, I can go into it further at that point.
