It doesn't happen often, but on our last trip, BJ mentioned she'd like to have a light in the storage area in the loft, and one over the sink in the bathroom. I could have installed more strip light in the storage area, but instead we headed to the big blue box store to see what they recommended. We quickly honed in on the Striberg lights complete with switch and sensor. I was going to use the Dioder set, but they didn't look as clean.
14" long Striberg lights (the shortest version) have five LEDs housed in an aluminum housing. The light assembly uses 12 volt DC making the included transformer unnecessary - it makes for an easy installation. I practiced with the one mounting to the bottom of the shelf with the wiring running up through holes in the top and bottom of the hollow shelf to tie into the stock light.
It's time to test. BJ says she's camped enough this summer, so I'm off chilling in Colorado and testing the latest improvement.
