Sundays big project was to change the lights in the living area and the bedroom (overhead Lights) The lights that were in there were around 8-10" around and had four bulbs in them, With three way switches. We replace them with Circular Thinlight Florescent fixtures(model 109) from JC Whitney, though you can get the same fixture from most camping stores for $10.00 more.
Removal and installation was a piece of cake, simply unscrew the lamps, disconnect one wire and reinstall the new fixtures using one of the old holes and two new ones.
The lights seem to make about twice the light and it is much whiter, will be so much easier to read by.
Next on the agenda is to replace the fixture in the bathroom and then over the sink in the kitchen.
