Try incandescent lights or LED lights. Incandescents are really cheap now.

yeah, using small lamp or two for reading or whatever activity requires light.

LED lighting would be ideal for Claudine's house, but for more reasons than their higher efficiency. To run them on high voltage alternating current (like what's in the electric grid), the power has to be converted. In a new build with solar power, use LED fittings designed for low voltage DC instead of those that are designed to retrofit into older housing. Skip the energy loss from power conversion. Since that allows the LEDs to run cooler, it also extends their working lives.

My blog explains this and more about the state of the art in artificial lighting in easy to understand terms. The big holdbacks for LEDs have been cost, lack of intensity and poor quality of white light. The first two are rapidly improving. In a UK lab I have seen the solution to both intensity and light quality (very exciting!), but it isn't commercially available yet. When it becomes available I'll shout about it on my blog.


Familiarize yourself even with the terms that they use.
