I think 100 W incandescent are too bright; I use 5 W incandescent lights (usually only one at a time, sometimes two if one is insufficient). I also find LED lighting (and flurescent) to be irritating (and they actually use a bit more power, the LED lighting that they installed (but I removed) uses 8 W instead of the 5 W that the incandescent light uses), so I don't use them.

However, I think that often you should not need to be overly reliant on electric power. If you have enough windows then you should not need electric light in the day time, if the incandescent light in the winter time also provides heat, if you have candles when needed, moon light (depending on the phase of the moon), etc, and I can write by hand and many things can be done without a computer (including, walk to where you need to go; I do not have a car so I walk if it is close enough or car pooling with someone else if far away), there is sweater and blankets and candles (which also provide light) in case you are cold in the winter time, etc. If you learn to work things without electric power too then it avoids some of the overly reliance on it.

Getting rid of the roads for cars (and the cars) would also have some advantages (it would need more walking and others but those things can help, anyways).
