Lights on the inside

I have started changing the lights inside the Cat to Led's I have changed the 21 lights in the main living area. They are 1 watt models giving the light equivalent of a 10 watt halogen. With all 21 lights on, the light is not too bad (her in doors does not quite agree). But they only use the power of 1 21watt tungsten bulb, so are a lot more economical on the battery when there is no mains power supply available. I will look into obtaining some 2watt one for the next 12 that I need that way I can adjust the light a little, so that I can get into the good books of her in doors.
