Low Voltage Light Bulbs

Hatter

So I am doing a complete remodel on my own house and trying to do everything the first time through so I dont have to do it again for a long long long time. My wife likes those electric window candles up year round and I was trying to come up with a way to run them on low voltage to save money and keep them from getting hot to the touch /burning the shade. Is there any bulbs you would suggest? With a transformer, how many lights could I put on it - I wanted to link them all together and put them on a timer. Any transformer you would recommend? I am not extremely knowledgable about low voltage so any help would be appreciated.
Thanks

look into LED bulbs you can get them in a candle style and will use about 1 watt and last 30000 hours they are expensive though but pay for themselves.
