I have replaced many of my often used incandescent light bulbs and all of my CFL spot lights with long life (22 year) LED light bulbs. The fact that the price of LED bulbs have come down significantly recently and the fact that they use far less electricity makes them a good choice. Just make sure you select 2700 K LED’s if you want them to look as warm as an incandescent bulb and choose a dimmable bulb if the switch has a dimmer.
I replaced my three 60 watt incandescent light bulbs on my outdoor lamp post with three candelabra base LED bulbs. Each bulbs is a 60 watt equivalent that only uses 6.5 watts. That is a total of only 19.5 watts of power consumption versus 180 watts. With the lamp post being on all night long, you would probably save some change after a short period of time.
Hope this helps.
