..... One has two 150 w halogen floodlight, The other is a single switch to 4 - 150 w incandescent light fixtures.
Wow! (
I am a big fan of outside light as part of security)...
I am impressed. But unless my math fails me.. that's 900 watts of electric being consumed. If your running those lights dusk to dawn.. that should be over $700 a year (much more on the left coast). I am
not into saving the planet...
but money... that's a nearly nonrenewable resource.
This could be a great time to look at the X10 Floodlights (PR511) or even the FloodCam (VR38A). You can reduce the wattage of the bulbs greatly (even use some CFL and/or LED lights) as well as have lights (and a chime) come on it the home when motion around the garage is detected. This project could increase security AND save money.
But... be warned: X10 and Home Automation in general is addictive. Any saving could be reduced or exhausted with other projects. I use a complete [X10] perimeter detection setup (as well as driveway alert). I use lights, chimes, and Voice Announcements to alert myself...
and warn away potential intruders. This can be seen near the end of
my X10 - BVC YouTube Video.
(YouTube Videos is gooder than readin.)
