One of the changes I am making to my home Halloween light show is the use of LED floodlights to replace the standard incandescent bulbs.
LED lights will use much less electricity than standard floodlights, saving both on our electrical bill, as well as making the light show less likely to trip a breaker. The downside to LED lights is that they have traditionally not been dimmable. These LED floodlights are designed to get around that limitation, for use in home lighting.
For those interested, these LED lights were purchased from WOWLights.com.
