'Security' Lighting

The Campaign for Dark Skies (CfDS) have a good page with details of how to install a floodlight. They have an interactive image that shows the effect of the tilt of the light. In case you haven't already worked it out, the light works better if tilted down rather than up! They also point out that domestic security lighting can contain 500 Watt bulbs. This is in comparison to the bulbs used by lighthouses; around 1000 Watts. And finally, here is a quote from Lisa Simpson:

"Springfield! Turn off your lights! Nobody likes sickly orange barf glow!"
