The other item that I had bought came in the mail awhile ago, but finally found the perfect spot to put them--in my overhead lighting, which I normally don't use. These are color changing bulbs that can be put in a regular socket, but are changed with a remote control. They have low wattage, so they're environmentally friendly, and they (supposedly) have a long battery life--51,000 hrs. Also, there are 16 colors (derived from various combos of red, green, and blue), as well as 4 settings that can rotate through them.
The other awesome thing about them is that they're rather cheap right now on Amazon--$4.40 as of today, which is a bit cheaper than a normal party light bulb. The only downside to them so far is that they're not particularly bright--of course, if you live for the ambient lighting like I do, that's not so much of a deterrent. I showed them to Sam, and much excitement ensued. So we've now bulk ordered a bunch and I think much of the house will soon be one giant rainbow.
**UPDATE** The bulk package of bulbs has arrived! Now the 'rainbowing' of the house may commence!
