Adafruit Industries has created a tutorial to upgrade an ordinary trampoline by adding fun, interactive NeoPixel LEDs.
This is a really fun project that lights up when you jump on it! These trampolines are meant for exercising and jumping on this thing for just a few minutes feels like a working out so perfect for tiring out kids, just be sure to supervise them. It works really well and looks amazing at night, especially around a fire pit with a fog machine.

I bought a pair of these magnetic clip lights last year and they've proven to be incredibly useful when I have to do repair work. The light has 8 LEDs and it throws a pretty wide beam of bright light. It sticks securely to any ferrous metal surface and has a clip so you can attach it to your pocket. I used it recently when I was installing a new safety switch in a washing machine. I stuck it on the side of the washing machine cabinet and it gave me plenty of light to attach the ground wire and route the cable. I haven't had to change the batteries yet, either.
The price is right, too. A set of 2 costs $(removed) on Amazon.

TCP is selling a six-pack of 65 Watt equivalent flood light LED bulbs for $(removed) on Amazon. (Dimmable bulbs are available too, for $(removed) a bulb). Read the rest
