What do you get when you cross a dimmer switch, a curtain rod, an extension cord and 5 clamp lights? Cheap, practical and adjustable track lighting! Here is a simple and quick way to make highly adjustable ceiling lighting for under $50. This took me a morning to see through from beginning to end and was definitely a good investment all around. It amazed me how dark my studio was before I made this and has me wondering why I didn't do this sooner. It's fantastic to be able to take pictures at night without worrying about there being enough light for the camera. It's also great to generally be able to see what I am doing. Not to mention, it's able to be fully dimmed for a wide range of lighting applications.
Also, i really like your instructable style: Clear, concise text and lots of sensible photos to detail each individual step.
Volts Times Amps Equal Watts V*A=W, most power strips and extension cords are rated at 15Amps at 110 Volts so thats 1650 Watts. So if you are really afraid of the dark and want to get a tan you could use 5 300watt bulbs and still be under the limit of the the cords but the dimmer and the lamp housing may not handle all that power the heat wold damage the clamp lights and the dimmer can only handle 600watts so to keep it all within the limit of the switch and cost 5 100 watt bulbs would do the trick and damage nothing
