Surgical Light

I made my own glass mounted light source for dental use. I used a lithium ion battery for power and a LED with a 3 degree lens for light. The cord that runs power from the battery pack to the lamp was an old head phone cord that I cut the earbuds off. The lamp housing was a blood sugar test strip container that I cut down to size. the mounting bracket is a hose clamp that I cut and modified. The total cost twas about $175 for all the materials and tools needed to put it together. This is a substantial savings over the $600 student price for a comparable quality light from a dental manufacturer. It was a neat project that I had fun doing, I got to buy some tools and I learned a little about electrical wiring. I got the idea and a parts list from a thread on another message board for dentists. I am really pleased with the quality and lightweigtness of the lamp and if it ever brakes I will know how to fix it. I am considering building some more and selling them to my classmates and professors. If I decide to do this, I am going to file papers with the secratary of state and start an LLC.
