My bowls cost $ 0.99 at a local store by a very very similar name. Cheaper means thinner metal, for our purposes the thinner the metal the better. I had great success finding inexpensive stainless steel bowls locally at restaurant supply stores and 'Dollar Stores'. Higher output bulbs are larger, sometimes much larger. The bulbs I used were 23W (100 watt equivalent) CFL's). For bigger bulbs, you need bigger reflectors. This provided a little more protection for the bulb from accidental bumps. My bowls were slightly more than 2-1/2 inches deep so when the reflector was finished the standard lamp bulb did not rise above the reflector rim. This was about as small as I could find without special ordering them. I used 1.2 qt mixing bowls with a 7 inch diameter. The ones with rounded sides give better results than the ones with sloped sides. AND Learn what to do before you break a CFL bulb! īowls come in various sizes and shapes. 4) Create and use this at your own risk! My CFL's don't get hot, but yours might. Remember to always dispose of them properly. Always handle them carefully with gloves and screw them in by the base rather than the bulb. Take care and use all appropriate safety procedures! 3) CFL bulbs are fragile and contain mercury vapor. 2) This project involves metal cutting and grinding. I needed 10-12 for my photography/videography light project, so decided to build my own and save some serious cash! Like almost all of my projects, I made it at TechShop! CAUTION! 1) This project is for 23W or less CFL's only! Incandescent lights get much hotter and will pose a fire risk. If you only need one or two, inexpensive shop lights are a probably better choice. To get the light heading in the right direction we need a reflector. This works great for table lamps, but not so well for photography or indoor horticulture. Compact Fluorescent Lamp (CFL) bulbs are designed to emit more light from the side than the top.
