This is Part 1 of a "How To" on making a homemade light fixture, consisting of vacuum tubes.
[IMPORTANT CREATOR'S NOTE] Many vacuum tubes contain toxic substances and gases (mercury, uranium, thoriated tungsten, etc.). You are well-advised to handle these valves with care, to ensure that they do not break, or react unsafely to the heat generated by the lighting. It is incumbent upon you to do the requisite research on each valve you employ, and by proceeding with this Instructable, you do hereby assume full responsibility for your actions, choices, and mishaps, and do hereby release the creator of any liability arising from your actions, choices, mishaps, or my design ideas. [END OF NOTE]
I own an LED lighting firm, and despite being on the bleeding edge of lighting technology, I have always been fascinated with vacuum tubes. Vacuum tubes, or thermoionic tubes (or valves) were the predecessors to transistors, integrated circuits, digital displays, etc. and were used from the 1920's all the way up through the fifties and sixties (some are still in use in some legacy equipment, and high-end audiophile stereo equipment). Their shapes conjure up images of the jetsons, and other fifties space-age movies and shows.
I wanted to make a light fixture that would adequately pay high homage to these fantastic relics, sparing no expense in making an art piece. Because the wattage required to light the heaters is so high (multiplied times seventy valves for this fixture!!), I opted out of making the streetlights dim in a 36-block radius, instead lighting them from underneath, using LED / lens modules from my own company's stock.
Step 1: Select and Purchase Your Vacuum Tubes
I first searched for the most unusual, exotic vacuum tubes available and ended up with a stunning selection of all sizes and shapes. I was lucky to find out that a gentleman in Santiago, Chile (the country where I live) is actually a world-famous collector and seller of vacuum tubes, with a breathtaking array of options.
Google "Francisco Mella tubos" and rest assured he ships worldwide in extremely well-protected packaging. Mr. Mella was exceedingly patient and accommodating of my uneducated questions, and unorthodox requests ("Send me pictures of your strangest specimens!")
