Because the standard electrode size is 18mm, and the cold-cathode tube is 25mm, the tube diameter must be matched somehow to the electrode. Every neon shop has all the other tools necessary for working large-diameter glass.Įlectrodes are attached differently to large- and small-diameter tubing. neon shops to sit down to work glass, but for precise work on large-diameter glass, sitting gives the necessary static position. The clamp can be fastened in any direction.įor electrode splicing, place the tube parallel to the table’s long side, approximately as high as your neck when sitting in front of the table. Always tighten the clamp thumbscrew gently when preparing a tube - if you hear a gentle crack, it’s too late. Use different clamp sizes, as the ones without plastic grip fingers (they get hot!) will tightly hold only a limited range of glass tubes. The tool of choice, standard in virtually every chemical laboratory, is a ring stand, with a heavy baseplate (a minimum of 8-10 lbs.) and a vertical iron rod to fasten the clamps. Handling large tubes isn’t as difficult as imagined. Cap the tubes and build a small roof on the rack’s top to prevent dust and soot from settling inside the tubes. If such space isn’t available, a vertical stock rack may be an option. Ideally, your floorspace should incorporate horizontal shelves for 8-ft. tall are necessary to avoid touching and breaking the lamps. ![]() Therefore, you need space to handle and process larger glass. In the United States, large neon tubes used for lighting measure 25mm in diameter and up to 8 ft. Gas-discharge lamps are a family of artificial light sources that generate light by sending an electric discharge through an ionized gas, a plasma. For this reason, the amount of energy transformed requires every part of the tube and installation to be adapted for high lumen-output light generation. Gas-discharge lamp Germicidal lamps are simple low-pressure mercury vapor discharges in a fused quartz envelope. The main purpose of a large neon tube is to generate a considerable amount of light, contrary to the main purposes of small tubes to be bent into intricate shapes and to light up in bright, saturated colors. I will refer to cold-cathode as "big diameter neon," whether it’s used for advertising, backlighting billboards or architectural lighting. In some European countries, where neon tubes have a standard diameter of 18 or 22mm, neon wouldn’t exist, using U.S. In the United States, for some unknown reason, every neon tube with a diameter larger than 15mm is called "cold cathode," and "neon" when smaller. In two articles, I will describe the method, requirements and pitfalls for a neon shop that wants to enter the larger tube business. ![]() Cold cathode - which is nothing more than neon tubing in a larger size - can be processed in the neon shop after some considerations and training. Architects increasingly use this light source due to its custom-tailored properties. Logisys 0 0 5.The principle of cold-cathode lighting is not new. Order an additional cathode tube below to be used with this dual inverter. Just plug the Cathode in, mount the tube using the zip ties and the square mount, flip the switch, and you're set!Īll Cathode wiring comes with a professional single braid sleeved harness in your choice of Premium Allure High Density colored sleeving and heatshrink for that neat and clean look!

This kit provides the ease of use and the brightness that any modder has in mind. Light Output and energy consumption chart of Cold Cathode Lamps. Logisys Kits now are now 50% brighter: Brightness: 29,000 cd/m2!!! Cold Cathode's provide many benefits and features over standard neon's: Longer life expectancy, Brighter, Consumes less power, etc. The largest commonly available colored CCFL is 20', and those generally run about 15-20 per CCFL, and require their own special inverter. CCFLs come in various sizes, ranging from 4' -> 36'. We also have more than 200,000 complete LCD backlight assemblies in stock in addition to the millions of CCFL backlights Plazmo has in stock. Cold Cathode Fluorescent Lights (6 per 2x 12' Tube Kit) You have many options here. Cold cathodes are the most common method chosen by any case modder to brighten up his/her case.
