Fluorescent Tubes. Different Types of Fluorescent Tubes. Lamps are typically identified by a code such as FxxTy, where F is for fluorescent, the first number (xx) indicates either the power in watts or length in inches, the T indicates that the shape of the bulb is tubular, and the last number (y) is the diameter in eighths of an inch (sometimes in millimeters, rounded-up to the nearest millimeter). filament. This is what supplies the lamp with its power. Fluorescent Tubes. Fluorescent tubes generally have a two-pin fitting at both ends of the tube and generally, length goes hand in hand with wattage – the longer the tube the higher the wattage. KOPP: "A halogen lamp works in the same way as an incandescent bulb but with one significant difference. The starter ignites the gas within the bulb and is crucial for lighting the bulb. A fluorescent tube light consists of a lime glass tube drop of mercury argon gas phosphor coating electrode coils mounting assemblies aluminum cap Total set up of a lamp requires two bases and electromagnetic ballast or choke coil with a starter. Electronic ballasts programmed start) In general, each type of ballast corresponds to a type of fluorescent lamp. Most fixtures that use T5 bulbs cannot accept T8 or T12 bulbs, and vice versa, although there are some fixtures available that can be modified to accept multiple types of fluorescent bulbs depending on the grower’s needs. When it comes to fluorescent light bulb holders and sockets, make HH Fluorescent Parts, Inc. your first stop. The bulb has two electrodes positioned right next to each other.

There are three main types of ballast: pre-heat, rapid start, and instant start. The CFL is common, of course, as is the familiar old fluorescent tube that you still see in many schools and workplaces. There are three main types of fluorescent lamps: cold cathode, hot cathode, and electroluminescent. Fluorescent bulb sockets. Fluorescent lights work by ionizing mercury vapor in a glass tube. NARRATOR: The halogen lamp, which essentially is an incandescent bulb with halogen filling, is somewhat more effective than its predecessor. Length for fluorescent tubes is generally based on the diameter of the tube, as tubes with a smaller diameter tend to be smaller in length. Other decorative light bulbs include candelabra bulbs that complement chandeliers, sconces and ceiling fans. much like the filament in an incandescent bulb. Inside the tube, it contains mercury and argon gasses which help ignite the lamp. At one time, if you had fluorescent lights in your home, it required specialized light fixtures to hold long metal fluorescent tubes (lamps) connected at the ends of the fixtures with metal pins. Fluorescent starters or glow starters are used to help fluorescent tubes and lamps ignite in the initial starting stage of their operation. Find the light bulb base type you’re looking for with this visual chart- detailed illustrations of general bases, fluorescent bases and specialty halogen base types. A number of different types of fluorescent tube have been produced since they were first introduced and patented as a commercial product in 1939. You should not regard green-tipped lamps as non-hazardous waste unless you have properly evaluated them. Bulb companies appear to be overflowing with fluorescent lights that differ in shape, size, color, brightness, fixture and longevity. These tubes vary in terms of shape, power, rating, length, colour, and other illuminating characteristics. It was in the 1940’s that fluorescent light bulbs for street lights became popular. The most common fluorescent tubes have the following diameters: The ultraviolet light makes particles that coat the inside of the tube, and these particles glow or fluoresce (see How Fluorescent Lamps Work for details)..
