The words "light bulb" have typically been used to describe Thomas Edison's 100 year old invention the incandescent light bulb. However the term light bulb is used in conjunction with many light sources now a days. The incandescent light bulb is an electric light that produces light when a wire filament is heated to a high temperature by an electric current passing through it. The wire terminals embedded in the glass are attached to the base of the lamp. When the light bulb base is screwed into a socket that is energized current passes through the base and into the attached terminals which are heated and light is emitted. The hot filament is protected by a glass shroud. The light bulb is filled with inert gasses to extend lamp life. In halogen light bulbs, filament evaporation is prevented by a chemical process that redeposits metal vapor onto the filament, extending the lamps life.
Incandescent light bulbs are much less efficient than most other types of lighting; incandescent light bulbs convert less than 5% of the energy they use into visible light (with the remaining energy being converted into heat). The luminous efficacy of a typical incandescent light bulb is 16 lumens per watt, compared to the 60 lm/W of a CFL (compact fluorescent lamp) and upto 100 lm/W for LED light bulbs. Incandescent light bulbs usually have short lifetimes compared with other types of lighting technologies; around 1,000 hours for standard 120V light bulbs versus typically 10,000 hours for CFL bulbs and 30,000 hours for LED bulbs.
Halogen bulbs contain a small capsule filled with Halogen gas, which emits a bright white light. Long life and full spectrum Halogen bulbs use less energy and last longer than standard incandescent bulbs of the same wattage. The life of these bulbs is around 2,000 to 10,000 hours or two to five years.
Kryton gas filled light bulbs and Xenon gas filled light bulbs are great options when compared to traditional halogen bulbs. These lamps have 3-5 times the life of regular light bulbs. They emit a much cleaner brighter white light and are more durable for your commercial applications.
LED bulbs have light emiitting diodes mounted on a chip board inside of the bulb. LEDs are a solid state technology meaning that there are no filaments. LED bulbs are extremely efficient sources of light and have a long lifetime when compared to CFL or incandescent light bulbs. LEDs are powered by a driver and as a general rule like to run on DC or direct current. Another great quality is that the LED bulbs contain no mercury so are safe for disposal.
Linear fluorescent tubes have been used since the 50's and 60's to light our offices, garages and commercial buildings. Fluorescent lamps work by sending a current through a fluorescent tube that is coated with phosphors. When the phosphors are excited the fluorescent tube will emit light. Fluorescent lamps are powered by an electronic or magentic ballast.
CFL or Compact fluorescent lamps are a very efficient form of light and consume about one quarter of the energy that a standard incandescent uses. CFL lamps are available in two types: Plug In(non integrated ballast) and Screw In(integrated ballast). CFL lamps have a typical lifetime of 10,000 hours and contain mercury so they need to be disposed of properly
High intensity discharge, or HID, bulbs include metal halide, high pressure sodium, and mercury vapor. HID lamps operate on a specific ballast and have identifiable part numbers on the glass envelope. It is very important to match up the HID lamp to the correct ANSI coded ballast.
Stage and studio lamps are typically high wattage halogen lamps that are used in conjuction with film and stagework. Furthermore these lamps fall into standard classifications to make identifying easy. These lamps conform to ANSI standards(American National Standard Institute), these lamps will have part numbers such as EKE , EXN or BTL.
Miniature light bulbs and indicator lamps are used in conjunction with lighting industrial controls and panels. These lamps come in hundreds of shapes and sizes and also follow the ANSI code system. Miniature lamps will have an identifiable part number stamped on the lamp. Common codes on lamps are 949 , 120MB & 1820.
Automotive lamps include everything from head lamps to dome lights. There are many, many types. We supply many of the common automotive halogen lights in the market.
We offer various types of replacement bulbs for DLP TVs and for LCD projectors. We offer brands like OSRAM , Philips and Ushio. Having trouble finding your bulb? Please give us a call or click the live chat button.
