Electricity is the force that energizes all that we do. One concept that must be understood is power. All lamps are rated in watts, a measure of power. We will begin by defining a few terms related to electricity. The four terms we need to understand are Voltage, Amperage, Resistance, and Wattage. We will use a water model to help define and understand these terms. If we look at a water pipe as an example of an electrical wire, and in the example, the water pipe is hooked up to a water wheel, then we could call the friction that the wheel has while turning "the resistance". All light bulbs present a certain resistance to the flow of electricity. If we turn on or open a faucet, water starts to flow. This flow is just like bringing the level up on a dimmer. The pressure of the water in the pipe is directly comparable to the voltage in an electrical circuit. As you bring up a dimmer you are increasing the voltage. In our water model we could say we have increased the water from a trickle to a torrent. The next term to consider is amperage. The size of the pipe carrying the water is the corollary for amperage. The larger the diameter of a pipe, the more water can flow. The larger the gauge, or diameter of a wire, the more current can flow. Fuses and circuit breakers are rated in amperage. They provide protection in an electrical circuit. When you try to draw more amperage through the circuit than the fuse or circuit breaker is rated for, the fuse or circuit breaker will "blow". The larger the fuse or circuit breaker, the more lighting fixtures you could use. In our water model we could measure the amount of water flowing past the wheel as it "spins" the wheel. The amount of water flowing as well as the pressure and rate of flow controls the speed of the spinning wheel. In the case of our lighting instrument, we control the power with our dimmer. The measurement of the amount of power flowing past the light bulb, our spinning  wheel in the water model, is called wattage. In electrical terms we measure wattage, the amount of amperage or current flowing past a point at a certain voltage or pressure. We can define "Power" as the measurement of how much work is being done. In the case of the water model example, we would multiply the amount of water that flows by the pressure, or how much we opened the tap. If the friction or resistance is a small number and we open the tap all the way then the amount of water will be large. If the friction is large then the amount of water flowing will drop down. However, the resistance provided by the wheel is not a factor we need to be concerned about in lamps. Most of the time we are concerned with how much amperage is being used by a lamp, not how much resistance it places in the circuit. Long ago a man named Ohms figured out these relationships and set them down. We know them as Ohms Law. He set them down using the following variables in 2 basic formulas. Here are the 2 formulas that we use most. 

Wattage = W
Voltage = V
Amperage = A
Resistance = R

A = V / R
Amperage = Volts divided by Resistance

W = V * A 

Wattage = Voltage times Amperage 

Wattage: The measure of the amount of work being done.

Amperage: The availability of power (controlled by the gauge of the wire and breaker or fuse rating.)

Voltage: The pressure of flow

Resistance: The friction of the light bulb or other device.

Some people remember the second formula as the mnemonic "West Virginia". 

One of the single most important things you need to understand is load calculating. Load calculation is done to insure that you do not exceed the available power. The first step is to determine what is the configuration of available power. Talk with an electrician or maintenance staff worker about available power. There are 3 basic options, 1.) 15 amp wall outlets, 2.) Single Phase power in a breaker panel, or 3.) Three Phase power in a breaker panel. You need to know which option you have and what is the available amperage per hot leg, or you need to know the total amperage. Load calculation is not a difficult task to perform; here are two methods of calculating your needs.

1.Add up the wattages of all the fixtures that you plan to use and divide that by the voltage on a single hot wire. For example, 24 fixtures at 500 watts equals 12,000 watts. In the US the voltage is a nominal 120 volts. 12,000 watts = 120 volts x what amperage? Using the formula above, you can see the required amperage would be 100 amps to utilize all 24 fixtures at once. The next step is to divide this by the number of hot legs of power connected to your dimmers. This would be either 2 or 3, based on single phase or three phase power. In the case of single phase power you would need to have 50 amps of power available per leg. In the case of three phase power you would need 33.33 amps per leg. 

     • Halogen lamps operate at extremely high temperatures that can cause serious physical injuries and property damage. 

     • Only use Halogen lamps in Halogen-approved fixtures. Fixtures should fully contain any parts of the Halogen lamp upon the event of a lamp burst. 

     • Do not use Halogen lamps in close proximity to paper, cloth or other combustible materials that can cause a fire hazard. 

     • Lamps are very fragile. Do not drop, crush, bend, or shake them. 

     • Do not touch the Halogen bulb surface or inside reflectors with your bare hands. Oils from skin can lead to breakage or shorten the life of the lamp. Use clean gloves or lint free cloth for installation and removal. 

     • Clean any dirt, oil, or lint away from the lamp with alcohol and a lint free cloth or tissue. Any foreign particles or materials on the bulb surface can cause hot spots on the bulb and result in lamp failure. 

     • Never touch the lamp when it is on, or soon after it has been turned off, as it is hot and will cause serious burns. 

     • Do not look directly at the operating lamp for any period of time; this may cause serious eye injury. 

     • Always turn off the electrical power before inserting, removing, or cleaning the lamp. 

     • Affix the lamp securely in the socket. Improper installations will cause electrical arcing, overheating, and short life to lamp and socket. Replace lamp holders and sockets when necessary. 

     • Keep the temperature of the Halogen lamp seal below 350°C. 

     • Keep the temperature of the Halogen lamp wall above 250°C.

     • Keep the temperature of the Halogen lamp bulb wall below 800°C. 

     • Make sure lamps of specified wattage and voltage are only used in appropriately rated fixtures. Unspecified use will lead to short lamp life, breakage and overheating of fixture. 

     • Lamps should not be operated beyond the total rated voltage. Avoid the use of dimmers that may drive your lamp over its rated voltage. 

     • Operate the lamp only in the indicated burn position. Failure to do so will lead to overheating and short life of the lamp. 

     • Use an external fuse when required. 

     • Do not allow one lamp to directly expose another. This may lead to overheating and shortened lamp life. 

     • Metal Halide discharge lamps emit ultraviolet radiation which is harmful to eyes and skin! 

     • Metal Halide discharge lamps should only be used in enclosed fixtures with ultraviolet absorbing filter glass. Failure to do so may cause serious skin burn and eye damage. Do not use these lamps in fixtures where any unfiltered light is emitted from the fixture. Do not operate these lamps if the ultraviolet absorbing filter glass is broken or not installed. 

     • Metal Halide discharge lamps should only be operated in an enclosed fixture that safely contains all lamp parts in the event of a lamp burst or rupture. These lamps operate at a high internal pressure and at high temperatures. A lamp burst may occur causing physical injury and property damage. 

     • Lamps should never be operated beyond their rated useful life. The risk of a lamp burst increases with lamp age, temperature, improper operation, and improper handling. 

     • Never bump, drop, apply excessive stress, or scratch the lamp. This could cause the lamp to burst! Do not operate any lamps with any traces of scratches, cracks, or physical damage. 

     • Never operate a lamp above or below its rated current or voltage. This may cause the lamp to leak or burst. 

     • Always turn off the electrical power before inserting, removing, or cleaning the lamp. 

     • Clean any dirt, oil, or lint away from the lamp with alcohol and a lint free cloth or tissue. 

     • Electrical connections should be clean and in good condition. Replace lamp holders and sockets when needed. Affix the lamp securely in the socket. Improper installations will cause electrical arcing, overheating, and short life to lamp and socket. 

     • Never touch the lamp when it is on or soon after it has been turned off, as it is hot and will cause serious burns.

     • Lamps should be allowed to cool for a minimum of ten (10) minutes after the lamp is turned off. 

     • Do not use lamp in close proximity to paper, cloth or other combustible material that can cause a fire hazard. 

     • Do not look directly at the operating lamp for any period of time; this may cause serious eye injury. 

     • WARNING! Xenon arc lamps could burst when not in operation causing serious injuries! It is critical to follow safety instructions when handling Xenon arc lamps! 

     • Xenon arc lamps have a high internal pressure. Depending upon the lamp, the internal pressure can exceed 10 ATM or 147 PSI, even when not in operation. 

     • Always wear eye/face and body protection when handling Xenon arc lamps! 

     • Never bump, drop, apply excessive stress, or scratch the lamp. This could cause the lamp to burst! 

     • Always transport the lamp in the provided protective case or cover until installation! 

     • Save the protective case or cover and packaging materials (box) for lamps that have been used to their rated service life. Use the protective case when disposing of the lamps. 

     • Never touch the lamp when it is on, or soon after it has been turned off, as it is hot and will cause serious burns. Lamps should be allowed to cool for a minimum of ten (10) minutes after the lamp is turned off. 

     • Always operate the lamp in closed, protective housings. 

     • Do not look directly at the operating lamp for any length of time; this may cause serious eye injury. 

     • Do not use lamp in close proximity to paper, cloth or other combustible material that can cause a fire hazard. 

     • Some Xenon arc lamps produce Ozone that is considered toxic at relatively high concentration levels. Use ozone-producing lamps in lamp housings equipped with exhaust systems. 

     • Never operate a lamp above or below its rated current or voltage. This may cause the lamp to leak or burst. 

     • Affix the lamp in the correct polarity according to the lamp and fixture design. 

     • Affix the lamp by hand tightening only. Do not use any tools to tighten nuts or the lamp itself. Any excessive stress to the lamp will cause a burst. 

     • Electrical connections should be clean and in good condition. Replace lamp holders and sockets when needed. Fix the lamp and its lead wire firmly to the terminals. 

     • Clean any dirt, oil, or lint away from the lamp with alcohol and a lint free cloth or tissue. 

     • Xenon arc lamps should not be used beyond their rated service life. Operation beyond the rated service life will cause the lamp to burst. 

     • The lamp must be operated under the specified conditions such as lamp aperage, voltage, and cooling conditions. 

     • Do not overcool the lamp. Air should never be directly forced on the bulb because uneven cooling will result. 

     • Recommended cooling methods are: air flow, N2 gas flow, heat sink and an exhaust duct. 

     • The lamp base temperature must be kept below 200 degrees C. 

     • Wear a protective mask, leather gloves and protective clothing when handling a spent lamp. 

     • Place the used lamp in its original protective case and original cardboard packaging (box) that was provided when the lamp was new. 

     • Firmly attach tape around the original cardboard box to seal the lamp securely. 

     • From approximately three (3) feet in height, drop the cardboard box, with the lamp and protective case inside, onto a hard floor to break the lamp. 

     • Shake the cardboard box to determine that the lamp is broken. 

Facts of Light
A Light Year is a measure of distance, not of time.
Since light travels at a rate of 186,000 miles per second, a light year is about 6 trillion miles.

You can screw an E27 screw base into an E26 socket.
You cannot screw an E26 screw base into an E27 socket.
You would think that the smaller would screw into the larger but it is an issue of thread count and length.
In some cases you can bend the center contact in the lamp socket out and use the E26 in the E27 socket in base down operation.
Please turn of the electricity to the socket before adjusting the tab or you might have an exciting experience.

Mazda: On December 21, 1909, General Electric first used the name Mazda on their lamps.  The name was trademarked and assigned the number 77,779 by the United States Patent and Trademarke Office.  Today, we associate the name with automobiles, but when it was first used by GE it was chosen to represent the best that the American Lighting industry had to offer at the time, and it was selected due to the fact that Persian mythology gave the name Ahura Mazda to the god of light. General Electric dropped the Mazda trademark in 1945, and ceased licensing the name as well.
