Okay so I searched for 3 hours on Google and no answer so here it is: 40W - 110C; 60W 140C; 100W 136C; and 100W Flood (Red Green Yellow) 125C. Standard bulb, 117VAC, 60Hz, facing up (edison Base down, free air, 22C ambient, measured with K-type thermocouple, calibrated in last 12 months....

∙ 15y agoFor a common light bulb, the average person usually can guess by the wattage of the bulb how powerful it will be (more watts means will mean more heat/light). Properly speaking, the "candela" (sometimes called a "candle") is the unit of "luminous intensity" which is often used scientifically to gauge how much light an object generates. Appropriately enough, the average candle emits approximately one candela of luminous energy.

http://www.akatoo.com/question.html?question_id=55474 Watts = Amps x Volts, Amps = Volts/Resistance. Measure the resistance of the bulb and divide it into the voltage the bulb uses. This will give you the amps drawn by the bulb. Now multiply the amps by the volts and it will give you the watts the bulb draws. eg. a 120 volt bulb has 144 ohms resistance, Amps = 120/144 = .833 amps. .833 amps x 120 volts = 99.96 or a 100 watt bulb.

Why is a light bulb called a light bulb?
A light bulb lights up when electricity is applied, and it has a bulbous shape. Q. How do people know how a bulb looks in the past years it has changed and and it has diffrent shapes. A. The same way that they know that a phone dial was called a 'dial' because it was a circular like the face of a watch. Oh, right.
Why has the incandescent light bulb become obsolete?
know one cares
How many watts does a 60w light bulb consume in a day - in pound sterling?
A 60 Watt light bulb consumes electrical energy. If you leave is on for 24 hours, it consumes 60 x 24 = 1440 Watt-Hours, or 1.44 Kilowatt-Hours. If you want to know how much money this much energy costs, look on your last electricity bill. There it will give the cost of one Kilowatt-Hour.
How do you know whether to get 120 volt or 130 volt light bulb?
If you want your bulbs to last longer then use 130 volt bulb on a 120 volt system. The light emitted by a 130 volt bulb, when comparing it to a 120 volt bulb, will be a bit dimmer.
Was the light bulb invented in accident or in purpose?
The incandescent light bulb as we know it was invented by Thomas Edison. It was invented deliberately and after much trial and error by a very large number of people.
What do you need to know to calculate how much energy light bulb uses?
You should be able to read the power off the bulb or its packaging.
How do you know a light bulb transforms 100 percent of its electricity into light?
You don't. A light bulb transforms only a fraction of its energy into light, and most of it into heat. For an incandescent bulb about 3% is transformed into light, while for a compact fluorescent (low-energy light) about 15% is transformed into light.
How are modern light bulbs different from the old light bulb?
I think they save energy and are folersent but what do i know
3 examples of energy transformations?
Want to know what to examples of energy transformation. They are , turning on a light bulb and solar panels.
How do you know how to change the front light bulb on a 2002 Malibu car?
Remove the light bulb connector from the light. Take hold of the light bulb, push in and turn at the same time. The light bulb will come out. Reverse the process to install the new light bulb.
Is electric energy converted to heat energy or light energy?
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
What are the energy transformations that occur in a candle?
In a light bulb, electrical energy is transformed into light energy and heat energy.
What is most energy efficient led lamps or bulbs?
The most efficient outdoor light bulb would the 5 watt Light emitting Diode light bulb also know as the LED bulb. They are small lights with miniature sockets or made to fit into conventional sockets.
How do you invent the light bulb?
Lol you cant invent the light bulb .It was already invented . Did you know that Thomas eddison did not invent the first eletirc light bulb but the first incandesent light bulb . It took him alought of research and work to invent ithe light bulb though .
How do you calculate the frequency of light emitted in chemicals?
There are several ways to calculate the frequency of light emitted or absorbed by different chemicals, and they depend on what you already know. For example, if you know the energy of the particle, then you can calculate frequency from E = planck's constant x frequency and solve for frequency. If you happen to know the wavelength, then you can use C = wavelength x frequency and solve for frequency (where C = speed of light).
How do you know that house lights are wired?
When you turn the light switch to the up (on) position, if the bulb is not burned out, the light bulb will glow.
What did the light bulb say to the other light bulb after he failed the test?
You know..you're really not that bright. - Elizabeth Leffingwell
