Do the same wattage candelabra and incandescent bulbs draw the same power?

Yes, wattage is wattage, is wattage, is wattage. "Power" is calculated in wattage. It equals the voltage times the current in amps. In a light bulb, the resistive filament will cause a certain amount if current to flow making the filament hot and producing light.

Can you use 40 watt in a fluorescent light in place of a 32?
Yes, the wattage is just the power consumption. A 30 watt Fluorescent will give more or less the same light as a incandescent bulb or 60 watts, which is the limit for your fixture for incandescent bulbs.
Why can light bulbs be called heat bulbs?
Heat bulbs would be a more appropriate name because incandescent bulbs transform 90% of electricity received into heat and 10% into light. New Compact Fluorescent light bulbs use only 20% to 30% of the energy needed to power a standard bulb for the same wattage.
Electrical power in light bulbs is measured in what?
wattage or watts
Can I put a UV bulb to power a lava lamp?
The dark black incandescent type UV bulbs will work as they actually get hotter than the equivalent standard incandescent bulb of the same wattage, but the compact fluorescent type UV bulbs run too cool.
How are light bulbs measured?
Brightness of a light bulb depends on the power, current, resistance and size of the filament. Lumens is the unit of measurement for the brightness of a bulb. A bulb has more brightness if there is more power and current. Greater the resistance, less is the brightness.
Why should people change away from using incandescent light bulbs?
Incandescent light bulbs not only produce more heat, but use far more power than LEDs, and last a much shorter lifetime.----------------------------------------------------------------------------------------------------------------------------------------------Except for low wattage incandescents they are no longer being manufactured, so when current stocks run out you will haveto change to either CFL or LED lightbulbs.
Do dimmer switches save energy?
no i think the same amount of power is needed to push through the variable resistor in the dimmer switch coil.
What is the power of a light bulb?
Every person has a different power of light bulb. In my room, I have a 7.5 and a whole bunch of 60s. The number of watts you choose for your light bulb depends on how bright you want your light to be. The higher the number, the brighter it is.
What is the maximum voltage of incandescent light bulbs?
The maximum voltage of incandescent light bulbs is up to about three hundred volts. They can also go down as low as 1.5 volts. Incandescent light bulbs are the least efficient lighting system. More modern methods like flourescent lightbulbs are far more efficient.
What is the difference between incandescent bulbs and fluorescent bulbs Why change?
Fluorescent bulbs use less energy to produce a similar amount of light as incandescent bulbs. So they save money on power when used. But they cost more to make, and how the power consumed to make them compares I do not know. And they contain a significant amount of mercury, making them difficult to dispose of properly. There is much debate over which is better.
Two light bulbs are in series how much power is dissipated by each bulb?
this is not an easy question. Assuming these are incandescent lamps with tungsten filaments, we need to know the type and rating of the lamps (bulbs) and the voltage. Incandescent lamps are highly non-linear and vary greatly in resistance depending on temperature--at lower voltage, the temperature is lower and the resistance is less. The problem is finding the stable operating point at the lower voltage. Probably the easiest way to answer this is build the circuit and measure. As a general rule, if the two in series bulbs are equal wattage, each one will dissipate 1/3 of its rated wattage (at half voltage). So two 25W bulbs in series will each dissipate about 8W, or 16W total.
How does the lumen output change as wattage increases for an MR16 bulb?
Generally the lumen output of bulbs is proportional to the power used, if the bulbs are operated at their rated voltage.
