If it's a long, STRAIGHT bulb...grasp with both hands - one at each end of bulb, and gently TWIST bulb toward you until it comes free of lamp. Replace by gently TWISTING new bulb back in - but in the opposite direction (counter or clock wise). If the bulb is ROUND....simply unscrew it by gently turning counter clock-wise.
40 watts. I did an experiment on this. Go do one and see for yourself. Sheesh. -_-
Well, if they're both 40 watt bulbs they use the same amount of electricity. But incandescent bulbs produce a lot of heat as well as light. Fluorescent bulbs don't produce (much) heat, so they can use their power to produce light. So you can use fluorescent bulbs of lower wattage to produce the same amount of light.So for the same amount of light, fluorescent bulbs use less electricity than incandescent bulbs.
There is no fixed relationship between the brightness (lumens / candela) of a light source, and its power consumption (watts). Incandescent bulbs have a low luminous output for their power consumption, Compact Fluorescent Lamps are intermediate, and LED's are the most efficient in today's world.
Amps ain't nothing really until you cut on a light switch in your house. It's a term of electricity measurement of which is being used in a circuit. Say you have an unlit 50 watt light bulb in your den plugged into the 110 volt outlet. The 110 volts is there ready to operate the lamp. Cut it on and the electron flow is called current. Replace the bulb with a 100 watt bulb and the current flow will double. Cut off all the lights and the power meter on your house will run slower and you use less current and will have a lower electric bill next month.
If a bulb has 50 Hz frequency and it's supply is 60 Hz frequency, it will still glow, despite the allowance of 10 HZ frequency.
10-11 lumens per watt for incandescent bulbs 13-14 lumens per watt for halogen 50-60 lumens per watt for fluorescent
This depends on the bulb design. A simple tungsten filament bulb might have a surface temperature of the bulb well above 100 C. A fluorescent lamp will be much cooler for the same light output.
The most energy-efficient option among the ones listed is the compact fluorescent light bulb (CFL). It uses about 75% less energy than incandescent bulbs, lasts longer, and produces less heat. Halogen bulbs are more efficient than incandescent ones but are less so compared to CFLs.
A 75 bulb will use more electricity.
Yes. It just won't be as bright.
Yes
No, they do not draw the same current. The current drawn by an electrical device is determined by the power (Watts) and voltage (Volts) using the formula: Current (amps) = Power (Watts) / Voltage (Volts). So, the 12 volt 50 watt bulb will draw higher current compared to the 230 volt 50 watt bulb.
No, it is not recommended to run a 50 watt halide bulb on a 100 watt halide ballast. The ballast should match the wattage of the bulb to ensure proper operation and to avoid potential damage to the bulb and ballast. It is best to use a ballast that is rated for the wattage of the bulb being used.
50 watts is 0.05 kilowatts, so in 24 hours it uses 0.05 x 24 kilowatt-hours, or 1.2 kilowatt-hours of energy.
A 100W bulb will generally glow brighter than a 75W bulb because it consumes more power and emits more light. The higher wattage means that more energy is being converted into light, leading to a brighter glow.
It depends on the specific lamp. The packaging the lamp comes in should tell you what the lumen output is. This in a common question as people want to compare LED replacements. You can use 600 lumen as a good guide for comparison for a 50 Watt halogen.
The efficiency of a device is calculated as the ratio of useful energy output to total energy input. For the filament bulb producing 100 J, if its input energy is 120 J, the efficiency will be 100/120 = 0.833 or 83.3%. For the fluorescent bulb producing 10 J, if its input energy is 30 J, the efficiency will be 10/30 = 0.333 or 33.3%. Thus, the efficiency of the filament bulb is higher.
