What percentage is a 100 watt light bulb brighter than a 60 watt light bulb?
Original answer: Because it gives off more power. Updated answer: In general, because the 100-watt bulb produces more total light (lumens) because it also consumes more power than the 60-watt bulb. However, a 60-watt can produce more lumens than a 100-watt bulb, depending on the types of bulbs in question.
Which glows more brighter a 100 w bulb or a 75 w bulb explain?
A 100 watt bulb will normally glow brighter than a 50 watt bulb as long as you are comparing similar style bulbs. You have to compare Incandescents to Incandescents, Fluorescent to Fluorescent, LED to LED, and so forth. You also have to make sure your bulbs are similar in light patterns since you can have general dispersion lighting, spot lighting, flood lighting, and so forth. So, once again as long as you are comparing like style bulbs, yes a 100 watt bulb is brighter than a 50 watt bulb.

Why are stars brighter than the sun?
Most stars are dim red dwarfs which we cannot see. Most of the stars we can see actually ARE brighter than our sun. From our perspective, because we are so close to it, the sun appears big, the same reason a 100 watt light bulb in the same room appears brighter than stadium lights four miles away.
Which bulb uses more electricity40 watts100 watts or 120 watt?
The higher the wattage the more you pay for power. So it costs more to operate a 120 watt bulb than it does a 100 or 40 watt bulb.
How much energy does a nightlight use compared to a 100 watt bulb?
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.
What type of light is a 20 watt energy saving bulb Halogen Incandescent neon or fluorescent?
A 20 watt incandesent bulb is dim. For a medium sized room you need 100 watts. A 20 watt halogen bulb is brighter but still quite dim. These are marketed as low-energy but they are not. For a medium sized room you need 80 watts. A 20 watt fluorescent bulb can light a medium sized room quite brightly. This is a genuine low energy bulb.
