What does watt mean on light bulb? Watts measure the amount of electricity used and Lumens determine the ‘brightness’ of a bulb. The ideal combination being: LOW WATTAGE + HIGH LUMEN = BRIGHT ENERGY EFFICIENT LIGHT BULB.
Is 40W brighter than 60w?
Here is a breakdown of traditional watt light bulbs and the amount of light they produce in lumens: 40-watt bulb produces 450 lumens of light . 60-watt bulb produces 800 lumens of light (most widely used in households) 75-watt bulb produces 1,100 lumens of light.
Does wattage matter for light bulbs?
When it comes to how much light you get from a light bulb, watts don’t matter . Light isn’t measured in watts. It’s measured in foot-candles or lumens. One foot-candle, as the name implies, is the equivalent of the light from one candle, measured at a distance of 1 foot from the center of the flame.
Does more watts mean brighter light?
The higher the wattage, the brighter the light , but also the more power it uses. The efficiency of this system was introduced using incandescent lamps. For instance: 40 Watt incandescent lamp produces only 380-460 lumens and uses 40 Watts of energy per hour.
How many watts is a good bulb?
Key takeaways about powering a light bulb
On average, incandescent light bulbs use about 60 watts of electricity, and LED light bulbs use about 10 watts. Using an incandescent light bulb for 2 hours per day will use about 12.2 kilowatt-hours of electricity per month and 43.8 kilowatt-hours of electricity per year.
What happens if I put a 60w bulb in a 40w lamp?
Using a light bulb with too high of wattage can lead to overheating of the light bulb . This heat can melt the light socket as well as the insulation of the wires. Once that happens, you put yourself at risk of arc faults, and this is something that could even lead to property fires.
How do I know what watt light bulb to use?

Which light bulb is the brightest?
When compared to other types of lighting product, LED lights are the most energy efficient and offer a brighter light for the same wattage. Good quality LED fixtures now output around 170 lumens per watt; a fluorescent puts out around 110. However, that’s just part of the story!
What happens if you use too high wattage light bulb?
If a fixture is rated for a maximum of 60 watts, then it’s dangerous to exceed that. A 100-watt bulb will draw more power through the wires than they safely can handle . (It is okay, however, to put a bulb with lower wattage in that fixture—drawing less than the wire’s maximum load isn’t a problem.)
What happens if you put a 100W bulb in a 40w lamp?
A 40-watt-rated fixture can take only a 40-watt bulb. Any more and you will incur heat damage . That heat damage may be on the ceiling itself, the light fixture’s wiring or the house wiring in the ceiling. And, of course, the worst manifestation is a fire.
What happens when you put a 100-watt bulb in a 60 watt lamp?
Putting a 100-watt bulb in a 60-watt fixture could cause intense heat, melting the light socket and the insulation on the fixture’s wires . Any time you have that kind of damage on wires, you’re at a big risk for arc faults, where an electrical current falls off its intended path— a leading cause of home fires.
Can I use a 40 watt bulb in a 25 watt lamp?
Yes, that’s fine . The ‘maximum wattage’ rating listed on a light fixture is actual watts, not incandescent-equivalent-watts.
What is the most common wattage of a light bulb?
The most common types of light bulb used in homes are 25, 40, 60, 75 and 100 watts . For most rooms, a 60 watt bulb is the standard. A 25 watt bulb gives off low levels of light, where as a 100 watt bulb is very bright.
