Is 5W equivalent to 40w?
A high quality, dimmable LED filament lamp with pearl glass finish.
How much power does a 40 watt LED use?
A 40 Watts bulb is capable of drawing 0.36 Amps to operate.
What does 5W mean in light bulb?
The simplest way to measure the efficiency of an LED light bulb is to calculate its lumens to watt ratio. To do this, just divide the number of lumens it emits by its wattage: for example, a 5W bulb that emits 400 lumens has a ratio of 80 lumens per watt (abbreviated to lm/w).
How many watts does a 40 watt LED bulb use?
5 watts
Compare wattage

| 75 watts | 45 watts | 9 watts |
| 100 watts | 60 watts | 12 watts |
How much current does a 5W LED bulb use?
5 watt led bulb power consumption per hour: Yearly power consumption = 5*24*365 + 10\% power loss = 43800 + 4380 = 48180 Watts hour. Converting into units 48.18 units per year is the yearly consumption of 5 watts LED bulbs.
WHAT LED bulb replaces a 40 watt bulb?
General Electric, the granddaddy of light bulbs, has developed an LED replacement for 40-watt bulbs that can last for 17 years. GE on Thursday unveiled the Energy Smart LED bulb that puts out 450 lumens–about the same output as a 40-watt incandescent–while consuming 9 watts.
Do LED lights use a lot of electricity?
In general, LED Lights use less electricity and last longer than incandescent or CFL bulbs. LED lights also use very little electricity in comparison to traditional incandescent bulbs.
How bright is a 40 watt LED bulb?
A standard 40W bulb is equal to 400+ lumens, which represents the brightness of a bulb.
Do LEDs draw less current?
LEDs draw less current (fewer amps) than incandescent and fluorescent lights of the same brightness. They draw much less current than incandescent bulbs of an equivalent visible light output, and somewhat less than fluorescents.
What is the actual wattage of a 40 watt bulb?
That 40 watt is the actual wattage that the socket can handle. You can use an LED bulb with an actual wattage of 40 watts. You will get lots of light from such a bulb.
How does the wattage of an LED light bulb work?
When a lamp lists a maximum wattage, its doing that based on the heat an incandescent bulb of that wattage will put off. The 9W=75W on the LED bulb is telling you that “even though this bulb only uses 9W of power, it puts out the same amount of light as a 75W incandescent”. Lamps are rated on heat and power usage not light output.
What does 9W=75W mean on a light bulb?
@Jim: That’s not really right. The meaning of 9W=75Wis that the LED lightbulb consumes only 9W of electric power to produce the same light output (luminous flux) as would be produced by a 75W tungsten-filament incandescent lightbulb. I find it best to use lumens to compare lightbulb brightness.
What does 40W mean on a light socket?
It’s the electrical wattage you must not exceed. The 40 watt rating of the socket only refers to an incandescent bulb. Engineers describe an incandescent bulb as a heater with light as its waste output. A larger incandescent heater would damage the fixture from heat.
