Lumens measures how bright it is, watts measures how much electric power it uses up.
An old-type incandescent bulb produces about 10 lumens per watt.
A halogen produce about 13 lumens per watt.
A fluorescent (energy saving) bulb produces about 50 lumens per watt.
LEDs produce somewhere around the same as a fluorescent.

What is the LED equivalent of a 35 Watt halogen bulb?
Incandescents produce 10 lumens per watt, halogens about 13 lumens per watt, fluorescents and LEDs 40-50 lumens per watt. Lumens measure the brightness, watts measure the speed at which electrical energy is used.
How many amps in a 40 watt light bulb?
A lumen is the perceived intensity of the light, as seen by the human eye. The lumen value is largely determined by the the nature of the light, i.e. the sum of the different wavelengths of the light being transmitted by the particular bulb type.The standard tungsten wire-filament ('incandescent') bulb radiates a different type of light to a flourescentlight.* a 230 V, 40 watt incandescent bulb produces a light (quality) of about 400-500 lumens,* a standard 230 V flourescent lamp of only 7 watts will produce exactly the same value of lumens, i.e. 400-500 lumens. * the cool white XLamp XP-G 3.5 V LED lamp of only 3 watts will produce a similar value of lumens, i.e. 350 lumens. And is safer for the workers that make them and better for the environment. It is currently more expensive, but prices have been dropping about 20% per year. Therefore LED light bulbs convert electricity into light more efficiently than incandescent or florescent light bulbs. * For more information, See Related links below this box
How many watts does a portable fan use?
The average household fan used in US or Canada is about 35-50 watts.
How many watts does a average printer use?
A typical ink-jet printer such as used at home would draw around 5 watts on stand-by and 25 to 35 watts while printing. A typical laser-printer such as used in an office would draw about 35 to 50 watts on stand-by and up to about 350 to 500 watts while printing.
How many watts does it take to power a normal hair straightener?
35 watts. Mabye, but you have to add that all are of different wattage.
How many watts equal 35 lumen's?
There is no direct conversion for this, because these are two separate things. Watts is actual power usage. "Lumens" is how much light is provided from a specified amount of power. The typical light bulb converts some of the electricity driven through it into light, and the rest into heat. The more efficient the light bulb, the less power per lumen will be required.That is why newer bulbs can be purchased that are 13 watts and advertised as equivalent to 60 watt incandescent bulbs - the light output is roughly equivalent (lumens), but the power usage is substantially different.
What is the LED equivalent of a 35 Watt halogen bulb?
Incandescents produce 10 lumens per watt, halogens about 13 lumens per watt, fluorescents and LEDs 40-50 lumens per watt. Lumens measure the brightness, watts measure the speed at which electrical energy is used.
How many lumen's are in a 36 watt T8 fluorescent tube?
2300lm Comment I think you mean lumens, not lumen's. No that answer is wrong Watts (energy usage) / Lumens (light output) 25 is equal to 200 35 is equal to 325 40 is equal to 450 60 is equal to 800 75 is equal to 1100 100 is equal to 1600 125 is equal to 2000 150 is equal to 2600 36 watts would be about 350 Lumens
What type of bulb uses the Mercedes Benz C300 low beam?
h7 bulb type. 35 watts. 55 watts is ok too but becareful with the lighting harness.

What does the efficiency of a machine describe?
The efficiency of a machine is: (useful energy that comes out of the machine) divided by (energy put into the machine). It's really handy to know this before you spend a million dollars on a machine, and discover that even though you put enough energy into it to do the job, you're not getting enough out, and the job isn't getting done. Example: You need 100 watts of light dispersed in a room. You buy a 100-watt light bulb, screw it in, turn it on, and nobody in the room can read anything. You lose, because you failed to consider that the efficiency of the type of light bulb you bought is about 35%. That means for every 100 watts of electricity you put into the bulb, you get about 35 watts of light out of it. The other 65 watts of power comes out of the bulb in the form of heat. (Which explains why the air conditioning runs more when the lights are on.) Had you considered the 35% efficiency of the light bulb, and knowing that you needed 100 watts of light, you would have known to buy a bulb rated at (100 / 0.35) = 286 watts.
How many watts does a hair straightener?

How many watts are the front and rear premium speakers in a mercury topaz 1989?
25 to 35 watts
How dou you convert joules to watts?
Joule is a unit of energy, watt is a unit of power. Power is energy per time unit. In a way, those are incompatible units, but if you know in what time you spend a certain amount of Joule, you can convert to Watt, and vice versa. For example, if you use 200 Joule in 2 seconds, that is 200/2 = 100 Joule/second, or 100 Watts. Or, if a light-bulb uses 35 Watts, that is 35 Joules every second, so in an hour it will use 35 x 3600 = 126000 Joules, or 126 KJ.
