According to Energy Star, a standard 100-watt incandescent light bulb emits 1,600 lumens of visible light. With that said, the answers are misleading depending on which fluorescent bulb or fixture manufacture you’re talking too. But many of us do have some idea of how bright a 100-watt bulb is. Also, we’ve included the different types of light bulbs, so you can … The WATTS is a measure of the amount of energy used by bulbs and the LUMENS is the measure of brightness provided by a light bulb (the higher the lumens the brighter the bulb). On average, an incandescent bulb produces around 14 lumens per watt, compared to 63 lumens for energy saving compact fluorescents (CFL) and 74 for LED bulbs. Watts. Try this for a start. A lumen measures the amount of light that comes from a bulb. "14-17.5 lumens per watt for standard "A19" 120 volt 60 to 100 watt incandescents, and typically 16 to 21 for most halogen lamps." So, when buying book light, or reading lamps for reading at night, you do not need to look at the watts. The luminous efficacy of an incandescent light bulb is set at 16 lumens per 1 watt. You will no longer be able to find or buy 100 watt bulbs. Common terms are ‘soft white 60,’ ‘warm light 60,’ and ’60 watt replacement.’ To save energy, find the bulbs with the light output you need, and then choose the one with the lowest wattage. So if a 100-watt incandescent produces 1,500 lumens, and a 10-watt LED does the same, the 10-Watt LED may advertise “100-watt equivalent” on its label. A source radiating a power of one watt of light in the color for which the eye is most efficient (a wavelength of 555 nm, in the green region of the optical spectrum) has luminous flux of 683 lumens. While that works for incandescent bulbs (although, even then, it is an imprecise way of measuring brightness), with the development of low-energy LED light bulbs, the wattage alone will not necessarily indicate how bright a bulb is. Lumens. They will vary from manufacturer to manufacturer. We all know how much light a 60-watt bulb will produce. Lumens actually measure light output. Lumens is a unit of measurement for brightness. So, the question is how many lumens do a 1000 watt MH lamp produce in compared to LED?
