To help consumers buy cfls and led bulbs the federal trade commission and manufacturers have worked.
100w bulb lumen output.
In the table below you can easily see how much 100 watt in lumens is and which alternatives you can choose.
Replace a 75w bulb with an energy saving bulb that gives you about 1100 lumens.
881 885 889 893 894 896 898 9004 9005 9005 9006 9008 h1 h3 h4 h7 h10 h11 h12.
With energy efficient lighting like leds and cfls how many lumens are in a 60w bulb or 100w bulb depends on the lumen output of the bulb not its energy use.
On the low end replace a 40 watt bulb with an energy saving bulb of about 450 lumens.
To replace a 100 watt w incandescent bulb look for a bulb that gives you about 1600 lumens.
Energy saving bulbs such as compact fluorescent lamps and led bulbs that produce an equivalent lumens as the 100 watt incandescent bulb use only 24 to 25 watts of energy.
A metal halide mh lamp is an electrical lamp or bulb that produces light by creating an electric arc combining a gaseous mixture of vaporized mercury and various metal compounds bromine or iodine.
To make sure we get the correct replacement bulb in terms of the brightness we need to think in terms of light output.
If you want something dimmer go for less lumens.
Manufacturers are also changing the look of their overall packaging to help even more.
In old incandescent technology there was a clear link between the light output of a bulb and the amount of power it used.
Lumens is an accurate way of measuring the light output of bulbs brightness is what we perceive luminance is what we measure.
A 100w bulb was brighter than a 40w bulb but this isn t always the case anymore.
For instance the cfl in the photo on the right says the sylvania super saver cfl is a replacement for a 100 watt bulb with a lumen brightness output of 1500.
For example to replace a 100 watt light bulb for a led lamp the amount of lumens must be compared.
These bulbs also last longer allowing users to save more on energy costs.
A type of high intensity discharge hid lamp this light is typically used in high bay lighting fixtures in warehouses parking lots and hangars because of their high lumen output.
Replace a 60w bulb with an energy saving bulb that gives you about.
Because lumens measure brightness and watts measure energy output there is no simple method for converting wattage to lumens.
As a rule you ll replace a standard 75 watt bulb with an energy saving bulb of about 1100 lumens.
Rely on new bulb labeling standards to show lumen output and help you choose the right brightness for your needs.
However this can be a little confusing.
