How Many Lumens Are In A 25 Watt Incandescent Light Bulb

Since most household bulbs are 40w 60w 75w or 100w you may be able to memorize their equivalent lumens.

How many lumens are in a 25 watt incandescent light bulb.

40w equals 450 lumens 60w equals 800 lumens 75w equals 1100 lumens and 100w equals 1600 lumens. If you want something dimmer go for less lumens. Replace a 60w bulb with an energy saving bulb that gives you about. Are you looking for an energy efficient replacement for your 25 watt light.

Some of the most energy to light efficient led bulbs are now reaching over 120 lumens in energy star tests. Watts to lumens calculator lumens to watts calculation formula. Replace a 75w bulb with an energy saving bulb that gives you about 1100 lumens. In the table below you can easily see how much 25 watt in lumens is and which alternatives you can choose.

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. Rely on new bulb labeling standards to show lumen output and help you choose the right brightness for your needs. P w φ v lm η lm w lumens to watts table. Energy saving lamps have high luminous efficacy more lumens per watt.

As a rule you ll replace a standard 75 watt bulb with an energy saving bulb of about 1100 lumens. The power p in watts w is equal to the luminous flux φ v in lumens lm divided by the luminous efficacy η in lumens per watt lm w. On the low end replace a 40 watt bulb with an energy saving bulb of about 450 lumens. If you prefer brighter light look for more lumens.

Some of the common wattages vs. To replace a 100 watt w incandescent bulb look for a bulb that gives you about 1600 lumens. Wattage to brightness comparison.
