400 Watt Bulb Lumens

Energy saving lamps have high luminous efficacy more lumens per watt.

400 watt bulb lumens. On the low end replace a 40 watt bulb with an energy saving bulb of about 450 lumens. Because lumens measure brightness and watts measure energy output there is no simple method for converting wattage to lumens. The luminous flux φ v in lumens lm is equal to the power p in watts w times the luminous efficacy η in lumens per watt lm w. 150 watt e39 led bulb 21 892 lumens 5000k replacement for 400 500 watt metal halide hid hps or cfl high efficiency 125 lumen watt 360 degree lighting led corn light bulb 4 7 out of 5 stars 188.

For example to replace a 40 watt light bulb for a led lamp the amount of lumens must be compared. 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. Converting lumens to watts.

As a rule you ll replace a standard 75 watt bulb with an energy saving bulb of about 1100 lumens. In the table below you can easily see how much 40 watt in lumens is and which alternatives you can choose. Lumens to watts calculator watts to lumens calculation. P w φ v lm η lm w lumens to watts table.

A new metal halide bulb can get almost 100 lumens to watt. What is hard to cross in is that metal halides actually start out at very high efficiencies. 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.
