The bulb will have an efficacy of 17-20Lm per watt, so in total 500W = 8,500-10000 lumens. However, the bulbs light output is non directional, so a lot of the spilled light is in directions that you don't want it to go, so 50-70% of the figure can be used when specing up an LED variant.

40 watt light bulb. This is obvious. Go do an experiment. -_-

MW is a unit of power just like kW 1MW = 1000 kW 1 mega-watt = 1000 kilo-watt Watt is a measurement of power. watt-hour is a unit of energy 1 mega-watt-hour = 1000 kilo-watt-hour

The voltage isn't decided by the lamp, but by the supply the lamp is hooked up to.

If you can use it in your lamp it will be a 20 watt bulb

Incandescents produce about 10 lumens per watt.

A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.

This depends on the type of bulb and it's efficiency. Incandescent bulbs produce 700-900 lumens at 60 watts.

around 21,000 average 100 watt bulb is around 1400 lumens. That's 14 lumens per watt. 14X1,500 = 21,000

How many lumens are in a 100 Watt Metal Halide bulb

Ordinary incandescent bulbs produce 13 lumens per watt. For halogen bulbs, 17 lumens per watt; for CFLs 65 lumens per watt; for LEDs up to 100 lumens per watt have been claimed

Approximately 15 lumens per watt for halogen, so 300 lumens.

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.

A guide figure for an incandescent bulb is 10-12 lumens per watt for ordinary incandescent, 15 lumens per watt for halogen type.

NO 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.

Normally the watts is a measure of how many watts of electicity a bulb uses, so a 60 watt bulb uses 60 watts. The brightness is measured in lumens, so a 60-watt incandescent blub might produce 600 lumens while a high-efficiency fluorescent blub might produce 3000 lumens.

2600-2800 lumens
