There is no direct conversion between lumens and watts for LEDs since they are measured differently. However, as a rough estimate, a 60-watt incandescent bulb produces about 800 lumens. For an equivalent LED output, you would typically need an LED bulb with around 800 lumens.

There is no direct conversion between lumens and watts as they measure different things. Lumens measure the total amount of visible light emitted by a source, while watts measure the amount of energy consumed or produced. The equivalence between lumens and watts depends on the type of light source (i.e., incandescent, LED, etc.) and their efficiency.
The number of watts needed to produce 820 lumens depends on the type of light source. For traditional incandescent bulbs, it would be around 60-70 watts. However, for LED or CFL bulbs, it would be much lower, around 10-15 watts.
To convert lumens to watts, you need to consider the efficacy of the light source, as different types of bulbs produce different amounts of light per watt. For example, an LED bulb typically produces about 80-100 lumens per watt, while an incandescent bulb produces around 10-17 lumens per watt. Therefore, 1.2 lumens would be approximately 0.012 to 0.12 watts for an LED, and around 0.07 to 0.12 watts for an incandescent bulb. The exact wattage can vary based on the type of light source.
If you have the wattage of the laser you can plug it into a formula X/P=L. Where One lumen is equal to 0.001496 watts (1.496mW) which is Power. X is the number of watts or milliwatt and L is Lumens. So if you have a 1 watt laser you have 668.449 lumens being produced by it.
Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.

220 lumens is equal to a tungsten incandescent light bulb of 15 watts. Halogen lamp 20 watts. Fluorescent lamp 60 watts. LED lamp 60 watts. high pressure sodium vapour lamp 117 watts. Mercury vapour lamp 50 watts or 17.32 candle power
The conversion rate from 150 watts to lumens depends on the type of light source being used. For incandescent bulbs, a rough estimate is around 1500 lumens. LED bulbs may vary, but generally, 150 watts would be equivalent to around 3000-4000 lumens. It is recommended to check the specific specifications of the light source for an accurate conversion.

The main types are: Incandescent 10 lumens per watt Halogen 13 lumens per watt Fluorescent 40-50 lumens per watt LED 40-60 lumens per watt Lumens measures the brightness, watts measures the electric power used.

The maximum lumens that a 1-watt LED flashlight can have now is 160.
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.
Brightness is measured in lumens so the bulb has a brightness of 100 lumens. The electrical power the bulb uses is measured in watts. The efficiency of a bulb is expressed in the number of lumens produced per watt of electric power.
