it depends, lumens measures light and watts measure power. check out this article; http://wiki.renderplus.com/?title=Lumens_vs_Watts
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.
The conversion from lumens to watts isn't direct, as lumens measure light output while watts measure energy consumption. The efficiency of the light source affects the conversion; for example, an LED bulb typically produces about 80-100 lumens per watt. Therefore, 190 lumens would require approximately 2-2.4 watts if using an LED bulb, but this can vary with different types of bulbs.
The conversion from lumens to watts isn't direct, as it depends on the efficiency of the light source. For example, LED lights typically produce about 80-100 lumens per watt, while incandescent bulbs produce around 10-17 lumens per watt. Therefore, for LED lighting, 10,000 lumens would require approximately 100-125 watts, while for incandescent bulbs, it could require 600-1,000 watts.
A 12V 2.5Ah battery can power a 3W LED for approximately 10 hours. This calculation is based on the formula: Battery life (in hours) = Battery capacity (in Ah) / Load power (in A). In this case, 2.5Ah / (3W / 12V) = 10 hours.
From halogen to LED you can divide by 4 to find the equivalent. Therefore an 80 watt LED would do the job.
The maximum lumens that a 1-watt LED flashlight can have now is 160.
About 80 lumens per watt of electric power is normal for LEDs.
A good projector will have 2000 or more lumens, but an LED projector will have much less.

Currently maximum LED luminous efficiency is about 114 lumens/W, measured at 50mA. Average luminous efficiency is about 104 lumens/W. Ordinary LED light effect is about 60 lumens / W. 18W is about 130 lumens is about 1080 lumens.
1800lumens per watt
A 3W LED bulb is equivalent in brightness to a 25W traditional incandescent bulb.

161 lumens I believe the above answer to be inaccurate. It depends on the light source. For example: For an incandescent light bulb 1 watt it is approx. 18 Lumens. However most LED's use only about 10% the wattage to produce the same amount of light. So for LED's .1 watt produces 18 Lumens.
