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.
From halogen to LED you can divide by 4 to find the equivalent. Therefore an 80 watt LED would do the job.
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.
A 5050 LED typically produces around 16 to 20 lumens per chip, depending on the specific model and manufacturer. Since a 5050 LED contains three chips in one package, the total output can range from approximately 48 to 60 lumens per LED. However, the actual lumen output can vary based on the color temperature and efficiency of the LED.
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 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.
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.
1800lumens per watt
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.
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.
From halogen to LED you can divide by 4 to find the equivalent. Therefore an 80 watt LED would do the job.
