The maximum lumens that a 1-watt LED flashlight can have now is 160.
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.
A typical 100 watt incandescent light bulb produces around 1600 lumens. However, newer LED bulbs can produce the same amount of light using fewer watts, so the lumens can vary depending on the type of bulb used.
A flashlight typically holds and emits a range of light output depending on the brightness setting and type of bulb or LED used. Modern flashlights can have a light output ranging from a few lumens (low setting) to several thousand lumens (high setting).
A 60-watt incandescent light bulb typically produces around 800-900 lumens. However, this can vary depending on the specific type and brand of the bulb. LED and CFL bulbs can provide the same amount of light output (lumens) as a 60-watt incandescent bulb while consuming less energy.
Old style incandescent light bulbs have an efficiency of about 10-17 lumens per watt, meaning they convert only 10-17% of the energy they consume into visible light, with the rest being lost as heat. This makes them much less efficient compared to newer LED light bulbs, which typically have efficiencies of 80-100 lumens per watt.
1800lumens per watt
About 80 lumens per watt of electric power is normal for LEDs.
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.
LEDs use the smallest amount of electrical power to produce a given amount of light. Approximate data: Incandescent 12 lumens per watt Halogen: 15-17 lumens per watt CFL: 50 lumens per watt LED: 80 lumens per watt Sodium lights as used in street lighting produce 100-200 lumens per watt.
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.
From halogen to LED you can divide by 4 to find the equivalent. Therefore an 80 watt LED would do the job.
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.
Compact fluorescent bulbs are widely used because they use one fifth of the electric power to provide the same amount of light as an incandescent bulb. Incandescent: 12 lumens per watt Halogen: 15 lumens per watt CFL: 50-60 lumens per watt LED: 100 lumens per watt High-pressure sodium: 200 lumens 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.
An LED bulb equivalent to a 35 Watt halogen bulb would typically be around 4-6 Watts. LED bulbs are much more energy-efficient than halogen bulbs, so they require less power to produce a similar level of brightness.
In this context, Watts are a measure of electrical power and lumens a measure of light output. So, depending on the efficiency of your light source the equivalency will vary dramatically. For example, a 60 watt conventional light bulb typically gives off 800 lumens. A frosted 60 watt bulb may only give off 500 lumens. A 13 watt CFL will give off that same 800 lumens, which is why 13 watt CFLs are often (erroneously) called 60 watt bulbs.
Many manufacturers report around 80 to 130 Lumen per watt (lpw), in research/prototyping samsung is reporting 140 lpw and phillips is reporting 200 lpw. the phillips prototypes are not scheduled for mainstream production before 2015.
