Why are LED lights so bright?
Its because, LED light is usually in a laser light. Lasers are ussually bright, very bright. thats all, i know might be a lie. might not--
What is brighter 2000 lumen watt bulb or a 1500 lumen bulb?
This question is ill posed. Lumen is a unit of measure for how much light comes from the lamp Watt is a unit of measure for how much energy is used by the lamp If the question were; "Which is brighter, a 2000 lumen bulb or a 1500 lumen bulb?" then the answer would be: The 2000 lumen bulb. I think the relation ship between lumen and watt is something like: Incandecent bulbs are 15w/lumen Flourecent bulbs use 40w/lumen LED bulbs are 70w/lumen The way to show the watt and lumen relationship is usually lumens (amount of light) per watt (energy consumption). This is like gas in your car (Miles or KM per Gallon or Liter). Incandescent bulbs have a maximum luminosity of 52 lumens/watt. Fluorescent bulbs range from 46 lumens/watt (CFL) to 100 lumens/watt (T5 and T8 tubes) LED bulbs range from 29 lumens/watt (older, low efficiency) to 100+ (XCree) and they are getting better.
What's does the term Super Bright LED mean?
LED means Light Emitting Diode. They are doped semiconductor and emit light. Super bright led means nothing but they are more bright and powerful. Also they are latest tech.
What is the lumen output of led lamps?
LED light output varies greatly from near-zero to a current maximum of about 400 lumen. It is important to note that the lumen output does not necessarily indicate the potential for a light source to illuminate a surface for the purposes of viewing that surface with the human eye; two lamps putting out 100 lumen may well look to be of different brightness and provide different levels of perceived illumination.
How many lumens for an led replacement vs stock 1157 bulb?
A 150 lumen red LED will be as bright if the tail light lens is red. A 220 red led will be brighter than a regular 1157. The colored lens will make a white led bulb not as brighter due the filtering affect it has on the light wave lengths. A white LED replacement would have to be 400 lumens to equal the 1157's brightness.
What are the disadvantages of LED light bulbs?
Not as bright as normal light bulbs (higher watts though)
How bright is a 3000k led?
It depends on the wattage and how much light the LED emits. 3000K refers to the color temperature of the light and has no relationship to brightness.
Do LED lights on your motorcycle really make you more visable to other drivers?
Depends on the LED light. A 700 lumen LED Bike Light gives off roughly the same light as a 70 watt halogen but for much, much less power. Less lumens = less light = less visability to other drivers.
Difference between lumen's and ANSI lumen's?
Both are unit of brightnes and usually shows numerical value of brightness in projector. lumen is measering unit of each pixel which generates by light source .it tallest brightness away from centre and other mansion is equally distributed cause of generated by led .
How bright is 700 lumen's?
The brightness of 700 lumens can be found in a handheld LED flashlight. The amount of light given off by 700 lumens is enough to brighten any path in front of you. 700 lumens would also be adequate for lighting a small room like a small bedroom.
How many lumen output in a 50 watt power led?
Typically power leds operate as 1-2 watt units. 50 watt is a little excessive for a single led: it would have to be an array. The light output that can be achieved in normal use appears to range from 80-120 lumen/watt, so I guess the answer would be something like 4000-6000 lumen!
What is the best led lighting in the world?
lumen starr is the best led lighting in the world
