A 1000 lumen flashlight is quite bright and, depending on the lens or reflector design, powerful enough to reach a distance of 200 meters or more. This type of flashlight allows you to see objects from a far distance. In order to achieve 1000 lumens, these powerful flashlights need the ...
The light is very directional. A laser light has a very tight beam and is very strong and concentrated. A flashlight, on the other hand, releases light in many directions, and the light is very weak and diffuse. Stimulated Emission To make these three properties occur takes something called...
Measured inlumens. This is a measure of the intensity of the light coming out of the flashlight on the highest brightness setting powered by new batteries. It may also be shown for multiple light settings. This is a great comparison tool, but does not tell the whole story about brightness....
How bright is an Android phone flashlight? Most modern Android smartphones have fairly bright flashlights capable of producing enough light for most scenarios. Common flashlight LEDs in smartphones range from around 40 to 50 lumens. Yet it’s important to note that not all devices will have the...
A fluorescent light contains low-pressure mercury vapor bouncing around to produce ultraviolet light. Fluorescent lights are more efficient than incandescent light. They are capable of generating up to 100 lumens per watt, similar to the output of HMI. So what's that mean? It means that the sp...
A basic hologram is easier to setup than you might think. HowStuffWorks It doesn't take very many tools to make a hologram. You can make one with: A laser: Red lasers, usually helium-neon (HeNe) lasers, are common in holography. Some home holography experiments rely on the diodes fro...

Many have a frosted outer plastic case or "diffuser" to spread the bright, highly directional flashlight glare of their little LEDs into a warmer, fuzzier glow more suitable for home lighting.How LED lamps work One LED would normally run off something like a 1.5-volt DC (direct current) ...
Torch/flashlight power is measured in lumens. The higher the number, the more powerful they will be. You also have full RGB mini lights, from various manufacturers like Aputure, which offer alternatives to torches. Gels For light painting photography, gels are a must if you’re using torches...
Luminance. A measure of how much light is reflected at different angles. Your perception of the brightnessa flashlight puts out is determined not only by lumens but also by other factors. For example, a flashlight with 900 lumens and a standard lens will shine more brightly on an object in...
