The new iPhone flashlight is a great resource to have. However, you might be wondering how many lumens it really has. This article will explain all of that information to you!
Is a tool required to change batteries? Light Output Measured in lumens. 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...
Does light travel as a wave, a ray or a stream of particles? Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think ...
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...
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...
One way to compare lamps is by looking at how much energy they need (measured in watts) to produce the same amount of brightness (measured in lumens). Dividing these two numbers, we get the number of lumens each lamp can produce for a single watt of energy. Looking at the chart here,...
How to use a flashlight or other light to spot building contaminants on surfaces. The fact that mold is "hidden" or hard to spot on some surfaces in buildings does not mean you cannot find it. While this is perfectly obvious to some folks, too many of us haven't considered that is yo...
Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think scientists know all the answers, but light continues to surprise them. He...
I carry ahigh-lumens pen flashlightto every event. A violent person who gets flashed in the eyes will be stunned momentarily. This is a pretty good video showing that a flashlight is capable of much more than you imagined. Do you need a generator for Coronavirus?
Do not underestimate the value of having proper lighting. A combination of 12 tea lights / candles were enough to keep the three areas of the house lit and to provide some comfort. Artificial lights like the LuminAID lantern and a strong 900 lumens flashlight came in real handy. In retrospe...
