I usually use Hernia lights. I google it, due to the different colour temperature, it shows many colours. However, I just want to know what's the difference between the Hernia lights and lasers? How can I distinguish them?

Hello,

Lasers are coherent monochromatic light. There is only one wave length (colour) of light emitted and the waves are in phase with each other. The lights that you are talking about appear to be white light, containing many different colours in the spectrum to create the white colour, and the waves won't be in phase with each other because each colour is a different wave length. The colour difference they are selling appears to be filtered to only allow a certain colour through. All the colours are still being made, they are just blocking the colours they don't want to see. They may be very well focused to have a long narrow beam, and be very bright and intense, but that isn't the distinguishing factor of a laser. If I take the lens off my laser then it will just be a bright wide beam like a flashlight.

Looks to me like "hernia light" is some obscure synonym for metal halide lamp. They're as different from lasers as genetically modified rheostats are from high voltage potatoes.

^ I am still waiting on my GMR from China. Stupid Holiday! Meanwhile, my high V potatoes are being tied in series with a 2000W MOT to drive an Ultra Low Frequency muffler bearing.
