A butane torch is a type of lighter that can produce high-temperature flames. It is utilized in various industries, including the culinary arts, jewelry making, soldering, brazing, and welding.

It has some night vision properties, but you’ll have a more natural view of your surroundings in the dark. It’s almost like a dulled down bright white light. Throw in the added glow of invisible fluorescent liquids and that makes blue light perfect for following blood trails and looking for invisible fluids. We could talk about the brightness of these torches, which across the board is pretty similar, or the size and weight. Given that at least two of these designs are replicated in more than one example, there’s plenty to choose from if you want a very compact torch, or one that is a bit bigger. Cost would also usually come into it but the price range is hardly noticeable, and bear in mind that while most of these are usable in heavy rain, none are actually waterproof, so no matter which one you choose, don’t go immersing it in water! That’s why blue light is commonly used to spot bloods, oils, chemicals, and anything else with fluorescent properties. Liquids that are usually invisible to the eye will take on a fluorescent glow when blue light is shined on it. I’ll go over the different applications where you can use a blue flashlight below, but here are the main benefits of blue light flashlightsA beetroot can be eaten to restore {{hunger|1}} [[hunger]] and 1.2 hunger [[Hunger#Mechanics|saturation]].

Reflected UV photography is a different ballgame altogether which requires bespoke uv-transmission optics, filters, lighting and ideally a converted camera - not an exercise for the faint hearted. style="text-align:center" |29.13% When a forensics team is investigating a crime scene they use a combination of blue light and luminol to make invisible stains glow in the dark. They start off with using blue light to identify potential blood, body oils, semen, saliva, etc. Blue light helps with initial detection, but spraying on luminol is what really makes blood shine This is even one of those well-built small tactical flashlights that is small enough to be an everyday carry item. |snap=14w26a|[[File:Melon Stem Age 0 JE6.png|32px]] [[File:Melon Stem Age 1 JE6.png|32px]] [[File:Melon Stem Age 2 JE6.png|32px]] [[File:Melon Stem Age 3 JE6.png|32px]] [[File:Melon Stem Age 4 JE6.png|32px]] [[File:Melon Stem Age 5 JE6.png|32px]] [[File:Melon Stem Age 6 JE6.png|32px]] [[File:Melon Stem Age 7 JE6.png|32px]] [[File:Attached Melon Stem (N) JE4.png|32px]] [[File:Attached Melon Stem (E) JE4.png|32px]] [[File:Attached Melon Stem (S) JE4.png|32px]] [[File:Attached Melon Stem (W) JE4.png|32px]] Melon stems now correctly render as crosses again.{{bug|MC-58136}}}}

In fact UV UVIFL (UV-induced visible fluorescence photography) has never been more accessible than it is today, and combining this with extreme macro has the potential for some quite fascinating and unusual macro images. Reflected UV vs. UV Excited Fluorescence Red is by far the best color for preserving night vision, but green light helps improve contrast and clarity in your surroundings. Blue light is better than white for seeing in the dark, but that’s not its main purpose. Blue light therapy is now one of the go-to treatments to relieve seasonal depression. Researchers have found that it’s also an effective treatment for depression that isn’t seasonal, especially when combined with antidepressant medications.

Blue lights are commonly used by hunters, forensics teams, fisherman, and in industrial applications where you need to find invisible fluids. The fluorescent properties found in most fluids and oils will glow under a blue light. As mentioned already, there are plenty of outdoorsmen who love having a blue light on hand, and a blue light flashlight is definitely more convenient. For night fishing the use of blue light is two-fold: it makes it easier to see fish at night while making it safer on your boat (or on your on-shore setup) and in some situations it attracts certain types of fish, bringing them close to give you a shot to actually catch them.
