You must know which type of flashlight do you need like whether you need a tactical flashlight or military flashlight etc.
The intended use of the flashlight will determine which flashlight is best. There is usually no flashlight that is perfect for all circumstances.
What light do I need
You must know which type of flashlight do you need like whether you need a tactical flashlight or military flashlight etc. For distance, flashlights with deep reflective reflectors that are smooth and durable are the best. Larger flashlights will project a wider beam, which is why they have deeper and wider heads. The Streamlight Stinger DSHPL is an example. It has a large head and a deep reflector, making it one of the most effective distance performers. The light is concentrated by the reflector'sreflector's smooth surface, resulting in a bright beam that can reach far away. Although a textured reflector will give you a brighter beam, they won'twon't shine as far as those with smooth reflectors. The Streamlight Rechargeable Spotlight also excels at distance performance.

What is the measurement of light output
The American National Standards Institute (ANSI), with input from flashlight manufacturers, created performance standards and symbols that effectively communicate benefits and features. These include brightness, runtime and beam distance. They also protect against water penetration and impact resistance. Streamlight and Maglite are now using the ANSI Standards to rate their new models. This will allow you to compare flashlights from different brands.
The Candela is the unit for luminous intensity, and all light measurements can be traced back. Candela, also known as candlepower, is similar to the older unit, candlepower. It was created from a candle with specific dimensions and construction.
Two basic methods are used by flashlight manufacturers to assess the light output of their products.
Total Luminous Output
The Total Luminous Output can be expressed in lumens or Candela. This measure is the total light output of the flashlight, regardless of its beam focus. It is almost entirely a function of the lamp and is equivalent to the lamp output that lamp manufacturers rate in Mean Spherical Candela (Sometimes called mean beam candlepower, which is different from peak beam candlepower) or in lumens. To convert from lumens, multiply the Candela by 12.57. The SL-35X uses a 20-watt lamp that is rated at 450 lumens or 35.8 Mean Spherical Candela.
Peak Beam Candlepower
Peak Beam Candlepower measures the brightness of the beam. It depends on both the lamp'slamp's output and the reflector'sreflector's efficiency. A focused spot of light produces the same intensity as a bare source of unfocused light with the same candlepower. It is produced from the same distance. A flashlight with 20,000 beam candlepower will project the same amount lightly onto a wall as a bare lamp with 20,000 candelas from the same distance. For powerful rechargeable flashlights, the typical beam candlepower values will be in the thousands.
The Total Output system doesn’t doesn’t take into consideration the focusing efficiency and reflectors, so it is impossible to convert between peak beam candlepower and lumens.
All light rating systems are subjective because they depend on the human eye see's perception. The whiteness, or technically the Color Temperature of the light source, is another important factor. The eye will see the brighter source (with a higher color temperature) as brighter than the one with less intensity if they are exposed to two different light sources. The Kelvin scale measures color temperature in degrees. A white flashlight lamp will have a rating of around 3200 K.
Candlepower vs Lumens: How can I convert candlepower into lumens?
Peak beam candlepower measures the brightness of the beam. It is determined by both the output of a lamp and the efficiency and reflector. Peak beam candlepower can be subjective and measured by different flashlight manufacturers. So, it is impossible to compare the brightness ratings of flashlights made by different manufacturers using peak beam candlepower ratings.
Lumens, on the other hand, can be used to compare brightness. It is a measure of all light output, regardless of beam focus.
Peak beam candlepower is an indicator of the reflected sunlight, so it is impossible to convert it into lumens.
BrightGuy'sBrightGuy's website displays light output in peak beam candlepower (also known as candlepower or CP) and/or lumens. These data are directly from the manufacturers.
What is an LED
You haven’t seen a led flashlight in a while. LED flashlights have come a long way. Many LED flashlights now perform better than incandescent flashlights with Xenon or Krypton lamps. The majority of LEDs emit a white light that makes the light coming from a Xenon/Krypton bulb appear yellow. The LED light is generally brighter. Many LED flashlights also have deep reflectors that concentrate light into a narrow beam that shines for longer distances than a flashlight with a Xenon/Krypton bulb. However, flashlights with multiple LEDs, which don’t don’t have reflectors or other special optics, are better for general illumination and will not give you a concentrated beam. The color temperature of LEDs can vary from flashlight to flashlight. Also, light can be slightly blue-green tinted.

What is an HID
HID, or ""High-Intensity Discharge"", is a type o bulb. Instead of using a glowing filament made of tungsten as the light source, HID lights emit from a small glowing ball made of ionized gases. You will get three times the amount of light from a set, and the light output will be whiter than sunlight. Additional benefits of HID include a longer bulb life. HID bulbs can last up to 20x as long as halogen and xenon.
What is considered a hazardous area
Hazardous areas are those that have ignitable concentrations (or vapours) of flammable gases, liquids or dust. These areas are classified according to the potential for flammable concentrations and the properties of any flammable materials.
The National Electric Code (NEC), defines hazardous locations as ""class"" or ""division.""
