Best Mechanic Flashlights Buying Guide

What to Consider When Buying a Mechanic Flashlight

  • Bulb Type

Nowadays, LED has become the bulb of choice in a market that was once limited to incandescent bulbs. This is due to the technological innovations that turned LED into an energy saving light source that produces less heat than the average krypton light bulb. The run time, impact resistant and brightness modes of  LED flashlights are also hard to compete with.

  • Beam Type

Choosing the right beam type depends on how and where you are going to use your flashlight. There are three beams to choose from. The first one is a flood or fixed beam that comes in single beam width. This beam is more suitable for every day use and can come in handy during camping trips as well. The second option is a spot or focused beam that was designed to pierce the darkness and provide long-distance illumination. The third and final option is more versatile and can be used in different situations since it can be adjusted from wide to focused with more settings to choose from in between.

  • Regulated Output

A flashlight with a regulated power supply will sustain a brightness level that is consistent throughout the shelf life of its battery. In contrast, unregulated lights gradually lose their brightness as the power drains from their batteries.

  • Battery Type

Batteries also influence our decision when it comes to buying portable items such as flashlights. Disposable batteries, especially the CR123A are usually favored for their high voltage output and small size. They are also far from heavy but more expensive than the standard double A and triple A batteries. Investing in rechargeable batteries is another great option for environmentally conscious buyers who want to cut back on using disposable items, and those can be recharged using a USB cable. This cable can be connected to a laptop or even a solar panel. Another environmentally friendly option comes in the shape of renewable batteries that are powered using solar panels or a hand crank. Eco-friendly flashlights make a great addition to any survival kit.

  • Modes

Professionals who need a flashlight with multiple settings will go for a model that can offer them special features such as strobe and SOS. Having different modes at your disposal can come in handy, especially at night or during emergencies at work or at home. Bright modes use up more battery power and therefore have less runtime when compared to low and medium settings. Some flashlights offer programmable modes and a memory feature that automatically saves your last used setting.

  • Controls

User-friendly flashlights have functional on/off buttons that allow you to switch modes with ease. These flashlights usually have push buttons or slide switches that can be operated using one finger. Others have a rotating bezel that also doubles as a switch. Some models have a safety lock that is convenient for pocket lights that can get accidentally turned on. This feature works in favor of the battery since it will prevent the flashlight from draining it by mistake. Silent insta-beams are also a bonus feature that can be found in certain flashlights. This particular feature is ideal for professionals who need an instant flood of light without having to scroll through all of the available settings.

  • Materials and Shape

Both plastic and aluminum alloy are the materials of choice when it comes to manufacturing the best flashlights. Stainless steel is sometimes incorporated into the design to make the flashlight more impact resistant. Not all flashlights have the same degree of durability.  Those with a thick aluminum body are usually tougher than your average slim led torch. Some manufacturers have come up with ways to prevent the flashlight from rolling out of reach or slipping from a person’s fingers. Therefore, most quality flashlights have an anti-slip surface with rough ridges to reduce slippage.

Types of Flashlights

  • Incandescent

Flashlights with incandescent bulbs were used long before the invention of the LED. Incandescents are cheaper but they are also known for wasting energy. They emit more heat as well and this drains the battery at a much faster rate when compared to LED bulbs.

  • LED

LED flashlights are one of the most powerful flashlights on the market. In addition to saving energy, they also have a longer shelf life when compared to incandescent bulbs. Their durability lies in the absence of glass and filament from their design. The durability and longevity of this type of flashlight also affect the lifecycles of its bulb and batteries. These bulbs might be more expensive but they are incredibly cost-effective in the long run. LED flashlights are now sold in a wide array of colors including regular white light.

  • HID

Flashlights with high-intensity discharge bulbs (HID) generate an ultra-bright light that is capable of cutting through the darkness like a sword. These special bulbs require an electric current to flow through a ball of ionized gas, therefore, they are usually expensive and the flashlight itself is bigger than your average LED torch.

  • Xenon, Halogen, and Krypton Bulbs

The brightest flashlights available are powered using either krypton, halogen or xenon bulbs. Pressurized gas is often used to prolong the shelf life of the filament located inside each of these bulbs. This allows the bulb to burn brighter without impacting the battery.

  • Shake Flashlights

Shake flashlights are ideal for emergency situations since they rely on magnets instead of batteries. Also known as Faraday flashlights, these torches work by shaking them for a period of sixty seconds. This motion allows you to use the LED light for several hours. The light itself is not as bright when compared to battery operated torches but it can come in handy in the absence of other portable light sources.

  • Headlamps

Headlamps offer a hands-free alternative to regular flashlights. Many headlamps come with various brightness levels and a rotating head that allows you to angle the flashlight in any direction of your choosing. These convenient features make it ideal for all kinds of professional and recreational activities.

  • Penlights

Penlights are also a lightweight alternative to regular flashlights and they are small enough to fit inside pockets and tool boxes. Some of them are fitted with a reversible clip so they can be attached to helmets, making them a great hands-free alternative to regular flashlights.

What is a Lumen?

Measuring the amount of light that is visible to the human eye is possible thanks to a unit of measurement called the lumen (lm). Bulbs with a high lumen will shine brighter than those with a low lumen rating. The average household lightbulb is capable of generating anything between 300 and 1000 lumens and the most powerful flashlight tends to generate more than 20,000 lumens.

What is a Candela?

The brightness of a light source is measured using the candela, so it is the standard unit of luminous intensity in the International System of Units (SI). In other words, the candela is the measurement of the brightest spot inside a focused beam.

Best Mechanic Flashlights FAQ:

Q:  Are there ever times you wouldn’t want a high lumen flashlight?

High lumen flashlights are great if you need to flood a room with light or if you need a powerful beam that can slice through the darkness of a forest. However, if all you need is a more focused light with longer runtime, then you are better off using a low lumen flashlight. At the end of the day, it all depends on the nature of your work.

Q:  Are there differences in run time among the different types?

Yes. High lumen flashlights that deliver long-range illumination will have shorter run times compared to their low counterparts.   Flashlights designed for everyday use have long regulated run times.

Q:  Why would I want LEDs instead of Xenon lamps?

LED lamps are more durable and energy efficient. Moreover, their life expectancy is around 50,000 hours. They are also made of solid material without any filaments or breakable components, unlike xenon lamps that are more fragile and less energy efficient.

Q:  Can I use rechargeable batteries with LED flashlights?

  Yes. As a matter of fact, many quality flashlights come with their own rechargeable batteries. small flashlight on the table
