What You Should Know Before Buying olight flashlights

Built Quality

The quality of a flashlight depends upon several factors like impact resistance, water resistance, and brightness. The impact resistance of a flashlight is measured in meters and tested by dropping the flashlight up to a certain depth. Water resistance of a flashlight is measured by IP ratings – the higher the rating, the more water-resistant the flashlight is. The brightness and the total output light of a flashlight can be measured through its candela rating and lumens. You will find all this information either written on the flashlight itself or its manual.

Lumens and Light Output

Lumen is a measure of the flashlight light output – so the ideal lumen number will depend on your situation. Usually, a flashlight with 300 to 1000 lumens is considered versatile enough for everyday use and frequent nightly tasks. But the number can go up for certain tasks that require more light output.

For reading or random everyday tasks, you will find a 300 lumens flashlight to be useful enough. For camping or similar outdoor activities like nightly walks or running, a 300 to 900-lumen flashlight will work well. If you’re hunter or military personnel, you may need to spot your prey or a threat from a considerable distance – for such situations, pick a flashlight with a light output of 1250-2500 lumens.

Flashlights with a higher light output than 2500 lumens are usually used in search and rescue operations as such operations require a much-focused illumination.

Battery Type

The best battery type for your flashlights depends entirely upon your use. Whether you want it to be rechargeable, or disposable. Do you need to use them right away or after a while? The size and the weather in which the flashlight will be used also matters. The most common rechargeable batteries are alkaline batteries. Found in AAA, AA, C, and D types, their nominal voltage is 1.5V and they have a self-discharge rate of approx. 2-3% per year, making them an excellent and easily available choice if you want a disposable battery for an emergency flashlight that is stored most of the time. If you want better performance in rechargeable batteries, go for lithium batteries. With a nominal voltage of 3V per cell and extreme weather endurance, they are perfect if you are looking for a disposable battery with a lower discharge rate than alkaline batteries. The only con is that they are more expensive than alkaline batteries.

If you want rechargeable batteries, as they are far more cost-effective in the long run, there are two options available – Lithium Ion and NiMH batteries. NiMH can be found in standard alkaline battery sizes but Li-Ion batteries come in their own standard sizes like 18650. NiMH batteries last longer than standard alkaline batteries despite having lower (1.25V) voltage owing to their lower discharge rate.

With a nominal voltage of 3.7V per cell Li-Ion batteries beat every other battery in terms of energy density, although its prices are reflective of that. Read the instruction manual of your flashlight to pick the best battery option for yourself. Also, consider your requirements and the use of your flashlight (emergency use, everyday use, etc.).

Run Time

The run time of a flashlight primarily depends upon its batteries. Li-Ion batteries have the highest energy capacity and they are also rechargeable. While alkaline and lithium are long-lasting disposable batteries. Other factors that affect the run time of a flashlight are its power draw i.e., its brightness setting, light output, and the number of batteries. A flashlight will last longer on a lower brightness setting than on a higher one. Flashlights with the lowest lumens will last the longest. Also, the higher the number of batteries the longer the run time of a flashlight. Choose the variables that best suit your situation.

Beam Intensity

Many people confuse lumens for the measure of flashlight brightness or beam intensity. Lumens are merely the measure of total light output generated by a flashlight. The beam intensity depends mainly upon candelas. Different candela settings provide different beam intensities – from highly focused to wide and dispersed. Purchase a flashlight with a higher candela rating if you want a long-distance or more focused beam. Alternatively, get a flashlight with a low candela rating for more uniform illumination. Other factors that affect beam intensity are the size and shape of the lens or reflector.

Questions and Answers About olight flashlights

How many lumens is a good flashlight?

This depends on what function you want the flashlight to fulfill. An EDC (everyday carry) used to illuminate the indoors and maybe even outdoor camping activity only requires 20-150 lumens. If you require a longer throw and better light, such as required in a search-and-rescue, it can go up above 1000 lumens.

What is the strobe function on a flashlight for?

Bright, flashing lights are disorienting and can be used as a self-defense measure. Flicker vertigo or Bucha effect is a result of flashing pulses of relatively bright light which can induce disorientation/vertigo/nausea. The strobe function can also act as a distress signal as a secondary function.

How do you signal SOS with a flashlight?

The way to signal SOS with a flashlight is to use morse code. Three short and rapid 1-second flashes followed by three longer 2-second flashes and finished with three rapid 1-second flashes again. This spells out S-O-S in morse code and is universally recognized to be a distress signal.

Do LED Flashlights Get Hot?

Yes, LED flashlights do get hot but nothing too hot to the point where it is hard to hold onto it. As with any electronic device, prolonged usage at a high intensity will cause the inner mechanics to heat up. The amount of heat given off by an ED flashlight is directly proportionate to the amount of energy it is using to power the light. However, LED flashlights are considered ‘cool’ lights which means that they give off lesser heat as compared to the traditional halogen/incandescent lights.

Can LED flashlight bulbs be replaced?

Yes, LED flashlight bulbs can be replaced as long as you manage to find a brand/model that you can replace with the one you have. It needs to fit within the receptor and have the proper voltage capacity to work with the batteries within your flashlight.
