When purchasing any type of product, there are a number of factors to consider. There’s a lot to consider even with something as deceptively simple as a flashlight.
Sure, the size, durability, and battery life are all significant, but this is a flashlight, and the bulb quality is possibly the most crucial factor of all. What is the brightness of that bulb? How long do you think it’ll last? How far does a light beam actually travel?
They’re all valid questions to ask yourself before purchasing a flashlight, and as you probably already know, the answers are mostly dictated by the type of bulb used in the flashlight in question.
So, what are the many types of flashlight bulbs, how do they work, and what are the benefits and downsides of each?
4 Types Of Bulbs
The incandescent bulb is the first sort of flashlight bulb to consider, as it is also the type of bulb and flashlight that has been around for the longest time.
Now, this type of flashlight bulb isn’t expensive to buy in the first place, which is wonderful, and they’re fine for basic and infrequent use around the house, such as when the power is out for a couple of hours, but that’s about it. Although incandescent flashlights are the oldest, they are far from the best.
For starters, incandescent lamps aren’t very long-lasting. With regular use, you’ll find yourself replacing that bulb in no time, which will cost you money. There’s also the problem that this style of bulb isn’t particularly efficient. They aren’t particularly brilliant in terms of power consumption. Sure, they’re bright enough to offer some illumination, but they’re no match for current LED and HID lights.
These devices waste a lot of energy, which means they’ll empty your batteries quickly and necessitate frequent battery replacements, which will cost you more money. There’s also the issue that incandescent bulbs aren’t particularly long-lasting. When you drop an incandescent flashlight, it nearly always breaks. Finally, these items are not environmentally friendly because they consume a lot of energy.
In other words, if you need a good flashlight, you should generally avoid incandescent bulbs.
Xenon, Halogen, & Krypton Bulbs
The xenon, halogen, or krypton variety of flashlight bulbs should be considered next. This sort of flashlight bulb is still incandescent, but with one significant distinction. The distinction is that, in addition to the filament, there is a pressurized gas inside the glass, commonly xenon, halogen, or krypton.
This is a step up from a typical incandescent bulb since the pressurized gas allows the filament to burn brighter and longer without wearing out as quickly, all while consuming less energy.
In fact, when it comes down to it, these are the brightest flashlights you can get.
In actuality, they don’t make good survival flashlights because they’re still fragile, their battery life isn’t fantastic, and their total lifespan isn’t comparable to other flashlight bulb kinds, particularly LED.
High Intensity Discharge Bulbs
High-intensity discharge, or simply HID bulbs, are the least frequent of the unusual flashlight bulbs. A sealed ball packed with ionized gas is used in this sort of bulb. An electric current is then fed through the gas, causing it to light up thanks to the wonders of science.
This sort of flashlight bulb is likewise extremely brilliant, almost as bright as the xenon bulbs mentioned above. In addition, the bulbs are usually highly sturdy and long-lasting.
However, due to their bulkiness, they aren’t exactly perfect for transportation and survival requirements. Furthermore, HID flashlights are typically highly expensive, much above what most people are prepared to pay.
The LED bulb (light-emitting diode) is the last sort of flashlight bulb to consider, and this is the one you want for survival flashlights. LED lights, for example, lack the glass and filament seen in other bulb types, allowing them to be more resilient and long-lasting.
Some LED flashlights have a 100,000-hour or longer life span. Many LED flashlights have good impact resistance, which means they won’t break if dropped (to a reasonable extent), and some are even shockproof and waterproof (also to a certain extent).
Furthermore, LED flashlights use far less energy than incandescent and other bulb types. The energy from the batteries is used to produce a lot more light, whilst other bulb types emit a lot more heat. In this perspective, heat is simply wasted energy. On that topic, the fact that LED lights do not get hot is another factor that contributes to their longer lifespan.
Furthermore, LED lights are the most energy-efficient on the market, both in terms of consumption and conversion. In other words, you won’t have to replace the batteries in an LED flashlight nearly as often as you would with other bulb types, and some of the more current models even have rechargeable batteries.
LED flashlights can be pricey, but prices have dropped dramatically in recent years. However, because they last a long time, provide a lot of light, and require little battery power, they can be considered as very cost-effective in the long term. Simply told, the LED bulb is the way to go if you need a good survival flashlight. It is long-lasting, brilliant, and energy-efficient.
Bottom Line Different Types of Flashlight Bulbs You Might Need In An Emergency
That’s all there is to it when it comes to the many sorts of bulbs that flashlights may come with. You may now make an educated decision about what is best for you. Again, when it comes to survival flashlights, LED is the way to go.
