EDC flashlights are amazing and will provide you with the light that you need and for shorter use. Normally, small flashlights like this one cannot be relied on by a person who wants extremely bright light that covers a wide area. This is meant for emergencies, and they don’t usually last long. But they can allow you to change your tire or find your way home when there is a blackout.

Why buy the Streamlight Microstream C4 flashlight?

  1. People want products that will last. So, when buying a flashlight, the first thing to look at is how durable the light is. Streamlight Microstream is constructed from a corrosion-resistant machined alloy case with a Type II MIL-Spec back hard-anodized finish. In addition, it has an unbreakable and scratch-resistant polycarbonate lens that is O-ring sealed. These materials make this flashlight very durable and reliable to use.
  2. It has a maximum of 28 lumens. This is bright enough to offer the user light that covers a few meters. The beam distance of the light goes up to 52m and 683 cd. This is great for such a small tactical light.
  3. It is powered by one AAA alkaline battery. These batteries can be easily found on the market. Also, they are cheaper compared to lithium-ion batteries. They enable the torch to illuminate for 2 hours and 15 minutes before needing to be changed.
  4. The flashlight is very light, and this makes it outstanding for outdoor use. It weighs just 1.04 ounces.
  5. Storing the flashlight when not using it isn’t an issue as it has a pocket clip to attach to your pocket or on the backpack as you go about your duties.
  6. You can rest assured that you are getting a quality product and not throwing away your cash. This is because the manufacturer offers a lifetime limited warranty. So, if the flashlight has an issue, the company will look into it and replace it.

What to look for when buying a small pen flashlight?

Construction – this is the first thing that you should look at when searching for the best flashlight. If the flashlight is made from poor materials, then it won’t last for long. The moment it crashes or falls, that will be its end, or it will start functioning poorly. Consider acquiring flashlights that are made from quality materials like polymer and aluminum. Streamlight is very keen on quality, and you will find that most of their flashlights are built with either polymer or anodized aluminum. Besides tactical pen, you can check the best-selling electric pencil sharpeners which is also a handy tool.

Type of battery – the second thing to consider is the type of battery that powers the light. Not all batteries offer the same results. For instance, alkaline batteries don’t last long when compared to lithium-ion batteries. Lithium batteries have a longer run time and can be kept for several years. Alkaline batteries are easy to find and are as well cheaper. If you’re going to an area where there is no electricity or won’t be able to recharge the lithium batteries, having a device that uses alkaline batteries is a great idea. This is the case with the Streamlight Microstream light.

The number of lumens – the brightness of a flashlight is determined by the number of lumens it uses and the type of bulb it has. Most of the latest flashlights use LED bulbs that are impact-resistant and have more hours when compared to incandescent or any other type of bulb. If you want a very bright light, then you should go for one with a higher number of lumens. The brighter the flashlight, the more battery power is utilized and the shorter the run time.

Purpose of the light – before you choose a particular flashlight, you should consider what you’re going to use it for. Brands like Streamlight have several lights on offer for different uses. They provide keychain lights, tactical lights, EDC flashlights, weapon lights, and many others. Knowing the torch you want will help you benefit more and have a simple time using the device. The Streamlight Microsteram EDC flashlight is suitable for camping, home, and even for emergency use.

Price – don’t buy a flashlight because it is highly-priced. Buy a flashlight because it has the features that you’re looking for. Some LED lights are highly-priced but don’t live up to expectations. Consider looking at online reviews for the best lights for different functions. Streamlight has different lights at different prices, but they are very reliable. Most of their flashlights are favorably priced but still deliver quality results.

Brand – the brand from which you buy your flashlight matters a lot. This is because there are brands that pose as the best but offer poor products. Ensure that you go through different online reviews before buying a particular flashlight. One of the notable flashlight brands is Streamlight. It creates quality flashlights and can be relied on in different weather conditions.


Having a flashlight with you can mean a lot. Nobody knows when they will need it but having it makes you feel safe and well prepared. If you are like me and don’t like carrying heavy things, then the Streamlight Microstream flashlight is a great light to have. It is compact in design and comes with a clip for attaching to your pocket. It is sturdily built and can withstand tough conditions. The 28 max lumens it comes with are enough to offer you bright light in your room or on your path to home. When you buy this light, Streamlight offers you a lifetime limited warranty. I hope this Streamlight Microstream review article has given the right direction about this flashlight.

    A friend game me a Microstream when i retired. Have enjoyed and used it over the past 4 years. Picked
    up from my desk drawer yesterday and it did not come on. Changed the battery, still no light. Not sure if the bulb can be changed, but am certain I have not used it for 30,000 hours.
    Can you offer suggestions? I really like this light and it has sentimental value.
