Pros and Cons

  • The LR40R uses standard 4 x 18650 Li-ion batteries, but it can run on a single battery for a couple of minutes. Moreover, it can be fast-charged using the USB c type port.
  • It has amazing brightness features and has the potential to light up an entire football field or your back garden. Its wide and narrow beam comes with two dedicated buttons making it a flawlessly constructed lighting tool to meet all of your needs in the dark.
  • You don’t have to be part of a Search and Rescue Team or be someone who occasionally goes camping to purchase and enjoy the benefits of owning an LR40R, even if you are into DIY projects indoors, you can use it to lighten up your space or even to tend to your garden in the evenings after an exhausting day in the office.
  • When it’s on the turbo, it can warm up quickly but it has an internal function that allows it to regulate its temperature down which makes it valuable for cold nights outdoors or early morning walks with your dog.
  • It can be used as a phone charging device and it does the job efficiently.
  • Even though it has been lauded for its durability and functionality, it is a costly flashlight to purchase. If you are planning on buying one, you need to be prepared to part with a significant amount of money.
  • Although it warms up when in full power turbo, some consumers feel as though this is a downside because it can get significantly hot and decreases the battery by a margin.
  • The brightness can be harmful to your eyes and lead to temporary blindness if there is accidental exposure. You need to use the LR40R carefully and it should be kept far from the reach of children and animals. If used incorrectly, the brightness has the potential to start an accidental fire.
  • The light distribution is suitable for people who are shortsighted because of the very narrow beam. So, if you have excellent eyesight, it can be a bit of an issue to navigate.
  • It is not as compact as the pictures advertise, some reviews mention that it is sturdy and bulky and it is a tad difficult to locate some of the buttons to power it on or switch modes in a potentially life-threatening situation in extreme darkness.
