Alternative Title: The risk of buying a 18650 battery charger not certified by the Underwriter’s Laboratories!
Exploding cell phones and batteries acting like mini rockets, spewing smoke and fire stand testament to the fact that lithium-ion batteries can be very dangerous if the charger used with them does not work as it should. In fact, the numerous horror stories of charred houses and serious burn injuries are enough to prove that a UL certification should be a crucial factor to consider when buying a 18650 battery charger.

On the other hand, with chargers that have a plastic body, there is always the risk of a meltdown. In such a scenario, live wires will be exposed further increasing and even creating the risk of fire.
Ensuring that the safety claims made by manufacturers are for real!
The one thought that comes to mind when checking the features of a 18650 battery charger is the reliability of the safety claims. After all, you can’t expect manufacturers to be forthright about the fire hazards created by their products. If anything, they are bound to underplay such risks.

While scouring the market for the most cost effective, high performance and safe chargers for 18650 batteries, we came across the ZR1 battery and charger set from Brightex Technologies. It is one of the few products currently available that not only has all the safety features mentioned above but also bears the UL certification badge.

The results from the independent, non-profit organization proved that the lumen output of the T6 flashlights stands at a dismal average of around 325 lumens. That is a whopping 675 lumens off the mark.
Brightex flashlights, both of which used U2 LEDs, were found to be brighter with a lumen output range of 600-700 lm. Incidentally, the company never claimed to offer more than this. The results of the tests can be found on the website of Brightex.
But, you may be getting less than 300 lumens from your flashlight!
Remember that the flashlights tested were among the more popular products in their category, yet the claims made by their manufacturers fell flat when tested by an independent body. The very first thing that you need to understand is that no single LED bulb currently available offers 1000 lm brightness for a portable, battery operated
