Before You Buy
If you are going to purchase a flashlight you want to make sure it is the right one for your needs. The problem is how do you know which is the right one with so many choices. When purchasing a flashlight you want to consider the primary use of the light. Do you need something small enough to fit in the palm of your hand?

Again how you plan to use the light will play a role. Durability is something else to look at. You want a light built from quality materials. A light that will not shatter and break the minute it hits the ground when dropped.

Users can cycle through the levels via the Mode switch when the light is powered on. Intelligent memory function recalls the last brightness level used when the light is turned back on. Two special modes: Suppressive Light and Strobe Ready. Only one mode can be selected at a time. Switching between these special modes requires you to remove and replace the battery.
Battery Power Indicator

I have spent several hours reading through various online reviews of the Nitecore TM03. What I have discovered in my research is this light is extremely powerful for its size and battery requirements. It really does live up to its reputation of being the most powerful light operating with a single 18650 battery. Most of the reviews that I read through were positive in nature, but as we all know nothing is ever perfect. One of the most notable things about the Nitecore TM03 is its head size compared to its body. The head size has to be bigger because of the LED inside. Another downfall to the TM03 is tail-standing is not possible due to the tail cap switch.
