Cree is a US-based LED manufacturer. It is well-regarded for its high-quality products and innovation in lighting. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources. The E5R-G4 has a smooth reflector. The right reflector focuses light well. It gives you a better hotspot, and it throws better. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens.

The E5R-G4 flashlight has multiple switch options. They can be useful, adding versatility and convenience to using the flashlight. The flashlight has electronic switches. They have many benefits and extra features compared to mechanical switches. Mechanical switches are usually robust. They resist wear and tear and work in many environments. Rear switches are common on tactical flashlights. Law enforcement, military, and self-defense personnel use them.

The Powertac E5R-G4 flashlight is powered by 1 x 18650 Li-Ion battery. A battery indicator lets users see the battery status. It helps them decide when to recharge or replace the battery. A flashlight's USB charger can be very useful. This is especially true in emergencies. In such situations, access to power outlets may be limited. The flashlight detects when the battery's voltage has dropped to a certain level. Then, it reduces or cuts off the power.

Flashlights without thermal protection may rely on other design elements to dissipate heat. These elements include heat sinks, fins, or body materials with good thermal conductivity. The "8" in the IPx8 rating means the highest level of protection. It is against water ingress.

Accessories, package contents

Package contents18650 battery

It comes with a battery. The battery must be fully charged before you first use your E5R-G4. The holster keeps your flashlight secure. It provides a reliable and easy way to do this when not in use. When gripping the flashlight with the lanyard around your wrist, it gives a more secure hold. It also gives a more stable hold. Replacing worn or damaged O-rings helps a lot. It keeps up the flashlight's durability and performance.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the E5R-G4 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
