Powertac E5R-G4 (E5RG4) specifications

Rated 4/5 based on 1276 user votes.

The E5R-G4 flashlight enhance personal safety and security. It allows you to illuminate dark areas, identify potential hazards, or deter threats by shining light on them.


Weight76 g
Length133.2 mm
Body diameter23 mm
Head diameter25.4 mm
Materialaluminium alloy with HAIII hard-anodized finish

The E5R-G4 is small, compact, and designed for ultra-portability. The length of a flashlight can also impact its balance and weight distribution. A well-balanced flashlight, where the weight is evenly distributed, can be more comfortable to hold for longer periods and reduce hand fatigue. The aluminium body of E5R-G4 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery.

Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. The E5R-G4 flashlight is offered in a stylish black color.


EmitterCree XHP35 HI LED
Color temperature6500 K
Lenstoughtened AR coated glass

The emitter of E5R-G4 manufactured by Cree, a US-based LED manufacturing company. Cree is a well-regarded LED manufacturer known for its high-quality products and innovation in the lighting industry. Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light. The E5R-G4 has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better.

The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. This can increase the overall brightness and efficiency of the E5R-G4 flashlight. The multiple switch configuration on the E5R-G4 flashlight can be a useful option, providing additional versatility and convenience in operating the flashlight. The E5R-G4 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

The E5R-G4 has mechanical switch. Mechanical switches are known for their durability and reliability. They are typically built with robust construction, making them resistant to wear and tear, and capable of enduring various environmental conditions. The placement of the rear switch at the end of the E5R-G4 flashlight facilitates a secure forward grip. This grip allows for better control and handling of the flashlight, especially in situations where precision and stability are important.


Flux1800 lm
Intensity25600 cd
Throw320 m
CD/LM factor14.22

With 1800 lm, the E5R-G4 flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. The E5R-G4 flashlight with 25600 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.

The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output. It quantifies the concentration of light emitted by the flashlight in relation to the total amount of light produced.


Modes5 modes
Mode memoryno
Ramping modeno

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The E5R-G4 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate.


Battery1 x 18650 Li-Ion battery
Battery indicatoryes
Charger portmagnetic USB
Thermal regulationno

The Powertac E5R-G4 flashlight is powered by 1 x 18650 Li-Ion battery. The battery indicator lets you know when the battery is low, charging, or fully charged. The USB charger port on a flashlight can be particularly useful in emergency situations where access to power outlets may be limited. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary.

This light does not have temperature control feature. The "8" in the IPx8 rating indicates the highest level of protection against water ingress.


Package contents18650 battery
magnetic USB charger cable
plastic holster
spare o-ring

It comes with a battery. The battery must be fully charged before you first use your E5R-G4. The holster provides a reliable and convenient way to keep your flashlight securely protected when not in use. When gripping the flashlight with the lanyard around your wrist, it provides a more secure and stable hold. Instead of searching for compatible O-rings or waiting for replacements to arrive, having spare O-rings readily available allows for convenient and immediate repairs or replacements.

The performance of the Powertac E5R-G4 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
