Powertac E9R-G4 (E9RG4) specifications
The presence of a flashlight can provide a sense of reassurance and confidence in unfamiliar or potentially dangerous environments.
|Body diameter||23 mm|
|Head diameter||25.4 mm|
|Material||aluminium alloy with HAIII hard-anodized finish|
The 85 g flashlight may not provide the same level of brightness or features as larger models, it can be handy for quick and convenient illumination in emergency situations or for close-range tasks. 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 bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Anodizing enhances the corrosion resistance, hardness, and scratch resistance of the aluminum, while also allowing for a variety of attractive finishes. 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. This flashlight features a captivating black color.
|Emitter||Cree XHP50 LED|
|Color temperature||6500 K|
|Lens||toughtened AR coated glass|
|Switch||electronic side, mechanical rear|
Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The E9R-G4 has an OP reflector. The advantage of the orange peel (OP) reflector is that it can minimize glare and reduce eye strain, as the diffused light is gentler on the eyes compared to a focused, concentrated beam.
The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The E9R-G4 uses multiple switches. Depending on the placement and design of the switches, a multiple switch configuration can allow for one-handed operation. This is particularly helpful in situations where you need to hold or manipulate objects with one hand while using the flashlight with the other hand.
The E9R-G4 has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation. The E9R-G4 has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness. The placement of the rear switch at the end of the E9R-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.
The 2550 lm output of E9R-G4 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 9702 cd, the E9R-G4 flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances. The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 0.25 lux. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The E9R-G4 has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The strobe function on the E9R-G4 flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect.
|Battery||1 x 18650 Li-Ion battery|
|Charger port||magnetic USB|
The power source of the E9R-G4 flashlight is 1 x 18650 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.
USB rechargeable flashlights have become increasingly popular in recent years due to their convenience and sustainability. When the E9R-G4 flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level.
The E9R-G4 has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. This feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety. The E9R-G4 flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.
