| Body diameter | 22 mm |
| Head diameter | 23 mm |
| Material | aluminium alloy with HAIII hard-anodized finish |
| Colors | black |
The 50.5 g flashlight would be considered extremely lightweight for a handheld flashlight. The length of the E1 flashlight can affect its portability. A shorter flashlight is generally easier to carry in a pocket, bag, or pouch, making it more convenient for everyday use or when you're on the go. Aluminium is a lightweight material, which is beneficial for E1 flashlight. 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 comes in a sleek black color option.

| Reflector | TIR |
| Lens | TIR |
| Switch | dual electronic 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 TIR lens of E1 consists of a single-piece lens made of a transparent material, typically acrylic or polycarbonate. Its shape and internal geometry are designed to achieve specific light distribution patterns, such as flood or spot beams, by manipulating the behavior of light rays.
The E1 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 rear switch of E1 is typically operated with the thumb or finger, making it easily accessible and convenient to use. The positioning of the switch at the rear of the flashlight allows for natural and intuitive operation, particularly in one-handed scenarios.
Performance
| Flux | 1000 lm |
|---|---|
| Intensity | 9025 cd |
| Throw | 190 m |
| CD/LM factor | 9.03 |
The 1000 lm output of E1 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 9025 cd, the E1 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. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.
Software
| Modes | 4 modes |
|---|---|
| Mode memory | yes |
| Ramping mode | no |
| Strobe | yes |
| SOS/Beacon | yes |
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The E1 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 E1 flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect. The E1 has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.
Features
| Battery | 1 x special 18650 Li-Ion battery |
|---|---|
| Battery indicator | no |
| Charger port | yes, on special battery |
| LVP | yes |
| Thermal regulation | yes |
| Protection | IPx8 |
| AUX LEDs | no |
| Magnetic | no |
The power source of the E1 flashlight is 1 x special 18650 Li-Ion battery, providing reliable and long-lasting energy for optimal performance. When the E1 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 E1 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 E1 flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.
