Fireflies E01 specifications

Flashlights are unlike ambient or overhead lights. They let you aim the light where you need it.

Body, materials, weight, colors

The E01 is small, compact, and designed for ultra-portability. The best flashlight size depends on personal preference. It also depends on intended use and the specific features you want. The aluminium body of the E01 has excellent thermal conductivity. This means it can effectively dissipate heat generated by the flashlight's components. The body of E01 flashlight treated with a Type III hard-anodized, anti-abrasive finish. Factors can influence the color choice of the flashlight body. These include intended use, environment, personal style, and requirements.

System, LED, lens, reflector

Luminus has established a positive reputation as a reliable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The TIR lens of the E01 can reduce light loss. To achieve high light output, it captures and redirects much of the emitted light. The electronic switches may have a higher chance of standby drain.

Performance, flux, intensity, throw

With 2300 lm, the E01 flashlight will offer a brighter and more powerful beam of light. The E01 flashlight has 40000 cd. It can light objects at greater distances. The throw is the distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) measures a flashlight's beam intensity. It compares this to its total luminous flux or output.

Software, user interface, modes

Anduril software offers many output modes. These include different brightness levels, strobe modes, beacon modes, and more. The flashlight has mode memory. It remembers the mode you were using when the light was last turned off. It stays in that mode when you turn it on again. The ramping mode has an advantage. It offers precise control over the light amount emitted by the flashlight. Designers created the strobe function to produce a disorienting or attention-grabbing effect. The SOS code starts three short signals. Then, three long signals follow. Finally, there are three short signals again.

Features, battery, protections

The E01 flashlight's power source is 1 x 21700 Li-Ion battery. It provides reliable, long-lasting energy for top performance. The battery indicator prevents surprise power failures. It ensures the flashlight is ready when needed. The E01 cannot charge batteries. You may need an external charger to keep your battery going. The flashlight detects when the battery's voltage has dropped to a certain level. Then, it reduces or cuts off the power.

The thermal protection feature helps prevent overheating. Overheating can harm the flashlight's performance, battery, and safety. The "8" in the IPx8 rating means the highest level of protection. It is against water ingress.

Accessories, package contents

The lanyard of the E01 protects the flashlight from accidental damage. It does this by stopping it from falling or hitting the ground. When using spare O-rings, follow the maker's instructions. Use their guidelines for proper installation.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the E01 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
