How do I switch between light modes on the Lumos L2?

With the flashlight powered on, short-press the Mode Button to cycle through the six modes in order: Floodlight, Spotlight, Red Light, Red Laser, Spotlight Flash, and SOS. The device remembers the last active mode and resumes it automatically on the next power-on.

What does it mean when the battery indicator flashes red on the Lumos L2?

A flashing red battery indicator means the remaining charge has dropped below 10%. Connect the flashlight to a certified PD charger via the Type-C port as soon as possible. A full charge from 0% takes approximately 3 hours.

Is the ETENWOLF Lumos L2 Flashlight safe to use in rain or wet conditions?

Yes. The Lumos L2 carries an IPX5 protection rating, meaning it is protected against water jets from any direction and is suitable for use in rain or snow. However, do not submerge it in water or place it where it could fall into a sink or bathtub, as IPX5 does not indicate full waterproofing.

Is it safe to look at the red laser on the Lumos L2?

No. The red laser is a Class 2R product at 650nm with a peak power below 1mW. Never stare directly into the laser beam or point it at human or animal eyes, or at the lenses of optical instruments. Keep the laser away from children unless under adult supervision.

Key Details

This section details the physical controls, light mode sequences, battery indicator behavior, and charging procedure as described in the manual.

Physical Controls

The Lumos L2 has two primary controls on the body:

Power Button: Press and hold for 0.5 seconds to power on. The device automatically activates Floodlight Mode on startup. Press once while on to power off. The device has a mode memory function — it recalls the last active mode and resumes it on the next power-on.
Mode Button: Short-press to cycle through modes in sequence. Press and hold in Floodlight or Spotlight mode to gradually adjust brightness from 100% down to 3%, then back up to 100%; release at any point to lock the current brightness level.

Six Light Modes

Mode	Description
Floodlight Mode	Even wide-area illumination of surrounding space
Spotlight Mode	Concentrated beam with narrow coverage for long-range focus
Red Light Mode	Red warning light for signaling and visibility
Red Laser Mode	Class 2R red laser (650nm, <1mW) for remote indication and pointing
Spotlight Flash Mode	Rapid concentrated strobe for high-visibility alerting
SOS Mode	International SOS pattern: 3 short flashes, 3 long flashes, 3 short flashes, repeated in a loop

Auto-Off Feature

The light automatically shuts off after 1 hour of continuous use. A flashing reminder signal precedes the shutdown. Pressing the Mode Button during this flashing reminder cancels the auto-off program, and the light will remain on until the battery is fully depleted.

Battery Indicator States

The battery level indicator uses three circular LEDs. Each lit circle represents approximately 30% of total charge.

State	Indicator Behavior
Charging (any level)	Three circular white lights flash in cycles
Discharging: 0–15%	One red circle flashing
Discharging: 15–30%	One white circle steady on
Discharging: 30–60%	Two white circles steady on
Discharging: 60–100%	Three white circles steady on
Below 10%	Battery indicator flashes red as low-battery alert

Charging Instructions

Fully charge the flashlight before first use. Connect the included USB-A to USB-C cable to a certified PD (Power Delivery) charger and plug the Type-C end into the flashlight’s input port. Using a PD charger is recommended for best charging performance and stability. A full charge from 0% to 100% takes approximately 3 hours. The input rating is 5V 1A via Type-C.

Standards & Compliance

The ETENWOLF Lumos L2 Flashlight is manufactured and tested to comply with multiple international regulatory and safety standards. The compliance marks printed on the product and its packaging include the following:

Mark / Standard	Scope
FCC	US Federal Communications Commission electromagnetic compatibility and radio frequency compliance
CE	European Conformity marking indicating compliance with applicable EU directives including safety and EMC
RoHS	Restriction of Hazardous Substances — limits use of lead, mercury, cadmium, and other restricted materials in electrical and electronic equipment
IPX5	Ingress Protection rating per IEC 60529: protected against water jets from any direction, suitable for use in rain and snow
Class 2R Laser	Laser safety classification per IEC 60825-1: low-power visible laser (650nm, peak power <1mW); direct eye exposure should be avoided

Additional regulatory symbols visible on the product include the WEEE (Waste Electrical and Electronic Equipment) recycling symbol and the RCM mark, indicating compliance for the Australian and New Zealand markets.

Safety warnings in the manual instruct users to avoid directing the beam or laser at human or animal eyes, to keep the device away from water immersion despite its IPX5 splash resistance, and to use only certified PD chargers. Any malfunction resulting from use of non-certified chargers is explicitly excluded from warranty coverage.

The device remembers the last active mode and resumes it automatically on the next power-on.
Q: What does it mean when the battery indicator flashes red?: A: A flashing red battery indicator means the remaining charge has dropped below 10%. You should connect the flashlight to a certified PD charger via the Type-C port as soon as possible to avoid unexpected shutdown. A full charge from 0% takes approximately 3 hours.
Q: Is the Lumos L2 safe to use in rain or wet conditions?: A: Yes. The Lumos L2 carries an IPX5 protection rating, meaning it is protected against water jets from any direction and is suitable for use in rain or snow. However, IPX5 does not mean the device is fully waterproof — do not submerge it in water or place it where it could fall into a sink, bathtub, or other body of liquid.
Q: Is it safe to look at the red laser on the Lumos L2?: A: No. The red laser is a Class 2R product operating at 650nm with a peak power below 1mW. While brief accidental exposure is unlikely to cause lasting harm, you must never stare directly into the laser beam or point it at human or animal eyes, or at the lenses of optical instruments. Keep the laser away from children unless under adult supervision.
