Specifications & Details

Notes

• Avoid shining the beam directly into anyone’s eyes (high-intensity light may cause eye injury).
• Extended high output can heat up the body—use with care to avoid burns.
• Disassembling sealed components is not recommended; it may cause damage and void warranty.
• For long periods of non-use, lock the light or remove the batteries to prevent accidental activation and potential leakage damage.
• After charging, ensure the dust cover is fully closed to maintain dustproof and waterproof performance.
• O-rings wear over time; replace with the included spare O-ring to maintain waterproof sealing.
• If flickering, intermittent light, or failure to turn on occurs, check battery level and polarity first, or clean the contacts (cotton swab with alcohol).
