The stated 7.5-hour average battery life is likely a simplified figure representing typical usage across all modes or a weighted average. In practice, the 80-lumen low settings (both 6000K and 3000K) are rated to last up to 10 hours on a fresh set of 3 AAA batteries. The 140-lumen high mode is rated for 5 hours. Users can expect performance closer to the mode-specific times, with the 7.5-hour figure being a general guideline rather than a strict limit for any single mode.

Alkaline AAA batteries, commonly included, experience a significant performance drop in cold temperatures. At -5°C, their effective capacity can decrease by 15-25%. This means the advertised 10-hour runtime on low might reduce to approximately 7.5-8.5 hours, and the 5-hour runtime on high could be closer to 3.75-4.25 hours. For consistent performance in freezing conditions, consider using lithium AAA batteries, which maintain their voltage and capacity much better down to -20°C.

An official IP rating is not provided for this specific 4-pack model. However, similar portable LED camping lanterns often offer at least an IPX4 rating, providing protection against splashing water. For these Lepro units, it's advisable to avoid direct exposure to heavy rain or submersion. In humid environments, ensure the battery compartment cover is securely sealed to prevent moisture ingress and potential internal fogging or corrosion, which could affect the 4.5-volt DC circuitry.
