Olight I-15 Flashlight Specifications

Uses the latest premium high-performance Cree XR-E R2 LED with a lifespan of 50,000 hours
Smooth power adjustment in the range of 6-140 lumens (1.2 or 1.5 V AA batteries) or 6-205 lumens (3.7 V 14500 li-ion) with a runtime of 50 - 1 hour. Also features SOS and strobe flashing modes.
The flashlight is powered by one AA battery. Alkaline, rechargeable NiMH batteries, and Energizer L91 Ultimate Lithium disposable batteries (providing the longest runtime and functioning in temperatures far below freezing) can be used. The flashlight is also compatible with a 3.7 V 14500 li-ion battery and achieves higher performance with it.
The flashlight's electronics maintain a constant current to the LED, so the light intensity does not decrease as the batteries drain.

The flashlight is waterproof.
Tactical button switch at the end of the flashlight with momentary activation function with a light press.
Hardened lens with an anti-reflective coating.

Package includes a wrist strap, two O-rings, and a rubber switch cover.
A red or green filter and a white diffuser can be purchased in addition to the flashlight.
Operation: The flashlight is turned on by pressing the button at the end of the flashlight. By quickly turning the flashlight off and on, you switch between constant lighting mode - strobe - SOS. The smooth power adjustment in the range of 6-140 lumens (6-205 with a 14500 battery) allows for the new "infinite beam adjustment" function, which is activated by turning the head about a quarter turn in constant lighting mode. In this mode, the flashlight gradually changes the output light power. By tightening it again, the currently set level is remembered and retained even after the flashlight is turned off.

Warning:

Use only high-quality batteries to prevent damage to the flashlight, such as leakage of substances from the battery.
Remove the batteries from the flashlight if it will not be used for an extended period or if the battery is already discharged. Otherwise, damage to the flashlight may occur with some lower quality batteries.
Insert the batteries with the positive pole facing towards the head of the flashlight.
If the protective rubber rings appear damaged after prolonged use, replace them. The rings should also be lubricated to prevent rubber erosion. By following these rules, the flashlight will be properly protected against water.
If the flashlight flickers or does not turn on, it may be caused by:
           o The batteries are almost discharged - replace them.            o The contacts inside the flashlight are dirty - clean them with a cloth soaked in alcohol.            o The head, body, or end of the flashlight is loose - apply lubricant to the sealing rings and tighten the head and end of the flashlight firmly.
