Cree LEDs are commonly used in a wide range of lighting applications. Their products are trusted by lighting professionals and have gained a strong reputation for quality and performance. The choice of color temperature depends on the specific lighting application and personal preferences. With the smooth reflector of the I331, the beam tends to have a well-defined hotspot at the center, which provides a concentrated beam of light for long-range applications.
The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. This can increase the overall brightness and efficiency of the I331 flashlight. The I331 has mechanical switch. Mechanical switches are known for their durability and reliability. They are typically built with robust construction, making them resistant to wear and tear, and capable of enduring various environmental conditions. With a rear switch of I331 flashlight, the operation of the flashlight is often straightforward and easy to grasp. A simple press or click of the rear switch turns the flashlight on or off, eliminating the need for complex button combinations or multi-step processes.
520 lm can provide a decent amount of brightness and be suitable for many everyday tasks, it may not be sufficient for certain scenarios or individuals with specific requirements. With 2500 cd, the I331 flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances. The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output. It quantifies the concentration of light emitted by the flashlight in relation to the total amount of light produced.
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. Strobe mode on I331 flashlight produces a rapid, repeated flashing of light. It can be used for signaling purposes, self-defense, or attracting attention in emergency situations.

|Battery||1 x 14500 Li-Ion battery|
The I331 flashlight utilizes 1 x 14500 Li-Ion battery as its power source. The I331 has a battery indicator. A battery indicator is a feature that provides information about the remaining power level of the flashlight's battery. It helps users monitor the battery status and estimate how much runtime they have left before the battery needs to be recharged or replaced. The USB charger port on a flashlight can be particularly useful in emergency situations where access to power outlets may be limited.
LVP (Low Voltage Protection) is designed to protect the battery from being over-discharged, which can lead to reduced battery life or even permanent damage. This flashlight doesn't have built-in temperature control. Flashlights without thermal protection may rely on other design elements for heat dissipation, such as heat sinks, fins, or body materials with good thermal conductivity. The "8" in the IPx8 rating indicates the highest level of protection against water ingress.
|Package contents||14500 battery|
