The 167 g flashlight is generally comfortable to hold for extended periods and easy to carry in pockets or bags. They are suitable for various applications such as camping, hiking, or emergency situations. A 120-gram flashlight strikes a good balance between functionality, convenience, and weight. The length of a flashlight can affect how it feels in your hand and how you can grip and maneuver it. A longer flashlight may provide a more substantial grip, making it easier to hold and control, especially if you have larger hands.

The aluminium bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Anodizing enhances the corrosion resistance, hardness, and scratch resistance of the aluminum, while also allowing for a variety of attractive finishes. The HAIII coating often has a matte or textured finish, which enhances grip and provides a comfortable feel in the hand. This can be particularly useful in situations where a secure grip on the flashlight is essential, such as in wet or slippery conditions. This flashlight features a captivating black color.

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. The SRT6i uses a smooth reflector. Unlike the textured surface of an orange peel reflector, a smooth reflector has a polished, mirror-like surface.

The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The SRT6i uses multiple switches. Depending on the placement and design of the switches, a multiple switch configuration can allow for one-handed operation. This is particularly helpful in situations where you need to hold or manipulate objects with one hand while using the flashlight with the other hand.

The SRT6i has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness. With a rear switch of SRT6i 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.

Performance

Flux2100 lm
Intensity65200 cd
Throw511 m
CD/LM factor31.05

The 2100 lm output of SRT6i provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. With 65200 cd, the flashlight will provide an intense and powerful beam of light that can illuminate objects or areas with exceptional brightness and clarity. The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 0.25 lux. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.

The SRT6i flashlight utilizes 1 x 21700 Li-Ion battery as its power source. The SRT6i 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. USB rechargeable flashlights have become increasingly popular in recent years due to their convenience and sustainability.

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. The SRT6i has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. This feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety.

The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the SRT6i flashlight, is fully protected against the entry of dust and other solid objects. The SRT6i flashlight with IP68 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer. It is important to consider the impact resistance rating when selecting a flashlight, especially if you anticipate using it in situations where accidental drops or impacts are likely to occur. Auxiliary LEDs with different color options or specialized modes can be beneficial for specific tasks.
