Imalent R90C (R90C) specifications

Rated 3/5 based on 1229 user votes.

The R90C flashlight offers precise and focused illumination. Unlike ambient or overhead lighting sources, flashlights allow you to direct the light exactly where you need it.


Weight1250 g
Length206 mm
Body diameter55.5 mm
Head diameter129.5 mm
Materialaluminium alloy with HAIII hard-anodized finish

This 1250 g flashlight is quite heavy for a handheld flashlight. The increased weight can provide advantages such as longer runtime, enhanced durability, and the ability to project a brighter and farther-reaching beam. The length of the R90C flashlight can affect its portability. A shorter flashlight is generally easier to carry in a pocket, bag, or pouch, making it more convenient for everyday use or when you're on the go.

The aluminium body of R90C has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery. The body of R90C flashlight treated with a Type III hard-anodized, anti-abrasive finish. The R90C flashlight is offered in a stylish black color.

Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The primary function of the smooth reflector (SMO) is to precisely focus and project the light emitted from the light source into a defined beam pattern. The smooth surface allows for greater reflectivity and light concentration, resulting in a more focused and intense beam with a longer throw distance.

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 R90C flashlight. The R90C has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.


Flux20000 lm
Intensity704900 cd
Throw1679 m
CD/LM factor35.25

The R90C flashlight with 20000 lm is an extremely high lumen output and offers an incredibly bright and powerful beam of light. The R90C is a 704900 cd flashlight. Flashlights with extremely high luminous intensity often require significant power and generate more heat due to the increased energy output. 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.


Modes7 modes
Mode memoryyes
Ramping modeno

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The R90C has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again.

Thermal regulationyes

The power source of the R90C flashlight is 4 x special 18650 Li-Ion battery pack, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

The R90C cannot charge batteries directly. You may need an external charger to keep your battery going. When the R90C flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level. The built-in thermal control automatically adjusts brightness output to prevent overheating. The "8" in the IPx8 rating indicates the highest level of protection against water ingress.


Package contents2 x spare o-rings
battery pack
wall adapter

By including a battery with the flashlight, you avoid the additional expense of purchasing a battery separately. Instead of searching for compatible O-rings or waiting for replacements to arrive, having spare O-rings readily available allows for convenient and immediate repairs or replacements.

The performance of the Imalent R90C flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
