Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The SD03 features a smooth reflector (SMO). If long-range illumination and throw distance are the primary requirements, a flashlight with a smooth reflector may be more suitable. The SD03 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.

The 1200 lm output of SD03 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The SD03 flashlight with 22500 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required. 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. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.
