I disagree that the main feature is the 300 lumens output. I primarily use mine on low and medium, I rarely use high. Low is actually pretty bright and is sufficient for looking inside PC's and printers. Medium is in case low isn't enough and high is for showing what the light can do on full for a brief period. If you need all 300 lumens for more than a few minutes then this light is not for you.
