This brightness adjustable light is great for touring the bike paths at night up to 250 lumens (so not to to blind others on approach) , then if you drop into some dark off road wooded paths you can amp this light up to 1000 lumens and literally have daylight like viewing. I like the included diffuser lens to reduce the harshness of the light and spread out the beam slightly to pick up low tree branches etc. I only wish you could not only increase the brightness, but also decrease the brightness rather then cycle up through the brightness levels to get back to the low level. I don't think I would be using any of the blinking modes.

In winter when you have cold fingers it's almost impossible to turn on light as the button requires alot of pressure and you have to hold it down for a few seconds. Even in normal conditions it's frustrating to power on.

Side note....

Light had problems and eventually stopped working and it wasn't used in wet conditions or droped or anything out of the ordinary. Would have sent it back for repairs but the return time and procedure is long and tedious.
