It has been 3 years since i bought this lamp and mounted on my bicycle and i absolutely love it the beam is strong on its highest setting it easily has 1000 lumens as manufacturer claims i had oncoming cars flashing their high beams at me when the lamp was on its highest settingit has a very nice feature that i like the on button located on the back of lamp glows in 3 different colors depending on how much power battery has left green full blue around 50 red low time to recharge battery pack is excellent holds the load great and it is long lasting on its medium setting i rode for more than 10 hours over these 3 years i recharged the pack a lot of times so far i did not notice any drop in performanceanother good thing is that they provide an extension cord i used it to mount the battery pack on my back rack neatly out of the way see attached pic now i agree with some reviewers that the provided mounting orings are weak and cause the light to droop when riding over bumps but this is a very easy problem to fix thats why i kept the 5 star rating instead of oring i used a plastic zip tie see the attached pic my light stays solid doesnt move even on very bumpy roadsone last point i bought this lamp 3 years ago for 90

now i see it goes for 70
