As the owner of a different brand bike light and many LED lights, I find this light to be a far cry from 4000 lumens. It's definitely less bright than the low lumen Sahara Sailor brand that I also own. This observation is also consistent with the small size of each of the three light emitting diodes (LEDs). However, I cannot claim that the device I received is exactly the same as any other device of the same make and model. Products may vary within manufacturing limits, and sometimes manufacturers change suppliers or designs without changing model numbers. The light this device emits can be enough on quiet roads, dry roads and slow driving. I wouldn't recommend this bike's light output for weird trails, dark rainy nights, heavy traffic or dark pavement.
