This headlamp can go on your hardhat or it can just go on your head. I prefer to wear mine on my head. It has 6000 lumens and is waterproof, rechargeable with a USB and has a zoom or flood lamp mode. This is light weight also, and the band is stretchy and really isn't uncomfortable to wear without a hard hat. I love using this for working on my car, under the hood where it is hard to see what I am doing. This makes it so easy! and if I don't want to wear it, I can hang it and have the light. I use it for a lot of things besides the car, it is one of the handiest tools in my box!
