I went to my local Lowes to check on the head lamps and I found this one that advertise to have 800 lumen, if true, it would make it nice and bright:
The unit, when fully charged, is very bright, but, I notice that as you use it the brightness slowly reduces. This would take about 1/2 before you start noticing it. Since I work on the models for usually no more than 1 hour, as soon as I stop working I put it to charge again.
The is what I have found with the unit:
It looses brightness over time
To charge it there is this door that have to be open to get to charging port and they made it difficult to open this door.
The batteries can not be remove, the instruction are very clear to the point that they advice as not to open the batteries compartment because some chemical may leak that apparently is bad for you.
The instructions indicate that you can recharge this unit 500 times, then what? I guess you have to trow it away a get a new one
The unit is comfortable. Cost was about $38
I guess I will have to continue with my search.
Will keep you posted as to what I find next.
