Speaking of NR Trinewt LED. My friend bought those and I got to try them in Mexico. They are pretty bright for sure!! I only used them on the handlebar.
I can't make a good comparison with other good lights because we had none then. My buddy was using a shitty commuter light and he didn't even need it on when he was riding behind me.
What I found odd is that the power button is on the battery pack and not on the light itself. I normally put my light on the helmet and the battery pack in my camelback and if I have to reach to my back for the switch....well...:hmmm:
He didn't bought the wireless version with remote, but perhaps that is a better option. I don't know how much $$ it is, though.
