I would not try and run the light off a dynamo hub .... it's been designed to run off a powerbank .... I have a much more powerful one (32 000 'chinese' cree, and trust me, it is very bright (as bright as a Volvo bus headlamp on the low setting) ...
...
mine is the one that you have the seperate battery pack. I,ve been using it for 3 winters so far, and the lamp is brilliant, but the battery pack is crap (it lasts approx 5 months, then I buy another for £10. I leave home at 05h00 and get home at 19h30 .... I use the light for approx 80 minutes a day, 6 days a week and charge the battery pack every 3rd day
these new ones that connect to a powerbank look very interesting and I buy, and I when I do long Audax, I will carry a spare one .... Heck... they cost less than £10
I'm yet to find a front light that is as powerfull and as bright as these .... I want to be able to see potholes and debris when I'm cycling at 20+ miles an hour with a tailwind, and I want others to see me .... it ticks all the boxes for me
sometimes, you don't need to spend lots of cash for something that works well
This is the one I got. Single LED.

For night riding, I would prefer the asymmetrical wider pattern out of my B&M Luxos U or my AXA Luxx 70 Plus, they do not waste a lot of light above the horizon. But they are limited to dynohub power supply. If you have a big power bank and have power to spare, then a brighter light certainly won't hurt as long as you don't blind the oncoming car.
