Thanks Ravi, I realized after I posted that I was mixing volts and watts in my head.
Your light sounds like a huge upgrade from the 150 lumen / 50 lux Skybeamer that is stock on my Haibike.
Indeed. It will be a worthwhile upgrade, especially if you commute or go on rides in early mornings or late evenings.
You're welcome to visit Paul's office in Ashland, OR to test this out.
Paul has a small warehouse and office and you would enjoy trying out one of our bikes.
