Yup, and not just only that, but I got carry away with my helmet setup.
Here is a picture of my mountain biking helmet setup. I also use this helmet without the Olympia light up front when I commute. With both lights on, I get easily over 2000 plus out the front lumens and believe me, cars do notice. However not something I would recommend because anything from 300 to 1000 lumens on the helmet should work just fine
