I waited patiently for this light to become available. I have been using the rear (red) light for a couple years and was beside myself when I broke it. I bought a new one right away but had to wait for a few weeks for it to arrive. In the meantime, I tried 3 or 4 others. I love my rear blitzu so much, I was very excited when I saw that they offered a front light as well. It wasn't available until late Dec 2020 but it finally arrived and I was able to use it a few times. Same as the rear, red light. with a 50% blink it is very effective for about 2.5 hours. If you are on a long ride, which I do a couple times a week in the Summer, they fizzle to dim blip in about 3.5 hours. It will stay lit for 4 but dimly. I still love the high intensity for the first few hours and have started carrying two in case I end up staying out longer than expected.
The other feature for the front light is that it doesn't take a lot of room on the handlebars. I don't know about you but my handlebars are a bit crowded so this low profile strap works better than some of the other front lights.
By the way, I don't use this light to see the road at night... I use it for visibility, so cars only go after me if they want to... not be accident.
