When you are going bicycle speed, I do not understand why you need a strobe light that is 3500 lumens.
A few months ago I was riding my bike over a bridge on a bike trail, bridge was about 8 feet wide. Daytime but overcast so I did not have dark sunglasses on. And suddenly some E bike rider is crossing the bridge towards me with a super bright strobe light. I almost crashed into the wire fence on the side of the bridge because that strobe was so blinding.
Well, no, the 3500 lumen is only for a short time in Turbo mode before the light automatically ramps down the brightness. The bike mode is a steady light with either stepped or stepless brightness adjustment that "stutters" a little brighter once a second to hopefully get drivers' attention. I also ramp down the brightness at red lights so I don't accidentally shine it into cars alongside and to save battery. During daylight, I put the light into "party strobe" mode slowed down to 2 Hz so it's a nice daytime blinky running light.
That's with the advanced Anduril 2 settings. You can also just ignore all that jazz and use the lights as on-off rechargeable flashlights. Check out Youtube for Sofirn and Wurkkos light reviews, though most of those don't have Anduril. For day rides, I use a very small Sofirn sc21 pro (1000 lumen max) which weighs a few ounces, and I've used for about an hour as a good headlight when the rides last into the evening. I now also carry a couple of extra spare batteries for it (rechargeable cr123) "just in case". The bigger and brighter Anduril lights are for my class 3 ebike bars or longer pedal bike night rides.
Hey, this is 2024! I just got a mini battery bike pump (a Toptrek Airgo) that is about the size and weight of a bar of soap, and can pump up a mtn bike tire about four times before it needs recharging, which could be done on the road from the aforementioned 3500 lumen (max turbo) Wurkkos TS21 light, which can act as a battery bank. (My other light between those two is a 1700 lumen max Sofirn SC31T.) On my first ride a few days ago with that pump, I got a large hole in my rear tube that the the sealant couldn't handle about 3 km from home, and am able to confirm that it does work well, at least for one 50 psi 1.5 inch road 26in tire refill.
