I have the Dinotte XML-3. It's been independently measured at 2000 lumens. It runs 100% (2000 lumens) 50% (1000 lumens) or 25% (500 lumens).
It's a fairly wide beam, originally designed for mountain biking.

I do aim it downward, so the main pool of light on the road is about 25-50 feet ahead. But part of the beam is above level.

I run it at 2000 lumens in the city, to compete with car headlights, and alternating bright and dim areas. Even though the beam is pretty wide, I've never had a car flash it's brights at me, or otherwise react. Even 2000 lumens appears to be about half of a car headlight.

The 2000 is way too bright on dark country roads after my eyes adapt -- the reflective street signs are extremely bright. I'll only go 2000 on faster downhills.

A good bicycle light with even 1500lm is this:

Amen!

Now that bike lights are getting this powerful, awareness of this is critical. This is something we really need to encourage for all cyclist to adhere to before there's a need for legislation forcing us into some kind of legal code. The last thing cyclist need are more of the strong arm of the law interfering with our sport/recreation. Guys make sure we're not blinding anyone.

I don't know how to "encourage" people I see on the MUP to be more considerate. Sometimes I will cover my eyes with my arm as a gesturing message, but they probably don't "hear" me.
