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.

You're blinding car drivers even when you're running it at medium and moving the beam downwards. There's a reason why car headlights use reflectors for light distribution and beam shaping.
A good bicycle light with even 1500lm is this:

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.

This morning I was very surprised when a vehicle cut me off, forcing me to grab two handfuls of brakes. This was the first instance since I installed my Stupid Bright headlamp.
When I stopped later I discovered why that happened. I had unplugged / removed my battery pack for recharging, but forgot to plug it back in after installation, so no blinky.
My ongoing opinion is that usage of a bright blinking headlight is a big plus for road safety.

The bicycle was being operated during daytime on the straight, level, very low traffic secondary road. A vehicle arrived at an intersection ahead of me where they had a stop sign (I had no stop sign), it almost stopped, applied the gas, then brakes, screeching to a stop. If they didn't stop I would have needed to grab two fists full of brakes or we would have collided. We might have had a collision regardless.
Bright blinky again saved the day...
