It should be decent, with 1,200 lumens. The high beam seems to throw out well. Here is a review:

Ravemen PR1200 blasts out the lumens - intelligently - BikeRadar USA

You can Google images too...there is 4-5 that I saw. I do not own this light but have been following its development for the past 6 months or so. For mountain biking, I have always used a Lupine Betty (two versions) and they are bright and wide but I'd blind people on the road...one around 2100 and the other around 3000 lumens. I also use a Lupine on the helmet but it is only 800ish lumens.

I'd get the Ravemen for the road but 1200 lumens may not suit me on singletrack here because our trails are steep and twisty so I need wide bright lights plus on on my helmet.
