I must be coming close to having too much light. I tried running 2000 OTF lumen on my helmet and another 3000 OTF lumen on my handlebar and I keep getting cars flashing their headlights at me even when I aim my lights down.

One time I tried running my BR IV on high on my handlebar and my 3 x XML light on my helmet on 800 lumen and had a LEO on the opposite side of the street turn on his spot light and flashed right at me several times. He then realise I was a cyclist and turn it off.

My 3 x XML light on my helmet running at 800 lumens is much more blinding than my Jetbeam BC40 XML at 700 to 800 lumen. From a distant, the single xml at high power looks light a very bright single point of light while the 3 x XML looks like one big huge bright spot light although it is running about the same light output as the single XML Jetbeam BC40.
