I have the 8-mode MTE P7 light. The 1Hz strobe is too slow for cycling use. The 3Hz is great. The rapid strobe, which is too fast to count, is seizure inducing.

The MTE P7 has a rather diffused beam. I have it mounted to the bars, on the 3Hz setting.
At night, I have a second Q5 light mounted on my helmet. I use its very concentrated beam to light up distant objects.
