After the first ride with the Cree lights, we concluded:
1 – if I could only run one of these lights, I’d go for the single Cree XML T6.
2 – if I’m going to do a spin, I will mount the SolarStorm on the bike, to give a good spread, and put the Cree XML T6 on my helmet to light up exactly where I’m looking.
