Well lets ponder this logically, If Mars 4 uses a ultrabright 1 watt bulb and the Cateye uses bulbs less then 1 watt total how is that going to be brighter then 1 watt? And neither would be brighter then 2 watts, so why spend the money for either if the Cygolite is the brightest of the 3?
It would be interesting to see a You Tube video on the Cateye and compare it with the Mars 4 but so far it's not available.
