IPF looks like it's double the cost of the Cyclops, which is insane. I haven't tried them, but there is no way they are double the light or quality. Cyclops is the only one I've found that has proven to be worth a premium over basic Amazon $60 bulbs. IPF might be just as good as Cyclops, but I can't see any reason why any LED bulb would be worth the $195 IPF wants.
