Both Philips hue and LIFX have enough latency and required spacing for commands that a "strobe light" effect isn't available in the official API. The philips bridge however unofficially allows you to push "point symbol" effects to bulbs that you can later activate to get rapid changes in the bulb state, from simple strobing to color flashes. It would nice to at least get some API to initiate a strobe for X seconds, or in a dream world, the ability to assign a raw pointsymbol sequence for custom effects.
