Watts into brightness
Free ride follows your power. Pedal harder for more light; ease off and watch it fade.
You are the generator.
Keep the Light On connects a Bluetooth bike trainer to Philips Hue. Start pedaling and the room lights up. More effort gives more light; ease off and it fades.
Choose Free ride or keep your power between two limits in Don't blow it. Push too hard for too long and… poof. A small, slightly ridiculous reason to get on the bike.

Features
Don't blow it
Keep your power between two limits. Stay above the ceiling for too long and the lights go out. Flip the breaker and try again.
Pick your lamps
Choose a Hue Entertainment area or create one from a room, then select the lamps that should react.
Set the feel
Adjust smoothing, low-power sputter, warning time and sound. Gentle light effects replaces flicker and blowouts with smoother changes.
Try it first
The built-in demo gives you a simulated bike and lamps. No equipment needed to see how it works.
