Hey strobists–game over now. Today, Profoto is announcing a jaw dropping new product in the lighting world. Meet the Profoto B1 Air TTL: a studio light and radio flash transmitter combination that that read your camera’s ISO and aperture settings and adjust the monolight accordingly–just like speedlights. It’s called the B1 500 AirTTL, and at the moment it will only work with Canon DSLRs, though the company is promising a Nikon version in 2014. It uses a new Air remote called the Air TTL-C, which works with your Canon DSLR’s metering system and can allow you to manually control the light or use TTL.

The remote will be sold separately from the light so you can use it if you want to. Considering that this B1 is 500 watt seconds, you know that it will be packing more power than five speedlights. The light can be controlled in tenths of stops over a 9 stop power range. It also sports a quick burst feature to let a photographer fire 20 bursts if they want.

Tech specs are after the jump. Who knows, they could have started to make the handheld light meter obsolete. Both products are available today.
