Compact 100Ws flash head

The Profoto A2 is a 100Ws monolight flash head roughly the size of a soda can. It targets photographers who need portable studio power for location or studio work. The unit delivers a 10-stop power range adjustable in 0.1-stop increments. Its 5800K colour temperature stays within ±100K for consistent output.

Magnetic mount and wireless control

The flash head attaches via a built-in magnetic mount for quick setup on compatible modifiers. Recycle time spans 0.1 to 1.6 seconds depending on power level. AirX wireless sync works with Profoto Air and Connect Pro remotes on any hot-shoe camera. Bluetooth enables smartphone triggering through the Profoto app.

Check power source and modifier ecosystem

The A2 runs on a dedicated Profoto rechargeable battery, so verify you have a spare or charger for extended shoots. Ensure your light-shaping tools use the Profoto magnetic mount or an adapter ring. Confirm your camera hot shoe or remote supports AirX triggering before ordering.

Questions about this item

How do I verify the flash is delivering the full 100Ws output after setup?

Fire a test shot at maximum power and check the histogram for highlight clipping; consistent 5800K colour temperature and a 1/26,000 sec flash duration confirm the head is performing to specification.

What comes in the box and what must I purchase separately to trigger it wirelessly?

The monolight head ships with its built-in AirX receiver and Bluetooth; a Profoto Air or Connect Pro remote for camera hot-shoe triggering is sold separately.

Which power setting should I choose for freezing fast motion versus balancing ambient light?

Use the shortest 1/26,000 sec flash duration at lower power to freeze action; increase output up to 100Ws across the 10-stop range in 1/10-stop steps when you need more light for ambient balance.
