The Profoto D1 250 w/s Monolight is a significant refinement of the ComPact monolight series from the company which having become synonymous with professional strobe lighting, is now celebrating its 40th anniversary.
No stone has been left unturned in the provision of tech and convenience features that seem to derive from professional photographers' wish lists. The sleek matte-black, high-impact polycarbonate finish encases strobe design that goes beyond the highly visible LED readout and is digital from the ground up. The 7 stop power range breaks down to 1/10 stop increments providing flexibility, precision and consistency, made possible by dual mode SMPS capacitor charging.
A new built-in 77 degree reflector (5.12" diameter) maximizes case space and is ideal for umbrella and softbox use. Features that we've come to expect from Profoto over the years: short flash duration, rapid recycling, a bright 300W modeling lamp and heavy-duty cabling are all on-board.
Modeling lamp operation is user-selectable: On/Off/Proportional and Free (manual). There is also a selectable flash confirmation (dimming) feature in addition to an audible, fully-recycled tone. The D1 is compatible with the full line of widely-acclaimed Profoto light-shaping tools. Finally, the self-sensing multi-voltage circuitry allows you to take the D1 anywhere in the world.
Note:D1 Air models require use of a Profoto Air remote or Profoto Air Sync for triggering the strobe from the camera
