Art823_Profoto Pro-B3 750w

Description

The Profoto Pro-B3 is a battery flash delivering 750 Ws over an 11 f-stop range from 0.8 Ws to full power in tenths of a stop, with no mains, cable or generator required. Three flash modes change what the light does: Eco recycles from 0.01 to 2.0 seconds and runs cooler for long days, Boost gives full power on demand at 0.01 to 2.3 seconds, and Freeze shortens the flash to 1/75,000 s (t0.5), the shortest in its category, which separates a splash into droplets and holds the edge of moving fabric. Colour temperature holds at 6300 K plus or minus 100 K in Eco for consistency across a sequence. The Li-Ion battery gives around 250 full-power flashes or 60 minutes of continuous LED and can be charged while in use. The modelling light is a 56 W LED with up to 6,300 lumens, usable on location rather than only in a dark studio. The quartz flash tubes are user-replaceable, so a tube can be changed on set instead of the head going out of service. Beam angle is 65 degrees with an f-stop of 22.6 at two metres at ISO 100 bare, rising to 45.4 with a Magnum reflector. Triggering is over AirX with TTL and HSS to 300 m, and the head takes the full Profoto modifier range.
