Q: 1. I've always wondered how the TTL in Profoto heads have any idea how much light to produce. From my understanding, the TTL information is coming from the camera's computer using light coming Through The Lens. So, that information is correct for the distance of the camera sensor to the subject. But, the camera's computer doesn't know where the Profoto head is located. If the head is the same distance to subject as the camera sensor, then it should be accurate, but if the light is further away, the result should be incorrect on the dark side, and conversely , if the head is closer to the subject, it should overexpose, all using the same TTL information.My question for speed is, at what wattage per second is the D2 achieving 1/63,000 sec (500 W/S model), or 1/50,000 sec (1000 W/S model)?With my B1's, if I need fast flash speed, I sometimes need to gang up 2-4 heads to keep my light output at a usable level. I would love it if the flash was controlled to actually cut off at the faster time, without a light tail. That technology would enable higher output while maintaining the short flash duration. If the D2 has the ability to hit a fast flash duration while at full power, I would add it to my studio immediately.

A: According to Profotos specifications for the D2, the 500 AirTTL unit has a flash duration of 1/63,000s at 1 watt/sec and while the 1000 AirTTL unit has a flash duration of 1/50,000 at 2 watts/sec. Both of these measurements are applicable when the monolights are set to freeze mode.

Q: 2. I want to purchase a spare modeling light bulb (not strobe tube) for the Profoto D2 1000 AirTTL Monolight. What exact bulb does this monolight require? Perhaps someone can send me a link to purchase the bulb? Thanks friends!- Chris

A: The Eiko DRA Lamp (300W/120V), B&H # EI64514, or the Hensel Modeling Lamp for Integra Monolights - 300 Watts/120 Volts, B&H # HEMLI, would work as a modeling lamp for use in the Profoto D2 1000Ws AirTTL Monolight.

Q: 3. Can you plug this light right into a wall?

A: Yes, it can be plugged into the wall directly.

Q: 4. To sync, can I use the radioflash from other brands or only Profoto?

A: Using the Profoto air remote would be the most useful as the D2 has a Profoto receiver built into the head. However if you wanted to use a different transmitter and receiver, you could as there is a 3.5mm sync port on the D2.

Q: 5. Can I use this moonlight to optically trigger a (slave) Canon 600EX-RT flash?

A: The Canon 600 EX-RT uses a proprietary optical signal that this unit can not control or trigger.

Q: 6. Will this work in a B1X 500Air TTL? My existing battery failed after about 10 hours of use!!! This has different Energy/capacity and Nominal/Charge voltage than the one I have.

A: Yes it will work

Q: 7. I assume this will respond to the Profoto Connect Pro remote?-- not just the one listed as "essential" here

A: Yes the Profoto Connect Remote can fire this Profoto D2 1000 Air Monolight.

Q: 8. Does this unit support charging while in use?

A: No it doe not sorry

Q: 10. What sync cable is compatible?

A: The Profoto D2 1000Ws AirTTL Monolight uses a standard 1/8" (3.5 mm) sync terminal on the monollight light fixture. The sync input is located on the bottom of the unit as pictured on page 9 of the Profoto D2 1000Ws AirTTL Monolight's included instruction manual (labeled as #14 in the image). If you are looking for a recommendation, the Profoto Sync Cable for D1 Monolight, B&H # PRSCD1, or the Impact Sync Cord Male Mini (3.5mm) to Male PC (16'), B&H # IMMMPCM16, would both be compatible for your usage needs.
