I'm guessing you mean watt-seconds (Ws) rather than watts? If so, then 320 Ws per the AB800 page: http://www.paulcbuff.com/b800.php. The thing is, Ws is not a great way to compare lights, especially across brands. Ws is a measure of the energy stored in the capacitors and available to the flash tube - not a measurement of light intensity from the tube. It can be more useful to compare f-stop at a defined distance with a common modifier..... http://www.paulcbuff.com/output.php. |

Hi sir, The reason for asking you this question is that we are planning to buy a portable generator for our lights. And I need to be sure how many WATTS not W/sec an AB800 has so that we can buy the right kind of generator. thanks |

Ooops, wrong assumption on my part. :oops: The common advice is to size the generator at 1000 watts per flash that you will be running. Also make sure you are using a generator with a pure sine wave output. |

I already scouted for the supplier and they have a PURE SINEWAVE OUTPUT generator. All I need is to choose how much WATT power. |
