P4XX 400ws Action Power Pack

Action Packs are designed to have an extremely fast flash duration. They freeze fast moving action better than any other brand of high power flash system because they have a faster t0.1 time till the flash duration is finished. The 400ws Action Pack has its fastest setting at its highest power, so 400ws is finished in 1/1500 second. It also has settings at 200ws and 100ws but they are slower. The Pack has a seven light battery gauge and powers one Lumedyne Flash Head (Quartz Flashtube recommended) and it does give you the option of fast or extra fast recycling between flashes.

The Action Packs are special because they generate much higher voltage to gain a much faster flash duration as they go up in power.  They do have three power settings and the P4XX can be set at 100ws, 200ws or 400ws.  Because of the special design, the 100ws setting is not as fast as the 200ws setting which is not as fast as the 400ws setting.  At full power, the t0.1 time of the 400ws flash is a remarkable 1/1500 second which is about six times faster than normal flashes at a similar power level.  The slowest setting at 100ws is about 1/750 second and 200ws is half way between them.

The Action Packs are fully compatible with all generations and styles of Lumedyne Batteries and their appropriate Chargers.  The seven light battery gauge on the front of the Action Pack is best suited for the NiCd and MiMh batteries while the gauge on the front of the LiFePo4 Batteries is more accurate for those cells.

The Action Packs only work with Lumedyne brand Flash Heads (not Quantum™ X flashes) and we recommend the Quartz Flashtubes because of the high duty cycle of the special high voltage flashes.  Any of the Lumedyne Heads can work with the Action Packs but do not attempt to use the Classic AC supplies, Boosters, High Speed Modules or the Auto Control Modules with these Packs.  The modern XPSU and XACU Power supplies can add AC power options to this Pack.

The 400ws Action Pack is the selected for fast flash duration along with plenty of flash power (especially when combined with an aftermarket telephoto reflector (like from Norman or Quantum)).  When you fire this flash at full power, you can really hear the difference between this and a normal flash.  However, with regards to light output, its about the same amount of light as the normal 400ws, just faster, and that shifts the color temperature about 300 degrees Kelvin more blue than daylight, so it is advised to use the “flash” color temperature settings on your camera.

AFSQ 2400ws Quartz Flashtube for Standard non-modeling Flash Heads

AFSQ
AFSQ 2400ws Quartz Flashtubes fit all of the standard Flash Heads such as the Classic #001 and #002 Heads that had no modeling light feature. They also fit the new Extra Small Basic Heads HSBC or HSBQ. This is a super duty flashtube for high power or Action Packs' fast flash duration. The Flashtubes push/pull straight in/out and they will last for tens of thousands of flashes or one face down fall onto a hard surface. Any of the Heads that have a modeling light would use the AFTE instead of this one.

ATTE Flashtube Extender

ATTE
The ATTE goes into a Flash Head where the Flashtube normally goes and adds about an inch to the position of the Flashtube from the face of the Head. This is generally preferred when you need a different coverage from a custom reflector than the tube provides from it's normal location.
