AFSQ 2400ws Quartz Flashtube for Standard non-modeling Flash Heads
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.
The AFSQ is the high power flashtube for any of the Heads that Lumedyne has ever offered that do not have a modeling light feature. This is the recommended Flashtube for Action Packs and any heavy duty usage. It is higher power rated because the helix is Quartz glass rather than the normal Pyrex flashtubes and that makes it better able to handle more heat. It is not stronger against impact damage.
It casts a 50 degree coverage with the reflector normal and 70 degrees back in the wide angle setting. Because this is a little bit more narrow than the modeling style bulb it is also slightly brighter by about 1/3 f-stop.
This is an 2400ws rated flashtube so when you plug this into your Head, then you can comfortably shoot from 3ws to 2,400ws.
If you never flash over 800ws through one Head, then you could use the less expensive 800ws Standard Flashtube AFSE.
This will not fit into any of the Heads that have a modeling light due to the legs and bulb that would not go into this flashtube.
