ADC2 Diffusor Cover / UV Filter - Cloudy

This is one of two diffusors that simply snap onto the silver 5" reflectors that we have made for about 45 years. This version is the more cloudy diffusor that will lose almost an f-stop as it considerably softens and diffuses the light going through it. Some UV light is absorbed as well so the light is softer and warmer than when direct from the reflector.

This is called the cloudy diffusor because you can hardly see through it.  It loses more light output than the clear diffuser but it does soften the light more with its greater diffusion.  It loses about 8 tenths of an f-stop compared to not using it at all.  However, it also spreads the light a lot more evenly over a considerably wider area.  

I do try to remind photographer that if you are using the Lumedyne Head as the primary light source outdoors and there are no walls or ceiling to bounce the light back onto your subject, then only by making the light source larger rather than more diffused will make the lighting effect "softer".  When indoors, those surfaces become reflectors and soften the lighting based on the percentage of light you bounce versus send directly at the subject.

This Diffusor Cover is the same as the cloudy or more dense version that was included with most Flash Heads when new.  They simply snap on to the front lip of the reflectors.  Because the reflectors are hand spun, it is not unusual for some to fit tighter or loser than others.

As a natural by-product of the light going through the plastic, some of the UV (blue-ish) light is absorbed, so some people prefer this diffusor for the "warming" effect of reducing the UV end of the light spectrum.  The color temperature shift is less than 150 degrees warmer on a color meter but many photographers claim that the effect is more noticeable than that.

I have often gotten a free smile by telling people that it was keeping my light fresh and I wouldn't dream of using stale light at their event.  It's not a coffee can lid, but almost.

AFTE 800ws Flashtube for Modeling Flash Heads

AFTE Flashtubes fit all of the existing Lumedyne Flash Heads with or without the modeling light feature. They also fit in the new Extra Small Heads. They can be used at low power as well but should not be used above 800ws per Head as that is the upper rating of this flashtube's performance. 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 can use this flashtube, however, the modeling lamp itself is separate and this flashtube does not convert a non-modeling Head to have that feature.
