Tuff-spun for 650W Read Head?
 
Hi,

OK. I have a Red Head with a 650 lamp and barn doors. I still need to knock down some of that light.

Rosco sells a kit of tuff-spun, 13 different kinds, 10 x 12, for about $40.

The doors have clips. Will tuff-spun survive being 10 inches from the lamp?

Any other thoughts?

Regards,

Ty Ford

Rosco spun should have no problems with that kind of heat - I've used it in front of a 2K Blond with no dramas.

The spun will soften your light as well as knock down its intensity, if you are after less light but still with the hard edge try some metal scrims in front or a dimmer (which will change the colour)

Ty,

If you find yourself constantly needing to dim the lamp, the other approach is to simple "down lamp" it. Just because it was designed to handle a 650 there's no reason it won't work just dandy with a 500 or even lower wattage lamp.

As sensitive as today's digital cameras are, I have nearly all the lights in my Arri kits similarly down-lamped.

For what it's worth.

Hey Ty.

Glad to see you got your Redhead outfitted. I picked up some Matthews circular wire scrims that fit very nicely in the accessory holder and knock down the light without burning up.

Also, to second Bill Davis, I've also run my Redheads successfully with 400-Watt bulbs.

Ty,
All of the above posts are good suggestions. The tough-spun will be okay. Alternately, you can down-lamp or scrim it. (The advantage to scrims being they come in different guages, and come in 'half-scrims' which you can rotate to shade different areas of the light)

In a pinch, baking parchment will also work. Pick up a roll at your local grocery store. I use it more often than spun, because it's less transparent, cuts more light and softens it.

And of course, putting it on a dimmer is also an option. Though it doesn't 'soften' the quality of the light like parchment, or tough-spun will.

AHA! What's the number of the 400W lamps and where did you get them?

FDA lamps. I got them at B&H (where else?)

What did you end up using for an accessory holder, barn doors, etc.?

Tough spun is pretty old-school, there are more efficient types of diffusion out there now (I imagine that Rosco kit has many of them). All should be useable at the distance from a 650w unit as you described. For true softening, you would want a larger amount of diffusion mounted further away from the light to properly soften the source.

Doors/safety screen combo from Ianiro from a Toronto shop. They have the accessory bracket and scrims, but I didn't get any...yet.

Brian,

Wait a minute. I'm confused about the three-letter lamp codes. I have FCD bulbs now. They are 650. FDA are 400, but will they fit the Ianiro Varibeam?

Thanks,

Ty

Instead of scrims you could as well use ND gels. They cut light in defined amounts (get some ND3, ND6 and ND9). You can still add WD or tough spun when you need soft light, but sometimes a hard spot might be necessary and you won't achieve that with tough spun in front of your barn doors.

I can't find FCD lamps on the B&H website, so I can't compare them. An obsolete code perhaps? Maybe take a look at the image at B&H and see if it looks like the lamp in your light. I use FBX for the 650W, and FDA for the 400W.

What's the name of the Toronto Ianiro dealer? Do they ship to the U.S.?

Yes they do.
