Joe. Profoto used to make a projection spotlight unit that had a projection lens on it and had a stage where masking tools and a slide holder piece would go. Similar to the Dedo in effect but much larger. It was probably 8" sq and 24" long. Great for detail lighting or projection of images via flash.
Thanks Brent. However, I am aware of that unit and have used it on shoots. Actually I used it for the wallet images on my site.
I find it to be very limited though compared to the Dedo-Light projection adapter.
For $400 the DL version is better made, a little thicker allowing more light to pass through, has interchangeable lenses (including a zoom lens), the gobo holder and clamp are more robust, you can buy a 18 blade iris for it, there's an adapter for filters (great for cross polarization), and I have figured out a way to mount fiber optic cables to it (with removing the front lens).
For $1100 the Profoto version has a fixed stationary lens with no filter threads, no great iris is available, and the gobo holder is kind of flimsy. Not to mention the Bowens version is exactly the same (minus the mount) for half the price, so it is drastically over priced.
I just need to have a custom holder made for it that will mount to a Profoto head. Too busy to find the time though, which is a good problem I guess.
