Nope no experience with them on my part. I can look up
photometrics possibly on
scoop, but data would probably be before the DKZ/DSE.
DKZ/DSE GE/Thorn #39582 PS-52/4 IF, Incd. Silica Coated 1Kw. E-39
Lcl 9.1/2"/3,200°K/28,000L/750h
Assuming it's still made would be my go to lamp for a 16"
Altman scoop. How to copare it's output verses the
scoop with probably a different lamp in
photometrics isn't something I can determine. That said, the
LED probably is sufficient and is a sustainable lamp/
LED type.
Years ago in comparing fixtures, we used to rent or borrow a
fixture in comparison to. I remember the first
LED cyc light.... About as much
power or less than one of our
cyc lights lamped down to about 300w. And by far less color
rendering. That was back 15-20 years ago, but if color
rendering is good and output seems good for your space.... should be useful and a step in greening up your theater.
Don't
throw out your old scoops! For a lightning
effect.. and if still available the
ANSI DP
T & DRW and other lamps such as photo flash type studio lamps can be really useful in output with quick response.
And in saving them, you can probably re-lamp them for work lights in some form of hunnycomb
LED lamp for service and support if not general
wash also. (Such an option most likely not dimmable.)
