Anyone use these? What is the colour temp like (how close to 5600K)? Colour spikes?
Light loss compared to CTB? Fragility issues?, etc.

I've never been able to get quite the right color out of them, so I just use gels.

Lowel specializes in making great lightweight, portable stuff at the compromise of "perfect" functionality.

I have to agree, color correction gels will do what you need.

Of course gels are more precise but I would like to know what colour temperature these filters bring the light to. What colour spikes if any they produce.
Also if say they bring the light to 5000K how does the light loss compare to using a 3/4 CTB?
oes the glass become brittle ue to extended contact with heat?

As I recall it just made the light kind of greenish, more like partial correction. But since it didn't do what I needed, I gave up on them really fast and didn't bother testing them any further. I don't think the light loss was any less than what you would get the equivalent color gel.

Dichroic's convert 3200k to 5600k. You loose 50% of the light from the fixture with them but they also do not absorb light so don't get hot and will never fade. They are highly accurate in color reproduction but susceptible to breaking and hence why I suggest filters.
