I`ve not seen the Stela in use yet, the only LED lanterns within a 10 mile radius of me are Holophanes Factor large, (which I like the look of), and the above mentioned SLX?
I must admit, I had never heard of CRT either, I first saw one as a Beta 5 replacement last year, it was on the end of the original, short concrete outreach arm, the SLX lantern itself is about as small and compact as GECs Z9582, and I thought it looked quite smart in situ.
However it took me the best part of about 3 hours to hunt this lantern down on the internet (having no idea who made it, or what it was called)! I found it just by trawling through hundreds upon hundreds of pictures on Google images, until I came across it.
Within the last year though, more new columns were fitted, not too far away from me, with the lantern mounted post top, I have seen them at night, but not yet got a night shot of them.
I posted the same link, and question, on another lighting site, to which it was met with universal hatred of it!!
, but I do like it.
