Thank you very much, it is, mystery solved! I also found a picture with correct search name (source: http://www.opticsplanet.com/lastolite-30-light-tent.html )

Also, it is made with same material as the white diffuser reflectors. I have tried to figure out what could one do with this 'hat-like thingy' but haven't been able to come up with any smart ideas.

My friend has it (my choice of words in the first post is bad, I ment 'I came across') and as idiotic I was, I didn't take a photograph of it. I am currently unable to photograph it but I will do that when I get a chance. But it looks exactly like a pointy hat turned upside-down. The case had Lastolite written in it and I tried to search their site unsuccessfully. Maybe some old model? However, the 'pointy hat thingy' had darkened marks that looked exactly like burn marks when lamps comes too close/stays too long too close to a silk (the marks where near the "mouth of the hat"), therefore I figured it must have something to do with lighting. Weird thing is, the wide side ("mouth of the hat") does not have any clips etc. with what you could attach it to somewhere or attach something to it. It is like a reflector (except instead of even, for example, silver surface, it opens up like a hat). I'm puzzled. <- super neat illustration insted of a photo

I found an elf hat-like diffuser (silk). It folds in to a small (about 35 cm) reflector case (and comes inside one) but when opened, it's approximately 1-1,5 meters long, pointy white diffuser "bag" shaped exactly like an elf's hat or christmas hat. Do you have any idea what it is used for and what it is really called?

Thank you for replies and the link! - Ella

I was wondering what kinds of striking loads do different HMIs have (1,2 kW, 2,5 kW.. and so on). I have been taught that, for instance, 4kW HMI needs a 6 kW power source because of its initial spike in drawing electricity. Can one calculate the initial strike load? I understand that older ballasts use more power when striking than new ones. Also, if one cannot calculate the initial load (for some reason or other) is there a general rule of thumb to go with?
