Janhavi Asthana Posted February 22, 2020 Share Posted February 22, 2020 I'm an amateur gaffer and I'm working on a project that's to be shot in a house in czech republic which usually has 220v power outlets. This house has two circuits. Would it be possible for me to light the house with these lights if I manage it on two different circuits without it tripping? We do have an option of a generator but it's going to be an issue for sound as well as the building we're shooting in and we can't afford a silent one since it's a student film. Really looking forward for some help. Thankyou!!! Link to comment Share on other sites More sharing options...
Phil Connolly Posted February 22, 2020 Share Posted February 22, 2020 If you have 2 x 13amp circuits running at 230v - then you have access to 2990 watts per circuit. So that would be fine if you put each HMI on each circuit and maybe you could perhaps squeeze 1 or 2 small LED fixtures on each circuit as well. The smallest skypanel is about 200W and the larger ones, more - so that starts to get close to the rated wattage. You need to check the ratings. You might have a bit more flexibility if you had 1 x 2.5kw HMI and 1 x 1.2kw HMI - giving more headroom to drive your LED fixtures. Running 2 x 2.5kw HMI's might be overkill for smaller locations.

Thank you so much for your reply! I was planning to bounce the two 2.5Ks on a mirror reflector, which then travels through the window which has a full frost on it. Since we're shooting wide frames on really small apertures like 8 and 11 during day time, I was thinking maybe we'll need this intensity of light. A 2.5kw and a 1.2kw may work in this situation, I will consider that, thankyou!! But do you think it'll be able to give us an output for those f stops? There's also an option to get two M18s. I'm attaching the picture of the location so you get an idea of the space I'm talking about. Thankyou again! Link to comment Share on other sites More sharing options...
Phil Connolly Posted February 23, 2020 Share Posted February 23, 2020 The M18s might be a better choice. But in terms of light levels, it really depends on what looks your going for and what shooting format your using. There is a big difference between a 2000 ISO FS7 vs 200T neg Also the position of the sun could be a help For instance the below image was lit with 1 x 1.2kw HMI augmenting day-light through the window, with a couple of rotolights providing soft fill. Shot on an FS7 rated at 1600 ISO Link to comment Share on other sites More sharing options...
