tlc Posted January 21, 2015 Share Posted January 21, 2015 We are recycling some coda 4 cell cyc battens for house lighting in a studio. However I am curious as to the extra white cables that are crimped in parallel with live and neutral.Its not the main current carrying cables that go to the daisy chain outlet connections. All 4 cct seem to have a set.Without breaking down the case it is not obvious where they go. Anyone know why they are there? Link to comment Share on other sites More sharing options...
gyro_gearloose Posted January 21, 2015 Share Posted January 21, 2015 Best bet would be to open them up and have a look. While you're there take some photos so we can all see, then we'll be able to advise you further. However, thinking about how you've described it, the white cables probably go to the lamp bases. :) Link to comment Share on other sites More sharing options...

richardash1981 Posted January 21, 2015 Share Posted January 21, 2015 Are you running all four cells at once as house? I remember having to rewire some that were used that way (all 4 cells full on) because all the wiring (and the terminal block!) had toasted out.The feeling at the hire shop I was working in was that strand only really designed with having a couple of the cells lit to full power (at 500W per lamp) for long periods, not all four. Might be less of an issue for modern 400W bulbs, or if you derate (do you want 2kW of open white?). Link to comment Share on other sites More sharing options...
david.elsbury Posted January 22, 2015 Share Posted January 22, 2015 Could probably easily get away with 300w R7 lamps (we have them here at least, I assume you can get that wattage in the UK? ) Link to comment Share on other sites More sharing options...
Brian Posted January 22, 2015 Share Posted January 22, 2015 Could probably easily get away with 300w R7 lamps (we have them here at least, I assume you can get that wattage in the UK? ) Yep, 117mm R7s seem to be available as 100/200/300/400/500W parts.

tlc Posted January 23, 2015 Author Share Posted January 23, 2015 wiring them as 2 pairs one pair OW for cleaners working lights other pair gelled as a softer option for performance house lights don't intend to run all 4 at once , as others have pointed out it toasts the wiring if a 4 cells are left on full had already been thinking about dropping wattage to 300 as the rig height is low in the studio so don't need the amount of light you get with 500 watts Link to comment Share on other sites More sharing options...
