Interesting there doesn’t appear to be any date codes on these. Unless it is on the sides or the bottom. They’re early ones.

Looks like 2014, I believe the 14 35 next to Made in Poland above the box with the DALI logo in means week 35 of 2014.

Shame, the 1435 sounds about right 2014/15 the Arcs got the nodes and these. Afew with 21 in the same code had May 2021 handwritten on

I think they had a bad batch Pat as loads were 19/20/21 in that box must of cost them a fortune

All the others are fine

probably dried up caps or damp maybe, even dry joints

All potted so no chance of ever even seeing they sound fucked though I’ll save them for the meet

I knew before I even clicked the thumbnail that those were gonna say 'Dyna Vision' on them.

Not sure what they achieved with the conversion other than node control (no dimming on these) and the Arcs originally had no individual NEMA sockets of the two dual carriageway sections that got left Tridonic 05 mag still was mint when removed

Did you have any of these 250 rich

This surprises me a little, I was talking about these yesterday morning with Kev, just as I had mine running a daylight Osram HQI-T , for SON specified gear they seem to run halides perfectly, even clean the discharge tubes up in my case

I see these are rated 208-277v. I bet the Cosmo one that I was subjecting to the massive voltage swing is the same inside despite being labelled as being for 220-240. I've just checked and a few different cosmo ballasts that I have are actually rated for 208-277. Interesting.
