Brand new old stock, a big heavy lump this. I think these were recently/are still made under the Venture brand, they look identical anyway.

This has '89 D' printed on it at the other and, could be a date code?

Whats the difference between the white paint/varnish and the clear varnish we use here in N. America? All European ballasts I see are painted white. Also, does anybody know why Europe and UK adopted the screw terminal blocks instead of other connection methods? Again, something thats non-existent here in the US

I don't know why they were used, but I'm glad they are. They're a far better connection method than those awful wire nuts you seem to use your side of the water. Don't know why they're white, either, although some older ones were other colours, quite often black.

I don't disapprove of LED's for domestic and other indoor use, I just don't like them for street lighting.

Yep D89 = April 1989

Re the Terminal Blocks they have been used on ballasts since the 1930's Possibly as they were chosen by the BSI (British Standards Institute) for Electrical Safety.

I have a older version of this Ballast with Ignitor and Capacitor from 1986 see [url=

I've got a few of them 40uF capacitors (BICC I think?). All well used but test out perfectly, most within a 2.5% tolerance (1uF)
