I think they were more designed for factory high bays weren’t they

I remember Al on LG showing a photo of a simple 3 lantern post on a busy corner in Australia, the lanterns were simple cylinders, (to cover the neck of the lamps), with an open bottom for the light! His photo showed 3, 250 MBFRs, and I thought what a brilliant idea given how much light the MBFRs distribute!

I bet that looks grim! (Not a fan of MBFR light quality )

It is not used fr street lighting because the light distribution needed is way far off from "uniform around the lamp in all directions". They did have a similar concept in East Germany (Topf lantern by VEB LBL). The lamps it was supposed to work with were not the "proper" MBFR shape but ordinary elliptical 125 mercs half coated on the neck half and just thin phosphor on the dome

TBH these are not a bad colour for mercury lamps, they show the colours of everything in my Xbox cove quite well, not bad considering the tube is visible also to some extent? I can see how the higher wattage ones were perfect for factory lighting. Interesting about ‘the pot’ Ash, wasn’t aware they were originally made for MBFR type lamps?

Our eyes and brain can extrapolate colors to a huge extent, as long as we perceive the reference light spectrum correctly for what it is. Try it even with SON (full mercury content type, fully warmed up). The intended lamps were this particular type of MBFR from Narva, but apparently never got to be widespread because screwed eastern bloc economics, so the lanterns were lamped with plain ordinary mercs all along

This is miles better than halogen and LED IMO

Oh yes , sadly I can’t use this at the moment due to my bedroom already being a frigin oven this week!, you would be surprised how much more HID gear and lamps add to this! Don’t want Tigerlilly, (my cat) getting too cooked in here during these hot nights!
