Polamp LRF 125w MV Lamp

Polamp LRF 125w MV Lamp

This is my first Polish lamp and it is a noticeably heavy lamp compared to most 125w MV lamps.
When fully run up this lamp gives off a greenish tint with very little red output despite being new and unused which I suspect is down to the type of phosphor used. The CRI appears to be quite low from what I can tell.
The lamp is branded Polamp but the packaging is just marked Polam.

If anyone could tell me what phosphor chemistry this lamp uses I'd be very interested to know. Thanks :)

The lamp's fluorescent coating consists of a mixture of tin-activated zinc calcium orthophosphate (orange) and europium-activated yttrium vanadate (red). The color quality of the emitted light is indeed inferior to that of standard fluorescent HPMV lamps because the red output from this LRF is quite low.

Thanks Max!

My main area of interest is vintage fluorescent and mercury lamps. Always interested in doing lamp trades - just let me know!
