very interesting datasheets of sorts!
I had no idea that Polam made a 2000W mercury lamp! would be very interesting to see what such a beast looked like (I know Polam Mercury lamps tended to be based off Philips designs so I wonder if their 2Kw lamps where also?)
its also most interesting to see their largest Self ballasted lamp is rated for 450W, rather then the 500W you commonly in Europe, I wonder if those 450W Polam lamps where like the US and Japanese 450W SBMV lamps, which ran the ballasting filament at a lower temperature compared to European lamps
this gave them a much longer lamp life, but at the expense of red light output of course
