Here you see a unusual Philips HPL-N 125w Mercury Vapour Lamp, This Lamp is indeed a strange Lamp it looks like a 125 watt Pearl Elliptical MB/U lamp with a Etched Band around the outside of the Bulb, possibly to diffuse the light in a Refractor Fitting.

The Wrapper says HPL-N but is more of the HP or MB/U Mercury Lamp

At first glance, it looked like a leaking SON (HPS) lamp...I've had some Philips lamps do this.

I have never been able to figure out what these were for. It was clearly something made in small quantities because the bulbs are inside frosted, but the etches applied by Philips say HPL-N whereas there is no phosphor, so just type HP. The run must have been so small that it did not justify changing the etch. They are also unusual in that they use hardglass bulbs whereas the 125W is more normally made in soft glass. This is perhaps because hardglass has better UV transmission.

The frosting on the outside is also most peculiar. The cheapest and easiest way to frost such a lamp is over its whole surface, but here it has been done selectively over a small area which is quite difficult to set up. I cannot think what application would require the frosting to be so locally applied over only part of the area. One day I hope someone will recognise these and know the reason and application for this most unusual design.
