PHILIPS HPL 125W

PHILIPS HPL 125W

Click to view full size image

This one came with the old French Philips NVF 125W lantern. I think it is the original bulb which was used in the lantern. The bulb has seen high hours because the burner is pitch black. The lamp base is somewhat bent as the fixture may have got hit by something.

Really nice, Michael! That's indeed a lamp from the late 1950s, the cues are the dot date code and the round Philips logo, combined with an ellipsoidal bulb (earlier models had an A-shaped bulb). This HPL is coated with magnesium arsenate and has a N2-CO2 atmosphere. Looking at the stem, it seems that your lamp is made of a weather-resistant borosilicate glass. In order to reduce production costs, Philips later changed the bulb to a soft soda-lime silicate glass for its 125 W HPL(-N) lamps.

Nice old mercury lamp!

If I'm reading the date code right, it's July 1957, a lovely old lamp

Thank you guys!

Didn’t have the hard glass type the designation HG after wattage rating?
At least I’ve seen later HPL-N 125W bulbs with hard glass HG symbol on it.

Yes, our HPR125 lamps have HG on them, but it must have been a later thing as the MLU300 sunlamps we have made in the 1960's didn't have it either.
