A large, early projection lamp...these are hard to find at any time, (I only have one and I had to appear on National T.V. to get it) ....Jaeger exhaust are even rarer, so finding both in one lamp is a real amazing feat. (And "Tight Round" as well, your tastes are impeccable.)

In the 1930's they applied borosilicate glass and Krypton fillings, so they could dispense with large, round bulbs like G.L.S. would normally use and make more compact tubular lamps with greater energy density for projection purposes. (As Krypton is a poorer conductor of heat and borosilicate glass has a higher softening point.)

Manufactured articles should be made to be used, not made to be sold!

thank you very much globe collector !!! Excellent information !! as always thanks for sharing the wisdom! I'm glad you appreciate these light bulbs too! I really like old Philips. But it is very difficult to find them. and I paid 50 euros for this bulb. Do you think I paid a lot for this piece? . On the base it is written 6-5-25. 1925? but I don't know if this is correct . https://www.lighting-gallery.net/gallery/displayimage.php?pid=167568&fullsize=1

Yes, Daniel, the 6th of May 1925 sounds as if it is in the correct period to have a Jaeger Exhaust. Mitchell and White exhausts (the normal stem concentric exhausts you see in common lamps) were developed in 1919 by G.E. and almost all manufacturers purchased the rights to use it immediately so they could get rid of the fragile exhaust tips on bulb crowns where they are very exposed. This new exhaust was relatively easily mechanized for "small" lamps, (<150w or so) but bigger lamps were more difficult to implement in a mechanized way and continued to be handmade well into the 1920's and in some places into the 1930's. These handmade lamps very often featured a Jaeger Exhaust as it was easier?? to hand make than a Mitchell and White.

Fifty Euros for this: I think is good value considering its age, condition, fragility, fact it is hand made. If you had to buy this new in 1925 it would cost far more than the then equivalent of fifty euros!

A question Daniel: How long have you had a passion for large incandescent lamps?

Manufactured articles should be made to be used, not made to be sold!

It really is very old. almost 100 years and it does not seem. Thanks to see your gls philips copies and your explanations. Whenever I see a jaeguer escape I buy the bulb. It's very interesting how they changed to Jaeguer. I have a 2000w philips bulb with the jaeguer tube. I have not seen any other like it. They are usually straight tubes. It is true that very old bulbs with an exhaust tip are very fragile. Then it was worth paying 50 euros for this bulb! I'm very happy .
My first bulb has been a 200w ge specimen. which is considered a giant specimen! but ... once I worked in a very old place and these copies were hung. They are my first 500w bulbs! which are the ones that made me very excited. I show you the link so you can see my first 500w bulbs. Spanish manufacturing. Mazda metal. Spanish factory abandoned in the 80s!. https://www.lighting-gallery.net/gallery/displayimage.php?album=search&cat=0&pos=1&pid=151275
