Hi,

I bought a olb Philips 60W bulb from someone who found it in his grandparent's home.

You can see pictures attached.

Unfortunately, it doesn't have the original box and I can't see any date or number on the bulb.

How can I know hold old it's?

Thanks for your help

Best regards

Fabrice

The etch looks fairly modern. I wonder if this is a modern reproduction lamp.

Yes, Philips made carbon filament lamps until about a decade ago. So this is not likely to be that old. Still a nice lamp.

I think 60-70s
