Hi peeps,

I have an old Victorian street lamp i want to hang off a telegraph pole
in my garden. It was gas originally, but i need it to produce a decent
amount of light, be efficient and reliable.

It looks a bit like this-

But is 50cm wide and 80cm tall, i think it needs a bigger bulb!

Any suggestions?

High pressure mercury vapour lamps were a common replacement in street
lighting gas lanterns.

but are now obsolete, with sodium & HID both giving better lpw and better light quality.

HID would be good if you need an excess of light.
