# Need help with HPS fixture.

I recently purchased a high pressure sodium lamp for my garage. It has 2 wires white and black. I already know white is neutral and black is hot. I'm trying to connect it to an old computer psu cord. It has brown, blue and green wires and a shield. I connected black on the lamp to brown on the cord, and blue on the cord to white on the lamp. Doesnt have a ground wire on the lamp fixture. I just wanted to know if I wired it correctly. Thanks in advance.

That sounds right. Brown (live) and Blue (neutral) are the normal European colours. Earth is often green/ yellow.

Why an antique sodium lamp?, what's wrong with a modern LED one? - far more efficient and reliable.

I only bought them because they were like $5 at a garage sale #### Nigel Goodwin ##### Super Moderator Most Helpful Member I only bought them because they were like$5 at a garage sale
Do they still work?, a lot are ripped out because they have died.

However, it's a false economy due to their much higher running costs and slow warm up time.

Yep, I plugged them in last night, and they all work. However, I suspect the bulbs are going bad, as they keep cycling after warm up.
