The smells of a Never Used Street Light « on: October 18, 2026, 09:49:25 PM » Author: Burrito
I've recently pondered on this thought. Why do my new old stock and even some of my used street lights have a weird fresh laundry smell, and why do my HID lamps give off a bakery smell that smells super interesting (I quite like the smell lol)? When I first brought my HM1000 into my room, I got to wiring it and there was a strong smell of laundry coming from it. Is it just new transformer varnish or is it something else? My OV-25 also had this smell but not as strong.

My 1970 GE M-250A smelt like burnt dust when I first lit it, despite being mostly cleaned.

That's the same smell I smelled on my new old stock fixtures, slightly sweet smelling, and warm bread smelling too lol

Probably a bunch of formaldehyde and antifungal agents. Is it the same smell as 1940s-1970s military radio equipment has? That stuff also has a rather nice sweet smell to it, which is undoubtedly carcinogenic when huffed daily. Don't huff lanterns, kids!

No, Formaldhyde has a sour smell from what I remember, I am around it at work in the form of carpet and treated lumber.

This is a weird thing that is very much true. My mercury lamps give off a clean laundry smell after running up, too.  :mrg:

Sometimes it just takes a little bit of time and a concerted effort to learn something new. Don't give up before you get where you want to go.

I could've sworn I smelled a little ozone the first time I ran my philips MV but it never occurred again lol
What I have noticed is, even when kept far away from bugs and being thoroughly wiped, my SON-Ts produce an odor similar to burning bugs. I can't for the life of me find the source of it.

Some HID bulbs give off different smells when they're operating. MV lamps smell like bread almost when they're hot. Could that smell have been with the lamp since it was new?

Now that you mention it, yes it is! It's really mild but I absolutely do feel it even when the lamp is running, not just new. Although the ozone kinda worried me, it has disappeared since so that's fine. For the most part is just smells like hot air but happens to have a mild scent to it.

Yeah, this scent is kind of nice lol. If you smelled ozone, wouldn't the bulbs envelope have to be broken open?

That's what puzzled me so much cause it happened with a BRAND NEW intact HPL-N, and never again but I know for sure it was the same smell as with that of a germicidal fluorescent. Although I might have well been overdriving it a bit with inappropriate control gear lol
