Thanks, I've always liked how cleartops looked when firing up.

Pretty pic! You should use this as your next profile pic...or the one of the 400w clear BT28 Bonusline lit on the proper ballast...

I think this lamp is used but as you can see still has a lot of life left in it.

Again, another one that could outlive you, even in dusk-to-dawn use every night!

It will outlive you since I rarely run it..............

In that case it will outlive both of us combined and then some!

And it was used to begin with too.
I have a identical one that I found NOS at a hardware store though.

I've seen BT-28 lamps last for at least 20 years or so.

You found another one too? Sweet!

Well, I actually got the NOS one before (in fact it was my 3rd mercury lamp
) but I've only run it a few times. This one was a Restore find but it's probably only slightly used.

Yeah looks like the arc tube is still pretty clear...
So you bought another merc lamp huh? What size/phosphor?

That would ruin the surprise, you'll have to wait till it arrives.
