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

I never tire of seeing these switch on. Pretty!

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...
joe_347V   [Jun 30, 2013 at 04:53 AM]
I think this lamp is used but as you can see still has a lot of life left in it.
GEsoftwhite100watts   [Jun 30, 2013 at 01:39 PM]
Again, another one that could outlive you, even in dusk-to-dawn use every night!
joe_347V   [Jun 30, 2013 at 05:01 PM]
It will outlive you since I rarely run it..............
GEsoftwhite100watts   [Jul 01, 2013 at 03:25 AM]
In that case it will outlive both of us combined and then some!
joe_347V   [Jul 01, 2013 at 05:09 AM]
And it was used to begin with too. Razz I have a identical one that I found NOS at a hardware store though.
mercuryvaporrocks   [Jul 01, 2013 at 12:50 PM]
I've seen BT-28 lamps last for at least 20 years or so.
GEsoftwhite100watts   [Jul 01, 2013 at 04:15 PM]
You found another one too? Sweet!
joe_347V   [Jul 01, 2013 at 04:50 PM]
Well, I actually got the NOS one before (in fact it was my 3rd mercury lamp Shocked ) but I've only run it a few times. This one was a Restore find but it's probably only slightly used.
GEsoftwhite100watts   [Jul 01, 2013 at 04:55 PM]
Yeah looks like the arc tube is still pretty clear...
So you bought another merc lamp huh? What size/phosphor?
joe_347V   [Jul 01, 2013 at 05:19 PM]
That would ruin the surprise, you'll have to wait till it arrives. Razz
GEsoftwhite100watts   [Jul 01, 2013 at 05:25 PM]
Ahh okay... Laughing
joe_347V   [Jul 01, 2013 at 10:26 PM]
