New-old-stock 60w Atlas SLI/H linear low pressure sodium lamp from the early 1970's.
These linear sodium lamps were the first light source to achieve over 100 lumens per watt.
Always wanted one of these 60w lamps to go with the couple of 200w lamps that I have.
Big thanks to Johnny L for getting this for me!

Must be an early one as it's a 4-leaf design.

No, needs its own dedicated ballast really, not a lamp i would get and risk lighting on anything its not meant to be lit on. Closest is believed to be a european 50w SON ballast. But even still if ive not got the ballast i aint lighting it

In the US or Canada, you might try a 50w PSMH ballast and a European 4-65w fluorescent starter to get this lamp to fire up. In that case, the ignitor that comes with the 50w MH ballast should be removed or disabled and the starter should be used in place.

Say NO to ballast and bulb bans. MV, MH, HPS, and SOX forever!!!! Magnetic preheat fluorescent forever!!!!!

Desire to collect various light bulbs (especially HID), ballasts, and fixtures from around the world.
