No - the metal tabs are just some scrap brackets I found, somewhat springy.
They just compress into the dimples on the ends of the bulbs to make contact
and hold the bulbs in place.  If you're asking where to get such brackets,
I'm not sure where to look for such material.  Maybe phospher-bronze stock?
