Two PL13 ... fixtures? Or whatever it is.

I finally own two lightweight, portable trays containing the necessary gear to test any 13W PL lamps! I found those with the circline adapter, and a 22" computer screen worth 300$ I repaired fmyself!

Those are now with all my other lamp testers I have. They are very convenient to test lamps, especially when you're in vacation or anytime you're away from home. You don't need to bring either a complete fixture or the separate components. You have a small lightweight device to do that, just install the lamp and plug it in!
