New Circular T5 Fluorescent Tube

I saw on website that Philips n Osram have these new holder design for circular tube. Unlike the older type which got 4 pins cluster together, these new one got two pins on the outer tube and 2 pins on the inner tube. Their specs shows that it is brighter compare to the older T5 round tube.

I have search they while Jalan Besar area and none selling Philips or Osram T5 round tube. All carry Loyal brand.

But one shop behind Jalan Besar got sell these new holder tube that cost $16 for a 40W, double the price of the older type. But problem is, I can't find the holder or socket for these new tubes and none of the shop can tell me whether the ballast use for these new tubes will be the same as the ordinary one.

Anyone came across these new round tubes by Philips and Osram? Please let me know.

U can google for 2GX13 socket or tube to see the pics of these new tubes and socket.
