The link you shown is not a T-6.
T-6 has a 20mm diameter tube and it does not need a plastic adoptor to fit in the standard light socket.
These lamps are a T-5 modify with a adoptor to fit in to standard light socket. They have similar performance like the t-5 but does not work as good as the t-5s. And will requier electronic ballast to work. They do not or don't work well with magnetic ballast.
I have these lamps too and they are Cheap. You can fine these lamps from most Chiese importer for 1/2 the price (or less) of a good T-5s.
The T-6 we have been talking about have no relation to the lamps in the link you shown.
Sorry to disapoint you.
