This is a T12 circline lamp. I think Israel already banned these lamps, as well as the regular T12 lamps, as in ACE Buy & Build (Today "ACE") shop (I think this is the Israelis version of the ACE Hardware is the US) i don't saw T12 circlines. Only T9 circlines (Lamps themselves) and T5 circlines (Within fixtures only)
Yes they are still allowed, but there is currently no double envelope screwbase energy saving halogen lamps for sale in Israel. When they existed, a halogena like halogen bulbs was much more expensive then the electronic ballasted CFLs despite their much lower efficiency!
Also, back to the T9 circlines, which buffer gas T9 circlines filled? Argon like T12 and miniature T5 or Argon-Krypton mixture like modern T8 and T5?
Yes the Lamp is almost Perfectly Round...the Plastic Piece which has the electrical connections to the electrodes is not Perfectly formed..its just a little more straight that it should be..should be a bit more curved.
