This is a recent addition and after giving it a clean it has turned out quite well. It has the original mica "glass" which makes it the /2 option. Other than that it is pretty straight forward with what you see is what it is. It is marked Y 30. I havn't got around to lighting it yet as it is daylight until very late here at this time of year. I can't see any reason why it shouldn't work well though.
