These were the first fluorescent lamps which have been marketed here in Europe by Philips known as Philora TL100 with the lenght of 970mm, 25W and 100Deka Lumen.
These size was not that common. Mostly found in show cases and signs. The T12 25W tube was replaced later by the 23W T8 for energy savings. It has the same physical lenght as the 36/40W 1m which is rare as well.
Thanks for the info. I guess that it may have been some mistake to include that lamp for listing since it not really with common lamps.
There was also this other very interesting lamp called heijastinlamppu. It's standar shape incandescent lamp that is partially opaque. The top part of the lamp is clear. Idea seems to be that this lamp would be wide angle spotlight that also would shed some light for other directions aswell. There is crappy black and white picture of such lamp but otherwise I have never seen such lamp nor there is any mention about such lamp in Catalogs I have.
