Thorn Arrowslim with Osram 830 38W

Picked this up off of ebay for about a fiver inc PnP.
From the picture i'd say the bloke was doing work on a house and just selling bits.
Really good fitting, ran it for 24hr to see how it lasted and it works fine.
Never owned or seen much of arrowslims so thought i'd get one.
I got 2 38W Osram tubes and they run fine now.
First time I powered them the mercury had not gotten to the middle and it was a dim purple!
Will get picture of the whole fitting once I have room.
