Ohhhh I see the original 50W arrowslim? SRS or SS version! I actually think the SS is rarer in the 50W than the SS!

Ps I bet that T12 was a right bitch to get in that modern arrowslim lol

Kev you know the biz. The Arrowslim is the common or garden SRS (I've never seen a SS) and I had to unclip the starter holders and stuff the starters inside the 15 Watters so I could get the tubes in.

I wonder what fittings would of taken the 15W T12 or weather they were just designed to go in open terry clip style fittings?

Good point. I've never seen a 15W fitting that's designed to accept T12, so I reckon the terry clip + remote ballast set-up would have been the intended use.

Only ever seen 15W T12 in road signs, but i am the proud owner of a AS50 Switch start.

U need to upload it Oliver

You seen it on ATL Kev

Is there any T12 desk lamps there? There plenty of 15 watt fitting in US that Accepts T12. 15 watt T12 is just as common as 15 watt T8, infact most stores stock both lamps. I also gave Dez a 15 watt SS Lithonia strip light fitting take 15 watt T12.

The 15w fluorescent desk lamps always seemed much more popular in the US than they ever were in the UK. I have a lovely one from the 1960s which apart from some yellowing to the plastic shade is in perfect condition.

I never saw T12 15W in use in my 52 years. It was T8 or nothing, which is why T12s seem so rare and covetable here.
