Comments:This just arrived today to replace the 6ft unbranded fitting bought from a local DIY store 18 months ago, which never looked right with the Fitzgerald LP40 at the other dining end of the kitchen. The opal diffuser is to match the Fitzy. Of course these are pop packs are not a patch on the earlier models from the 70s & 80s. It does amuse me the way they try to sell the snap of cover plate as a feature that does not require tools, when it is obviously to keep manufacturing costs down. It is certainly more cumbersome than the screw on plate, there was a certain amount of language used that I cannot repeat here! Shame that it is not the switch start I had ordered, especially as it really does seem to be under driving the tube! It does look much better than before though.

What tube did this come with?
Rob_TDCi   [Mar 20, 2014 at 07:32 PM]
It came with a Dutch made Philips 840 so not all bad Very Happy

Yes they are decent tubes!

Certainly looks good! Cool

Already managed to collect a dead fly in the diffuser and it's still only very early spring! Sad

I personally dislike diffusers on fluorescent fittings for a number of reasons, one of which is the collection of dead insects! Other than that they yellow over time and also collect a surprising amount of dust. I also like to see the etch on the tubes and the banding/wear marks as the tube ages.

Think the snap on covers are difficult to fit on these? Try doing it on an 8 foot suspended on chains! :doh:

Haha I can imagine diffusers being a right fag on 8 footers lol. I wouldn't bother. I'm a big fan of the naked batten/tube look too, an old T12 PP needs to show it's beauty! But diffusers do have their places and I do have a soft spot for the opal sided prismatic jobs!

These opal Thorn diffusers remind me of when the filament lights were replaced with 8ft Thorn 100w pop packs when I first started school in 1978. They also had opal diffusers, and were a source of fascination to me, so I think that is why I like them. Flies are really stupid though, they seem very good at getting into things but can never get back out!

Nice thing about this diffuser is that the design hasn't changed much over the years so you could just make yourself believe there is a good old, solid T12 PP under there!
Tom   [Mar 29, 2014 at 01:57 AM]
I'll concur with you Paul! Best thing about the PP is the diffusers have remained practically the same since the grey sided Atlas days!
Kev   [Mar 29, 2014 at 09:43 AM]
They have! This is why before the PFI collapsed I started refurbishing old fittings with new thorn diffusers and 840 T12 tubes I did loads of 8' where the diffusers had yellowed and I remember doing a grey sided atlas brand new pris diffuser and Philips MCFE PRO 840 sadly got skipped when the PFI went down the pan

I think you had a pic of that Kev that I remember seeing. Most of my primary school building has been re-built now with only two front classrooms retained for historic reasons, but sadly the 8ft pop packs have been replaced when a drop ceiling was installed. While I can see why they have installed the ceiling, it completely ruins the character of the place. The original ceiling is high enough to build another floor into the rooms! Funny to think the old rubber wiring from the original install will still all be in situ in the loft space, but has not carried any electricity since summer 1979.
