One of the classic Thorn 2D fittings Nice find, especially NOS!

That's a decent score!

@Beta 5 and @Slyspark: Thanks yes a total classic - I also happen to have the dedicated triangle key that is required to open the diffuser

Excellent find too good to use since new lol

Thats the thing these are all becoming far too nice to use, unless indoors and low hours so they don't get worn out!

@Patrick: Yep it is far too good to use especially that the cover is prone to go yellow/brittle as I think I've seen an incandescent version do that which was at my last school I went to @Beta 5: Fun fact, it nearly got used for my office room main light but luckily the Ring 36W fluorescent fixture has been chosen instead as I originally wanted
