I have a small terrarium which is currently illuminated with linear flourescent lights. I want to change these lights to compact flourescents but in order to do so I need a couple of 90° lampholders, prefereably Edison Screw (ES). This is to enable the lamp to be parallel with the terrarium lid. I have searched around and the only ones I can find are Ceramic lamp holder and bracket, designed for vivarium use. Whilst these would do the job adequately, they are approximately £14 each and I'm looking for a cheaper solution. Does anyone know of a cheaper source of such a fitting? Ideally the holder would need to be touch-proof, though if it was not then I'm sure that I could make it so.
