The Philips sgs201 was a popular lantern in the UK. They have a GRP canopy and a polycarbonate bowl.

Staines

This Philips SGS201 is in staines. It has a green Royce-Thompson photocell and it runs on a SON lamp. Sadly, it does not work and I think it is owned by Spelthorne. 
the bowl is quite clear for its age, but the canopy is not as clean as the bowl.

This double armed column with two Philips SGS201s is on hanover way in windsor, Berkshire. One of the lanterns works, but the other one doesn’t.
