In my opinion, they shouldn't even make plastic refractors that fit medium sized cobraheads. That would solve the issue right there, with the exception of 250W and 400W small sized cobraheads.
is polycarbonate really that much more vandal resistant than glass? Once the polycarbonate yellows it gets really brittle. So instead of having to replace the glass lens because of vandalis that could happen, they have to replace the polycarbonate refractor pretty much every time they relamp the fixture. Looks like this light is controlled by a switch or a relay? there's a shorting cap in the PC socket.
Ahh i see. Speaking of remotely controlled street lighting, I read a couple years ago that there's a special software that can be used with specifically designed photocells to allow street lights to be controlled with a smartphone or tablet (or a computer). I would imagine if such a system were used in a big city that someone might try to hack into the system and shut off the lights but I'm guessing this software is geared more towards parking lots and private area lighting rather than lighting on freeways and public roads. I don't see the need to be able to control lighting with a phone or tablet. photocells and switches have always worked in the past and still work fine for me lol.
