Just looking at another thread reminded me that all the street lights in the UK use something similar to an ORP12 cadmium sulphide light sensor. What are they going to replace all those with?
I'm preparing to file an application for exemption - I may very well need cross-EU support for the cause...Jakob E.

Probably a photodiode or phototransistor that costs about 10 cents more. These cadmium-whatever sensors are real inconsistent from unit to unit, but there's a really big difference in light between daylight and night, which in this application only means some street lights will come on a few minutes before others.
Just call it public safety and you have the same exception the police or military have.And trains and airplanes ...
LDRs are painted over and then calibrated by scraping off the paint.
You could always inform your local standards body that Harman is possibly importing products that violate ROHS. Should be fun!CheersIan
Make that Samsung...
Have Harman been bought by Samsung?
Yes, Fender vibrato opto's are out as well...
> what if... selling an "opto" compressor with no cell installed, but with a socket for it, and including a free CdS opto cell. ...No rules are broken.What if... selling an opium pipe with no opium in it, and including a free hit of opium. The user could easily install it and voila. No rules are broken? I do not know if CdS is subject to the same stringent laws as opium is in many countries. But it seems unlikely to pass muster with a judge.
