Lead solder is still available to buy and use, especially for your own occasional use. The hazzard is not with the product made using lead solder (apart from end of life disposal) it is dangers in using it for the production line solderer due to long term exposure to contact and fumes. That is why the EU is restricting its use in RoHS regs, but the cat is out of the bag with lead, there is so much in the environment from leaded petrol use over decades that solder contamination is minor compared with what is in the vegetables we eat that has been taken up from the soil they are grown in. Lead poisoning is only a real problem for children as development of nervous system and brain function is impaired. Lead only very very rarely kills as you have to ingest a lot and the effects are chronic long term. Cadmium is different and far more toxic. But the EU permit the use of this dangerous substance at amounts not exceeding 100ppm. It is not completely prohibited. And they permit its use at higher concentrations in specific exemptions. Under ROHS2 there is a permanent exclusion for photovoltaic cells (and other categories). So cadmium is a dangerous substance, with all the toxicity effects you describe, but not SO dangerous that its use is outright prohibited. Scaremongering by impying an active real possible risk to health from the use of these devices just deflects away from the valid and relevant point about legality. What information do you have about actual reported damage to health in the EU from LDR's or any other device containing cadmium? The metal is present (for inhalation) in tobacco smoke, which is by far the greatest actual source of cadmium that a typical member of the population is likely to encounter. Illegal - Yes. Dangerous potentially - yes. But not dangerous merely from its presence in devices like LDR's as an actual real threat to health. With illegal you are on safe ground. More bollocks. I said it was illegal I was asked to explain, when I said it was due to toxicity I was asked to explain - I did. I am doing as requested, where as you are pedant with a verbosity problem. It doesn't matter what you or anyone says *THE USE OF LDRs IN AUDIO IN THE UK IS ILLEGAL*

As I understand things, LDRs have many other uses.
Would any of there other devices using LDRs be illegal in the UK as well ?

Why should I (or anyone else) do the work for you. I have provided links, go and read them.

I agree - illegal. I said that in the last line of my post. you need to learn to take "yes" for an answer

I am fed up with ploughing through the rest of the nonsense to get to it.

I've always liked these. Quality British engineering that seems somewhat absent nowadays.

They look well engineered.
Any details ?

My guess would be wirewound rheostats.

It seems the seller of the LDR pre amp I'm hoping to try at home has got dispensation to sell it in the UK.

OK Shouty ....Have you ever stopped for a nano sec to asked yer self or better still ask the seller where he got his (Special dispensation to sell LDR'S) from - If so care to share it with us. Moderated No need to use nick names to cause offense

I have seen a copy of the documents, but I'm not going to post them on here.

Well that aint very nice of you and perhaps a tad selfish **** as im sure we would all love a look at these (Special Documents). If you aint willing to post em here on TAS could you let us know where you are going to post em.....!!! Ta.
MODERATION: no name calling please.

Either you are being bullshitted or you are bullshitting us, I really do not care. The law is the law the only way to get dispensation is to apply to the EU commission and they will agree a waiver which is then put into law. This happened with solar energy panels and the waiver is there on line for all to see and it has a time limit and cut off date. If this had been given to LDR's then the information would be on-line for it. A letter from anyone creates no legal waiver.
So publish your document so we can all have a good laugh.

In essence the exemption is granted because there is no ROHS equivilent for the LDR in this product.

We started of talking about potentiometers and inevitably those who insist on justifying the use of cadmium in LDRs have turned this argument around in another direction. Fact is as Richard says it is illegal whether you think EU are acting like interfering twats or not. The fact it is legal in other uses is irrelevant. So is the legality of lead solder for that matter. Nobody is suggesting that handling sealed components containing cadmium will cause instant death or harm - it's the law that counts.
Again certain people just determined to carry on a circular argument even though they have proof they are wrong. Yet again we get annoying big writing just to wind people up. Would think persistence in using bloody big writing deserves 25% bar at least.

Then there has to be an exemption in the law applied for as happened with Marshall guitar amps who led a pro industry consortium to apply for it. That exemption ran out in December last year and hasn't been renewed by the EU.
That letter has been talked about on AoS but it gives no freedom, it is purely the opinion of an official. Basically it is a nod to say we will not prosecute or pursue you, but it is no waiver under the law and if there is a problem as we have already discussed earlier then the full weight of the law will be on YOU!
There are other officials who will give you the opposite opinion basically because the EU doesn't know its arse from its elbow. All of these things will go to court if the shit should ever reach the fan, if you wish to take that chance and believe the bullshit then on your head be it, cause that is where the responsibility will lie.
