Having ordered some lamps from your website(160mercury blended) the order was accepted, only to be told later these were obsolete. Fair enough. So I looked for others which were not what I wanted but I could make do. I then saw250watt self ballasted lamps which were shown as in stock so I put in my order.Today I am told these are out of stock and I will be informed when they are available then that these are also obsolete. I realise this is not your doing but I am disappointed you are, sorry were, advertising these lamps for sale when this clearly was not so. What's more I have purchased an adaptor on the strength of this. R T Bean.
