Originally I was going to place an order with SVETILA based in Slovenia as they were better than half the price and offered very reasonable postage charges - less than many UK companies! Unfortunately, between me doing the search for a UK company and going back to order from Svetila the prices shot up to almost that of the UK distributor, fortunately to the rescue came another UK supplier. lamps2udirect.
At nearly a third less than the distributor and nearly half the 'best' price I could find elsewhere - added to this is free delivery on orders (pre-VAT) over £30 so an order was duly placed. We'll see in time if performance has suffered in keeping costs down. If the service is good, I'll add in a link as it is always worth acknowledging good service.
