It may come to many people as a bit of a shock, but items sold on the internet are not always "kosher". This is especially true with LED Lamps, there are many and widespread, but the main warning is, are they tested and accepted by British Standards. Buying lamps from your local wholesaler and retailer protects you and confirms a minimum two year guarantee, as long as the lamp has been used for its purpose. I have tried many lamps, including those on the internet, but the best performing lamp of all of them is Enlite range. Perfect product and right price.
