The bulbs appear to be excellent quality and are much better than the 9w leds we had previously. A better spread of light, no shadowy areas, and they are just as bright. As good as the original GU10s we had a few years ago, with a fraction of the wattage. The only criticism I have is that the pricing on the website is not as clear as it could be. You do give all the info. but the biggest font is used for the bulb price without vat or postage. As most domestic customers will be paying vat anyway, I feel that should be the price most prominantly displayed. However, as long as they last, they're still good value.
