Cartier, the renowned French jeweller, is now outfitting their display cabinets with Lamina’s SoL MR16 LEDs which use just 8 Watts of power to produce the same light as a 20W halogen. See if these eco-friendly bulbs are right for you in our video review:

As you can see Lamina’s bulbs improve on some of the issues we had with previous LEDs reviewed here but still come with a high initial cost. They will pay for themselves over time, but many will want to wait for the price to come down in coming years. Here’s how I rated them:

• Green: 4/4
• Value: 2/3
• Quality: 3/3
• Final GreenDeals score: 9/10
