Review on Sylvania 40808: High-efficiency Temperature Control at your Fingertips by Ricardo Malhotra

These bulbs appear bright and unlike many LED bulbs, they illuminate the entire bulb, not just the top. This makes them much more useful and attractive for some devices. They don't have much time so I can't rate durability but they seem to be of high quality which is what you would expect from a supplier like Sylvania. Only minus? They're quite expensive compared to regular LED bulbs, but they're made differently, so you should expect at least some price difference.
