I was a bit skeptical about buying bulbs given some negative reviews. I've replaced all my halogen bulbs in landscape lighting with LEDs (34 in total). I'm tired of changing lightbulbs every few months. The bulbs are a little bright compared to the bulbs they replace, but the original ones were a little dim. It's been over a month and I haven't had any problems. No flickering or premature failure yet. I will update if anything changes. When they first appeared, they were too expensive. A few years have passed and the price has fallen. It is not easy. Highly recommended.
