Review on OTTOSEA Spotlight: Unmatched Daylight Landscape Illumination by Daniel Jenkins

I ordered this set of 6 OTTOSEA LED spotlights 12V AC 5W (equivalent to 50W), 6000K Day White, GU5.3 Day White and they were as described a "perfect replacement for a 50w halogen bulb." I only needed three but they came in a pack of 6 which was good because when I installed and switched on the 3 bulbs I needed they lit and only 2 remained.The third arrived and went out immediately.I replaced the defective LED bulb and now have three working spare LED bulbs and two untested spares.I would like to replace the defective one but don't see a way to do so, without returning all 6. I will only keep the ones that work and look for better quality bulbs when they fail.
