Right, a good led light is hard to distinguish. I have some old Phillips led bulbs I've had for 10years. A-type with the heat fins. They were designed to last unlike the bulbs today. Leds will last forever, it's the LED power supply that breaks down from heat and poor quality components.  They are truly designed to fail as my two bulbs prove. They were making them decade bulbs but now the don't last as long as an incandescent and that generally defeats the purpose of their existence.
