[QUOTE="Geoff1946, post: 512818, member: 28452"] I honestly believe that the unreliability of many led lamps is down to bad design and poor quality manufacture. Most components, including LEDs are inherently [I] r[/I]eliable AS LONG AS used within their specification.. I've dissected quite a few failed lamps and usually found capacitors at the limit of their voltage rating operating in an area with poor heat dissipation. Similarly the bridge rectifiers seem to be very small for their intended purpose. Next, the leds are often over-driven to achieve extra light output. They are then sold, cheap as chips, in the knowledge that they will be replaced soon. It's a marketing policy I think. If units are properly designed with under-stressed components they will last for years, but there isn't a lot of incentive for manufacturers to do this. [/QUOTE]
