The drivers make the difference
A number of LED products are hitting the stores. Some are excellent but most are poorly designed and have a huge failure rate. The key problems seem to be heat sinking and power supply. LED's are phyiscally robust and electrically fragile. A small voltage change in driving the led's cause huge current changes in the diode causing failure. Heat as in any other electronic component must be extracted and dissipated for it will also cut down life of the lamp. Most of the plug and play LED solutions suffer from both these problems. LED's must be driven with constant current drivers to ensure the best illumination and life for the lamp.
