I believe it is important to note the voltage of the LEDs. I have experimented with many LEDs over the years, and found if The LEDS is only 12-volt, they will have a short life, compared to a 9 to 30 volt LED. I have also found the boards to direct the light better than the bulb type. I prefer the White, for more light. I have ordered from this source, with no problems.
This is a very good LED, especially at $10:
