LEDs range in price and quality We have adopted our own rating system to help you identify which LEDs are the most reliable:
A+ = Zero failures A = Approximately 5 failures per 1000 units sold B = Approximately 15 failures per 1000 units sold C = Approximately 25 failures per 1000 units sold D Would be around 50 failures (or 5%). LEDs with a D rating would not be offered by us.
