What Wren was trying to say is that normal fillament-type bulbs radiate light in almost every direction, and the reflectors do their part in focusing that light. LEDs have their light already focused, and is usually pretty linear. So no matter how bright the LED is, it won't be seen nearly as well as a normal bulb would be, given the LED bulb is placed in a housing meant for a fillament bulb.
Even then, he is right about the DIC issue too. LEDs draw far less current than a normal bulb, and can only draw it in one direction. The DIC will always think that LED "bulb" will be blown, even though it isn't.
