Basically it is diminishing returns at higher power. Also lower temperatures will make LEDs more efficient. This is true of all LEDs I think. LEDs are improving all the time, there is a lot of rivalry with the big brands to make the most efficient ones. The Cree CXB3590 and XP-L are the most efficient white LEDs available at the moment.
