They claimed to have achieved 276lm/W at 350mA in a neutral white color. Based on that I think LEDs will continue to improve for us, although 276lm/W neutral white is near the upper limit of what physics can allow. The blue chip used in that test may be above 90% efficient. We will be getting away with a lot less heatsink in the future.
