That performance was accomplished in an R&D lab a couple of months ago. Who knows when that will be commercial reality.
I found this on the Philips web site under LED myths. I think it is applicable to the R&D result you linked to.
Myth #3: White-light LED sources produce over 160 lumens per watt
Many manufacturers test their LED chips on lab benches at room temperature with short pulses that produce a high efficacy that cannot be achieved in practical use. While these results are not incorrect, they do not reflect the typical expected output of LED sources integrated into lighting fixtures. Although percentages vary, it is not uncommon to see efficacy losses of up to 40%.
Reputable LED fixture manufacturers do not base lumen measurements on the test results of their LED source suppliers. Instead, they use independent, third-party testing labs to measure and validate the output of their lighting fixtures according to test conditions spelled out in the LM-79 standard, published in 2008 by the Illuminating Engineering Society of North America (IES).
Some highly efficient white-light LED lighting fixtures can achieve efficacy of over 40 lumens per watt (lm / W), sufficient to earn ENERGY STAR and other energy-efficiency ratings. For example, linear LED cove lights from a leading manufacturer achieve efficacies of 43.9 to 53.1 lm / W in normal operating conditions.

Here are reviews of the flashlight you linked to.

As you can see the 3000 lumen rating is unrealistic.
