I'm wondering that myself. Not just for the burden on the electrical system (which I am sure is less than halogens), but to get an idea of how hot these units run. I've found that when many of these LED units get up there in lumen output, they start requiring external heat sinks. Some of the bulbs, not all but some, have integrated DC cooling fans on the rear section of the bulb assembly. As a desert car that runs into the occasional dust storm, I don't need silt gumming up the blades and bearings to cause a premature failure.
With a color temperature of 5,000K, you should be ok. Although there is no listing of what the lumens are.
5K is the max I'd go with for any bulb on color temperature (save for fog lights which I prefer the yellow 2,500K in bad weather and to see animal eyes). Once you start getting a blue tint to your headlights, that's when you begin to decrease your vision.
