Headlight advice please.

With winter setting in, I want to replace the dull yellow headlight bulbs on my new shape Civic SR for some bulbs with decent output.
I have been advised these:



I want bright(er) but these are 8000 lumens anybody know about legality etc of that much light? In addition these things have cooling fans! Is that normal and could they melt the headlight cluster for example.

Any advice appreciated.
