You'll never get 5000K out of a halogen. All they do is put a blue coating on the bulb to try to "whiten" the light emitted from the filament so even though you may get a slightly whiter light, you lose some of the lumens output unfortunately.

The ones @mikejtownsend posted looked so much whiter yet was 3800k ish
I bought some white looking ones for a previous Astra J, looked whiter, but weren't actually any brighter. Led's are good, but unless fitted from factory are not legal. As it's hard to judge from a photo.
I'm staying put with my Lidl up to 100% brighter bulbs, they're OK and better than factory, although still a bit yellow.

I get where you're coming from by that Chris but it's fairly obvious to anyone who knows even a little about cars (and you would've hoped the mech's doing the MOT would know :ROFLMAO: ) the difference between a Halogen incandescent headlight output and an LED headlight output. I don't know if I'd be willing to risk that in an attempt to get it through the MOT. :unsure:

Then again, just how many testers actually do a thorough test ? There's a fair few horror stories on t'internet about set-up ringers being sent into garages for MOT's and them getting a pass with fairly serious faults.
