My post #6 above has links to eBay for the H7 200% at £23.99 for 2, so £47.98 for 4
H7 150% at £18.94 for 2, so £36.88 for 4 which are the ones I installed in 2019.
The TQL are a replacement headlamp unit with a lens to configure the beam pattern and use a H7 in the dipped side and a H1 bulb in the main beam side.
I have no experience of these units so cannot comment other than the LED DRL does look more contemporary.
As I explained in the earlier post that I included, I was used to an Audi Q3 with Xenon lights so missed the much whiter light. The Night breakers were a good compromise, brighter on dipped than the original VW ones and it is no contest on main beam.
I don’t get any adverse flashes from other drivers and I rarely use the levelling function to bring the dipped beams down if the van rear is down due to load.
So for me just under £37 the improvement was really worth it. For £10 more for the 200% May be worth it but life will be shorter as they run hotter to emit more light.
No issues with excess heat on the headlight plastic and no discolouration in 4 years.
Would an extra £600 for the TQL be worth it for the LED DRL and projector units?
Get the Night breakers fitted and then decide would be my take. You could always recover 50% or more on e bay if you had the TQL lights demonstrated and decided you couldn’t live without them.
Regarding installation Halfords is £18 per pair (so £36) if skinned knuckles do not sound that appealing and Osram have an installer locator.

The Osram upgrade is an improvement on what you have.
