50W LED is a lot of light, or should be, 6000 lumens.
The halogen bulb has reached it peak Olaf, it did so about 25 years ago, there is no further improvement possible.
The trouble with these LED bulbs is that they are all made in China and you cannot believe the watts consumption or the lumen light output figures.
Your reflector headlight was designed to have a halogen filament, of a particular size, burning in an exact place withing the headlight. An LED does not have the same so the beam pattern will be all over the place. That is why no vehicle manufacturer uses an LED bulb in a reflector headlight that was designed for a halogen bulb. It would also be illegal in most countries.
This was my experience of the LED when I tried it out on the K and also on the car. Lots of light but it was no good for driving. In short good for being seen but not for seeing on rural roads at night. One lot I got came as 30W but closer examination proved it to be 3W supposedly equivalent to 30W globes as fitted to Japanese bikes back in the 70s. On the car the reflector headlights which have new reflectors and new bulbs work very well but high energy consumption. When I tried LED H1 and H4 they were no good. I then replaced the reflectors and hey presto brilliant improvement.
I was getting tempted to try again and decided to wait and see what a road test would show on this thread as there wasn't mention of one.
Given my previous experience with LED and with the car I decided to order a brand new reflector for the K headlight.....with a cleaned up lens, a relay wired and a clean bulb in I will probably get as good as can be got from olde worlde technology. £25 for the reflector added to an order didn't break the bank.
