Car lights comparedSo, whilst driving in the dark I though it might be interesting to actually see what the difference is between the different car lights. Especially since my xenon lights died on my Citroen.
What I dtried to do was make a setup where I can compare different bulbs. Not in absolute values, but relatively. So I got a cardboard box and a light meter.
The light meter was set to max 20.000 lux (the 2000 lux range is not enough). All bulbs were put into the same hole and set to their highest light output position.
I tested 4 bulbs:
First started with the Osram bulb.
Then the 4300K xenon bulb.
Then the 8000K xenon bulb.
And lastly the standard halogen bulb.
To put everything together:
From the results it seems that new and used makes quite a difference. I think the 8000K should be lower then the 4300K when new, but it isn't in the test. If the same would go for halogen bulbs, then the Osram lights don't seem to be a big improvement on standard lights.
