This is a bit off topic, apologies but I found the video linked below rather interesting.
Summary, it's from Headlight Revolution, an outfit based in Bemidji in Minnesota, no connection other than I've been impressed with their knowledge and helpful attitude. The video is a comparison of light outputs of HID vs LED upgrades and, as they're a US outfit, using lamp units from US vehicles, both reflector and projector types tested.
Whilst the absolute light measurements are not definitive and they take pains to make clear the numbers are only useful as comparisons within the test, I was rather surprised how poor the output from projector units was. Clearly it needs further investigation, e.g. light source location may not be helpful, but it really confirms much of what I've found that projectors are a bit of form over function.
PS yes don't lecture me on HID upgrades and their legality, I hate the as much as the rest, personally run 4*H7 incandescent lamps. Currently trying Philips Racing Vision, suspect their shorter life will not be offset by any supposed improved output.
