if you look at the specifications you will see they are no brighter (1000/1600 lumens stated) then a regular H4 bulb and they are a worse 6000K

this is where old sealed beam head lights get a leg up here, those are themselves a standardised size/form-factor, the 7 inch sealed beam in Proper lightbulb terms is PAR56 and so with a small* electrical system upgrade, @IronStar could for "experimental purposes" fit a pair of these 4541 450W Aircraft landing light lamps to his mini with no body modifications needed at all  

Some relays and a bigger alternator, and it’ll be right 😄

I could also do something silly with Yugo Cabrio as well. It has US-spec front lights, which are H6054 sealed beams, which probably also have interesting upgrade* options? 😄

They certainly have round here. I used to do 4000miles a year on my bicycle commuting to work, but have cut that right down the last year or so as it’s just too aggravating.

Glad that you have done that mate. Yesterday, I was put with Alison. Queuing traffic at temp' lights. 

I was watching both mirrors whilst waiting- training innit- and spotted a pedestrian in a rush.

They ran between car behind and Alison and almost got taken out by a pizza delivery rider.

He was on the case. Was fucking close. And the pedestrian- completely ignorant to the heart in mouth moment- just put their hand up as though to say sorry and ran off...

im afraid not, there might "off road only" high wattage versions you could get, like the 80W/100W "H4"'s I linked to, but the rectangular sealed beam was produced purely because of fickle car designers and consumers, optically speaking a round reflector/lens is most efficient, so for serious performance applications thats all you will see, so theres no silly Aircraft landing lamp you can put in the place of a US rectangular sealed beam

 

honestly thats one of the things I find most perplexing about LED headlights, as I have demonstrated, theres no reason, one cannot have stupid bright incandescent/halogen head lamps, if you wanted to, but the reason we dont, is for practical safety reasons, the reason H4 bulbs are what they are is a trade off between performance for the person behind the wheel, vs not glaring everyone else coming the other way off the road

 

so I have genuinely been quite perplexed as to why modern LED head lights have been allowed to be so bad in that regard, theres no reason they *have* to be that bad, and yet here we are...

Well, whilst you can run stupidly powerful incandescent lights, they are rated for XXX W per bulb, which requires both much thicker wiring, much more powerful alternators and results in tons of heat. Modern LED lights are 15-20W, even for the super modern super bright matrix lights and associated electronics. I would also argue that optical construction of lights themselves evolved. I’m old enough to remember just how much better the lights became with the advent of projectors vs standard reflective headlights. 
There’s a very uncomfortable bit of automotive history, where we switched to these ultrabrights, but the technology not to blind other road users wasn’t there yet. Switching to matrix realistically alleviates this issue through electronic wizardry. I really wouldn’t like to be one owning these after a minor bump that takes out the 4 digit priced light cluster, or in 15 years when electronic gubbins start failing.

Thank you for out bulbing me, and actually reading the data sheet. I was thinking about buying a pair of H7s next time I am in Germany but won’t now. Also not helping myself because I fit whatever shit H7 I have to hand anyway when I need bulbs!
