For someone who has no idea about light engineering or electronics if I stack two 25k Lm lamps next to each other does it make 50k Lm light?

I recently changed my car's headlamps to Chinese LED which claims to be about 37kLm and I don't know how much it is probably less than that.

Two of those lamps costee me around $24 on Amazon US (pretty sure under $10 in China).

What makes this $800+ ?

Please don’t put in extra bright headlights on cars. Stock LED headlights being to bright for other drivers is already a massively common complaint — and then we have people installing even brighter ones? Please don’t.

It is also illegal to use non-DOT approved lighting in the US. Was behind a jackass today with a receiver mounted accessory red light that was excessively bright and made it look like the brakes were applied.
