Been looking around for led lamp with a narrow beam, most available are around 24-25 degree beam, this might even be the ideal beam angle for a stairwell.
But I have found a super led GU10 which has a 18 degree beam available in 3000k warm white & 4000k cool white & dimmable, disadvantages, it's £25 & it's too long for a compact fitting.
