Can LED strobe be as fast as xenon?

Can you define pulse width min? or rep. rate? No problem except brightness is proportion to duty factor which affects smear. But I think no problem with 3600 RPM 1% d.f. or a toy at 500 RPM.

you can't exceed maximum current unless you risk fusing the tiny gold strand wire but you can always oversize the LED power in parallel.

All diodes have capacitance and resistance the effect is an RC=T time constant but it is a lot fast than you can spin art. The issue is Xenon dumps all its power in flash but LED's cannot increase the average power to the same as steady current. So if 1% or 3.6 degrees is OK that's 1% brightness.

3600 RPM = 60 Hz divide by 1% is a pulse width equal to a 1 cycle at 6000 Hz every rotation. You can do that duration with a variable "1-shot" and adjust phase or angle with another variable.

All you need to is define all these variables and maybe Grok or GPT can spit out an answer

may the force be with you.

"Normal" LEDs should work fine, but any that use a phosphor to change the light output spectrum (like most white ones) may be visibly slow cutting off in a high speed application. (I have no idea how slow though)

An RGB LED with separate terminals for each colour could probably be used to give white, using appropriate resistors for each element to balance the colour levels? Or separate high output R,G & B ones.

Most LEDs can work fine on somewhat higher currents in low duty cycle applications, such as multiplexed displays - or this. Check the manufacturers data sheet for the pulse ratings.
