Probably something like
A few 50 or 100W LEDs mounted on fan cooled Duron heatsinks..
Meanwell LPF drivers (1 per 100W LED)
No idea how much power this "treatment" really needs though.
The short 20min duty cycle "may" be your saving grace as far as heat goes..
BUT I base my time calcs off having a heatsink and the time it takes that to reach thermal stability (between 30 minutes to 1 hour).. I'd expect the LEDs like you have it will get up to temp in fairly quickly (5 minutes or less)
My wife suffers from a "similar" disease (in the winter months only as she gets plenty of sun in the summer)..
When/if it bothers her she either just hits the tanning beds every few weeks or we just go to the beach house in Florida and hang at the pool..
BTW.. Make damn sure your victims NEVER look at the LEDs like that.. Permanent eye damage can happen VERY quickly with high power LEDs.. I'd suggest welding glasses.
