I purchased a Wurkkos FC13 a while ago and it had the greenest, ugliest XHP 50.2 I'd ever seen. Probably the ugliest emitter of anything in my collection.
So I got a SFT40 in 3000K from Simon to put in it instead. My first emitter swap. Seems decent. The driver is just FET, but it's certainly not ugly anymore.
