Hello
X-Cite also has a new LED system that is close to the price of the Sola but brighter for DAPI and GFP.  You are able to control individual LEDs which I don't know whether you can do with the Sola.
X-Cite also has some useful ways to program very fast sequential pulsing of the LEDs and they guarantee 20k hours.

The Sola from Lumencor is a great epifluor source from what I hear. Spectrum output is similar to that of typical metal halide systems like the x-cite, and you don't have to worry about modules or any of that stuff. It puts out continuous white light from 380-680nm, and lasts 15k hours.
