I am still in the DIY mode, although the benefits are getting smaller as more and more manufacturers incorporate the light spectrums that have been used by the DIY'ers for a number of years.
@daveH has been pretty happy with his new MaxSpect Ethereal units -

I went out and bought the maxspect, amazing light, not cheap but very happy with the colour it gives. Excellent features that i didn't think i missed are back. The app is terrible but i can live with it.
