I converted my triple to a single 2+ yrs ago. I’ve gone through many configurations over the years. First was a custom, intermediate length bezel made for using an S21A reflector, then later an odd 20mm TIR. After this, I bought a SS bezel from Neal and have been using Ledil Leila optics. First with sliced SST20w, then the Nichias, and I’ve been back to a domed SST20 4000K. Pretty happy with the current setup. 22kcd with an ~11 degree spot and 95CRI. 8kcd runs indefinitely without hardly getting warm.
