Review on TORCHSTAR Dimmable Spotlight Equivalent Certified by Michael Gupta

I have bought a Torchstar 15W (120W equivalent stated) and a Sunco 13W (100W equivalent stated). It's actually hard to tell them apart. I probably wouldn't distinguish them in a cool white (4000K) blind test. In the warm white version (3000K), the Sunco 13W appears brighter than the Torchstar 15W. Dimming works well on both brands, with no in-camera flickering.
