But the spec makes no effort to distinguish when each should be > used. > > The confusion applies especially when using feSpecularLighting with an > feSpotLight. > > At the moment I am assuming that the spotlight one is to be used when > calculating the spot light colour as per the formula in section 8.10 > (feDiffuseLighting). And the one from feSpecularLighting is to be used when > calculating the final pixel colour as per the formula in 8.19 > (feSpecularLighting). > > Have I got that correct? Either way, I believe the spec should be clarified. > > From my testing, it appears some browsers have bugs related to this issue. Could you upload your example please? How do SVG viewers differ?
