I everybody,
I’m new to Corona, I have an issue with the IES light, they appear as a black dot on the render itself, I already try deactivating the Visible to camera option.
Hope anyone con help me 
Best Regards
Then it’s likely the shadow you’re seeing. Try unchecking “occlude other lights” also, and see if it helps.
Thank you PROH, that was the fix!
+there are some IES-related fixes in the 1.4 daily builds already if someone is experiencing any problems like noise/slow rendering
yes i definitely experienced lots of noise with IES lights in one of my scenes with ver 1.3.. I had to keep LSM slightly high and keep rendering until cpu smells like hell
