These days we see a lot of LED lighting on events. It makes sense, LED’s don’t get hot, last longer, use less power, … Unfortunately LED stage and disco lights often make the job of a photographer harder. This has to do with frequencies and non-complete spectrums. They are not unworkable but you really need to keep an eye on your exposures, certainly in high iso shots. When you get too much contrast and dynamic range in your pictures, you can get some pretty nasty artifacts like in the picture below.
