A phosphor blend for an LED light source is provided wherein the phosphor blend comprises from about 7 to about 12 weight percent of a cerium-activated yttrium aluminum garnet phosphor, from about 3 to about 6 weight percent of a europium-activated strontium calcium silicon nitride phosphor, from about 15 to about 20 weight percent of a europium-activated calcium silicon nitride phosphor, and from about 55 to about 80 weight percent of a europium-activated calcium magnesium chlorosilicate phosphor. An LED light source in accordance with this invention has a B:G:R ratio for a 3200K tungsten balanced color film of X:Y:Z when directly exposed through a nominal photographic lens, wherein X, Y and Z each have a value from 0.90 to 1.10.
