uniform mat4 u_MVMatrix;
uniform vec3 u_LightPos;

attribute vec4 a_Position;

attribute vec3 a_Normal;

varying vec4 v_Color;

const float ONE = 1.0;
const float COEFF = 0.00001;

void main() {
    vec3 modelViewVertex = vec3(u_MVMatrix * a_Position);
    vec3 modelViewNormal = vec3(u_MVMatrix * vec4(a_Normal, 0.0));

    float distance = length(u_LightPos - modelViewVertex);
    vec3 lightVector = normalize...
