Transparent shader with color property and no lighting help


I found the transparent diffuse shader online, but how do remove the lighting from it?

or if there is a shader out there with

Transparency, Color property (to change the alpha val) and no lighting please let me know

Shader "Transparent/Diffuse" {
Properties {
    _Color ("Main Color", Color) = (1,1,1,1)
    _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
SubShader {
    Tags {"Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent"}
    LOD 200
#pragma surface surf Lambert alpha
sampler2D _MainTex;
fixed4 _Color;
struct Input {
    float2 uv_MainTex;
void surf (Input IN, inout SurfaceOutput o) {
    fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color;
    o.Albedo = c.rgb;
    o.Alpha = c.a;
Fallback "Transparent/VertexLit"

found one

would be nice to know if this is better than Transparent/ Diffuse shader.

i am making an assumption it is as it is not using lighting
