MH White vs metallic silver reflector

[wooden_reefer]

If your MH reflector is white not metallic silver, are you happy?

Do you tend to think that even with a white reflector, most light rays reach your tank?

The way I understand is that white also reflects most if not all lights, but the reflective angles are irregular. May be after more reflections most light eventually manage to reach the tank. Parabolics does not make sense for white reflectors.

Many lamp shapes are white inside.
