White plastic vs polished aluminum refraction (cob reflectors)

Hey, so there is a white plastic one "extra wide" and polished aluminum "wide". I got the angle part, but I was under impression that polished aluminum reflects light way more efficient than white plastic? I have both and it feels like I wasted shekels getting the white ones...? Am I not getting it the right way? May be it's some sort of new gen poly that does it just as well as polished metals?

spray em with some silver paint and you will feel better.

White surfaces do a surprisingly good job of reflecting light. If you're worried about the amount of light you're losing due to reflector coating then you better have a few cups on your shelf...
