How reflective is Aluminum Tape?

Does Aluminum Foil Tape have the same back reflectiveness as a regular piece of Aluminum foil?
I am looking to build my own reflector for my CFL's and am wondering if anyone knows the answer. I am doing a micro grow and also considering lining the walls with the tape.

do you have a light meter? if you do try to bounce a direct light, like a flashlight off of it and see what reading you get.

For a small grow you should consider using the dispoable aluminum baking tray's and such from the dollar store. Just cut them to size and they should work just fine. I personally have 2 aluminum roasting pans being used as reflectors for my CFL grow lights and they work great (cheap and effective).

bump... I was wondering for when I use the tape for the corners should paint over it with white paint or is just the tape better?

y would u paint if u aluminum foil only need one right

flat white paint or mylar is much better

i thoguth that too
cause i had a rooom well a closet with regualr white paint not only did it maKE THINGS LOOK SO MUCH NEETER IT ALSO DID WORK QUITE WELL

Aluminum tape is just aluminum foil with adhesive on the back. So yes, it's the same.

You can also pick up a can of mothers aluminum polish, you can get a mirror finish on that tape..
