Are you sure it wasn't the method I said above for BEL? Because I learned it from Wilbanks' thread at MM:

There's a small chance it might work for albinos...but I don't know how reliable it would be. I actually don't have a normal albino BP in my collection to test a mag light on. I assume since the eyes on the albino are red then they will glow just like the banana BEL does and therefore not be reliable
