Color Discs?

OK, So I made a build and used a White Cree XP-L (If i'm not mistaken) which is available from TCSS.
And I bought bought color discs. I found out The color isn't very strong and isn't very bright.
Should I buy a Real colored light?
Is there a way to enhance the light?
Thanks

Buying LEDs of the desired colors will almost always be brighter than filtering White light to a specific color, especially if multiple filters are being used simultaneously.

Thanks I will keep that in mind for next time. I learned something new (At a cost) :)

In reality there is no "white" light, it's the combination of multiple wavelengths. When you filter it you are subtracting light away, at the cost of battery life.
