Opie,
Had the same thought awhile ago, but my testing w/ white LEDs last year was less then stellar. Plus LED whites are not rated like fluros in degrees Kelvin, but rather an x/y plot. Hard to figure which is which.

My solution was to combine Red Cree XR xlamp LEDs with T5 fluros.
I've replaced a 600w HPS with 160w of LED and 198w of T5.
I'm 1/2 way through 2nd try with it and it works great!

I see no reason why the correct warm white LED could not replace the furos.
