Can I use LED's with the Walstad Method?

I am a new to planted tanks. Heck, I am new to fish. The last fish I had was a goldfish in a bowl that I won at a carnival when I was nine. But this time I want to do things right. I have been doing research for the last month and I decided I want to start with a 20 gallon long. My question is this:
Can I succeed with the Walstad method if I use LED's instead of fluorescents? (More specifically Finnex 30" Fugeray Ultraslim + Moonlights)

From Finnex RAY II & FugeRAY PAR Data

Notice that if you have virtually no substrate in the tank you would get about 48 micromols of PAR, but if you have 2 inches of substrate that goes up to almost 70 micromols. Both numbers are way too much for a Walstad method tank. For that you should try to stay beween about 20 to 30 micromols of PAR.

If you can hang that light above the top of the tank, you could use the 24 inch long version, and hang it about 6-8 inches above the top of the tank, getting around 20-30 micromols.
