Welcome to the forums : )
3w LED chips typically work with 18-24" of distance from the canopy.

You're a bit under-powered with just the one bulb. I'd start with just one of your plants if that's the only bulb you have.

Happy grow.

I keep my 6 band LEDs 12-16 from the top and they do great. If you're interested I got mine from this company I highly recommend that is based out of Utah. I've had good results at that height with those so far. I'm about to harvest on week 6 of flowering.
