I have two sets of the aquarium grow light ones.

SOLMORE 16.4ft 5050 Grow LED Strip Light Aquarium Greenhouse Hydroponic Plant Garden Flowers Grow Lights 12V https://www.amazon.com/gp/product/B00WJZ0LNA/

I've had decent results with them but this set seems to be no longer for sale. I just peeled off the backing and stuck them to a poster board. I paid around $20 total for the setup but that was two years ago.
