I am glad pond snails never made it into my bowl. pretty unheard of - having a planted tank w/o pest snails :P jk
yes the lamps is from ikea for about $20. i got mine off [Ebay Link Removed]
it may or may not be good enough for actually growing out plants to fill a bowl. i grew mine with a 11W CFL, and then in the last few months replace with this LED. it has done a good job of keeping the plants alive and well. They do grow, just probably not as fast as under the CFL. its only 1W after all lol.
I have some extra yellow shrimp in my bowl if you want them.
