bulbs bought at wal*mart?

I bought a pack of these over a month ago. I put two bulbs in my 26g and they are going like crazy. I also put two in my gold fish tank but he keep rooting them up so this Tuesday I put them in a new 10g that I will be adding puffers too. I repaced them with 2 new bulbs and notice today that I saw a little something popping out.. So, so far mine I been doing good..
