I LOVE these bulbs. They are very inexpensive and exactly the right bulb. I can't find these bulbs anywhere else, either. I needed these 5V bulbs to replace some burned out ones, and somebody at Home Depot sold us 15V bulbs (!!!). Uh, no, and I wouldn't try to put anything other than 5V in any string of lights attached to my house. Yikes! These lights are perfect, and great price, too.
