OMG, when you first look at this small "Cute" light bulb, you have to laugh! But it does screw into a "Normal USA lamp socket! I love them! I have bought the bulbs that only "use" 1-watt of electricity and the bulbs that use 3-watts and they are fantastic!
I have been an Electrician for over 55 years (I'm old lol), but I just have one of these in a lamp in the Livingroom at night and it is perfect! Safety: People think I am awake and don't bother me or my house! I put them in different rooms throughout the house, and they Only use or 1 or 3 watts! No need to have higher wattage light bulbs! The house is more "Secure" and this old man doesn't have to mess have light switches (I can see just fine with them) and No one knows from the outside, what room I am in or where I am!
They shipped from over sea's and are packaged (protected) really well! Mine came from Hong Kong really fast Usually in about 10-days, depending on everyone's weather conditions and never broken! Thank You, Seller!
