1. Please confirm the voltage first. If the voltage of a product is 12V-24V, then you must use a professional LED voltage converter. 2. Please check the specifications of the product carefully before ordering to insure a proper fit. 3. Do not disassemble any bulbs by yourself. 4. Be sure to cut the power off before beginning installation to avoid personal injury.
I ordered 5 of these and they fit my USA standard E26 socket perfectly. The light is white vs my old bulbs which were yellow. If you are looking for a 60W equivalent bulb this is it. This price is cheaper than Home depot or Lowes who are just starting to get "60W" LEDs but they cost $12.00. My prediction is that in 3 years you will not be able to buy either an incandescent or a florescence bulb, LEDs will rule! This bulb is priced just right and I will change it when my 3 year old graduates collage with a masters degree.
