I bought this LED bulb before 7 month. I bought 2 LED bulb. When I bought these in beginning it works very good and fully brightness. After 3 month of using one bulb is damage and another one have very low brightness as compare to starting. I bought these two bulb because of more usage in kitchen and hall and both are fitted in that. But when I see electricity bill of my house it was too much as compare to previous one. Finally I decided not use these company bulb and I also suggest to purchase another bulb .
