Ceiling Fan Running Slow Reasons ? There are various problems that can happen with a ceiling fan to decrease fan's speed, Those are mechanical and those are electrical. Mechanical Issues for slow speed of a ceiling fan :  Bearing Problem Poor blade balance  Electrical Problem :  Bad Capacitor  Winding Problem Troubleshooting these low speed ceiling fans ? Switch off your ceiling fan and wait until it  stops totally . Now spin the blade with your hands, If you feel difficult to turn that means it cause bearing or lubricants problem .If the blades spin freely that means you should change the capacitor.Now again turn on fan and feel sound if it's make a squaring and grinding sound it indicates the problem of bearings or lubricants  . In this case you have to change bearings.  Check all blades balance. Don't forget to check the speed regulator. Sometimes ceiling fans get slow for speed regulators also.  Ceiling fan repairing Add lubr

Hi i will share how fluorescent bulb saving energy and incandescent bulb wasting your energy. Basically incandescent bulb made with a filament . Which is making like a short circuit between phase and neutral. When phase and neutral connecting it's lighting . That's why it is taking too much energy this is really waste of energy . It's a electrical bulb . Fluorescent bulb benefits Fluorescent bulb benefit fluorescent bulb lighting with a electronics circuit . This circuit converting phase and neutral as a 15 watt or 23 watt (depends on bulb power) power.And it's supplying on bulbt filament .And this bulb fully made with gas so it's flashing like as high powered bulb. so use fluorescent bulb and save your electrical energy save your money . It's a electronics bulb. 23 watt fluorescent bulb = 100 watt incandescent bulb .so you are wasting about 4.34% energy. So save your energy .use fluorescent bulb save your money . Than
