Common Fan Clutch Problems. The most common problem encountered with a fan clutch is when the car overheats while it is not running. This is when the fan clutch does not work properly and thereby decreasing the car air conditionerâs performance as the fan clutch also cools the condenser of the air conditioning unit.
Also referred to as Maximum Overall Length (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
Watts and lumens measure two different things. Wattage measures the amount of electrical power the light bulb consumes. So in the old days, when we shopped for incandescent light bulbs, we loosely estimated the brightness of a bulb based on how much power it required. Lumens, on the other hand, measure the actual brightness â regardless of how much power is needed.
