Do light fixtures and lamps really need to have specific wattage bulbs? Why?
Using bulbs with too high a wattage can cause lamps or fixtures to overheat, posing a fire hazard. You should not use bulbs with a higher wattage than those specified by the fixture manufacturer. The wattage required is usually imprinted on the fixture or lamp or included with the product packaging. If you are not sure where to find this rating, contact the manufacturer.
