I put a new light in my lamp but it won't turn on, why is that? Verified
Some lamps are made for light sources of a specific wattage. When a light source is inserted that requires a higher wattage than the lamp can provide, the light may not turn on. If the lamp delivers a much higher wattage than what the light source is made for, the light source can burn out.
