Push Fit (2 and 4-Pin) Light Bulbs
Compact fluorescent bulbs with a 2-pin or 4-pin push-fit base are designed for use in new building fixtures where a specific lamp rating is required. 2-pin light bulbs and 4-pin light bulbs have distinctive cap types that are unique to the wattage and type of the light bulb. When replacing these type of light bulbs, care must be taken to choose the cap type of exactly the same type as the bulb you are replacing.
