  • The wattage or light output that you need in a Fluorescent Bulb to match the wattage or light output of your current incandecent or Halogen Bulb can be found In the chart below:

                                 Fluorescent             Incandescent
                                 4-7 Watts 25  Watts  
                                 9-11 Watts    =  40  Watts 
                                 13-16  Watts 60  Watts 
                                 18-20  Watts 75  Watts 
                                 22-25 Watts = 100  Watts

  • The Color that you desire is found in the Kelvin Color Rating Listed for Each Bulb on our site. Your kelvins (color Temp) will have a K after it on our site. To best match your current incandescent bulb, we advise purchasing the 2700K color bulbs found on our site.  You will note that Each bulb has a Kelvin (K) rating on our site.  This incandescent light bulb color temperature often seen in today's typical incandescent bulb is referred to as "Warm White" as it has more of a "yellow" color on the light color index. The higher the Kelvin color temperature of the bulb the whiter the color will appear to the eye. 6500K is the "whitest" color bulb we offer and it most closely resembles daylight. The higher Kelvin color temperature bulbs may be used in areas that are task oriented. Kitchens, Bathrooms and reading lights are where these bulbs are found in residential applications. These bulbs are rarely found in Living, Dining, Family or Bedrooms. These rooms are almost 100% "warm white" or 2700K color bulbs. If purchasing for a retail application you may wish to purchase the higher Kelvin colors to create energy and the feeling of "daylight"

  • You will need to know your base type. Please take a look at the base types in our Your base type guide and select the one that works with the fixture your are purchasing your bulb for. The "standard" base type that is found on most incandescent bulbs is called E-26. The smaller shape used with some candelabra bulbs is called E-12. The new fluorescent light fixtures use a GU-24 base shape.

  • That Par means Parabolic Aluminized Reflectors (PAR)-Outdoor flood bulbs that are resistant to damp areas. PAR bulbs are used for spotlighting or as flood lights.  PAR is the trade designation of a type of lamp that offer "flat" lighting and is widely used in commercial, residential, and transportation illumination.  Flat lighting can be defined as even front lighting of a subject, producing little contrast, no shadows, and no modeling. 

  • You should always look for EnergyStar approved bulbs. Bulbs with the United States Federal Government EnergyStar approval have passed rigorous life testing, performance testing and energy utilization testing. The bulbs on our site are all EnergyStar certified. This is the reason for our somewhat limited selection for each bulb type. When buying from Wholesalebulbs, you have the peace of mind of knowing that if the bulb is listed on our site, it is of the highest quality and meets all of the demanding requirements of the EnergyStar Standards Body.
