These are all 3 packs of Authentic Scentsy Light Bulbs.  There are 3 different sizes to choose from depending on your warmer size.   The 3 different sizes are used in the various warmers listed below.

A 3 pack unit of 25 watt bulb is used for large warmers

A 3 pack unit of 20 watt bulb is used for mid-sized warmers or 3 piece warmers

A 3 pack unit of 15 watt bulb is used for small warmers such as nightlights and the plug in base with small top.

Because of a previous request, I am now listing a 3 pack of bulbs as a combination of 1 bulb of each of the wattage.

Assorted 3 pack unit of 1 bulb of each 15 watt, 20 watt and 25 watt.

 

Packaging may vary as seen in the photos.
