When to Buy 4 Instead of 2

The decision between the 2-pack and 4-pack is purely economic and practical. If you know you need 4 or more bulbs, such as a ceiling fan with 4 sockets, a living room with 2 floor lamps plus 2 table lamps, or a bedroom-plus-hallway conversion, the 4-pack saves on per-bulb cost.

If you are trying smart bulbs for the first time and are not sure how many you will actually use or enjoy, start with the 2-pack. Upgrading later is easy. Having 4 bulbs and using 2 means two are sitting in a drawer.

Pros and Cons

Pros

  • Lower per-bulb cost than the 2-pack
  • Kasa reliability applies at any pack size
  • Economical way to convert a room quickly

Cons

  • Higher upfront cost because you pay for 4 at once
  • No feature difference from the 2-pack, just economics

Bottom Line

Buy the Kasa KL125P4 if you need 4 or more smart bulbs for a room or fixture. The per-bulb savings over the 2-pack are real at this quantity.
