If you have cabinets smaller than 12", which are not wide enough to install the standard 12" light bars from Litever LL-008 series, you can use those 6" light bars there.
Pls read the “Recommended Layout” part of the LL-008 User Manual to decide the maximum light bars you can add to LL-008 Series.
The Litever 6-inch light bar for under cabinets is intended for compact storage units. It works seamlessly with the Litever LL-008 Under Cabinet Lighting Set.
