imagine 7 series is linear RGB led strip where you expirence high quality red/green/blue light thus providing more enhanced led strips feel in your large space with excellent efficiency for LEED and othe energy conscious applications. they are tailor-designed for cove and other discrete applications where the light source/fixtures are typically completely hidden and only the light produced is visible. though long lengths are often desired, the led strips are engineered to be quite flexible and can be cut (“min. cut length”) to small sizes and spliced in the field without light leaks, shadows, or dark spots.
