Zoo Med LED strips are an excellent light source for terrariums. With a colour rendering index (CRI) of 94 and a colour temperature of 5000 Kelvin, they will allow plants to grow while bringing out the warm colours of the terrarium's inhabitants. A 6500 Kelvin light source gives a blue-grey rendition, while a 5000 Kelvin source brings out the reds, yellows and greens.
