Spotlights fitted within the planter can be angled up to illuminate large plants, bushes and trees several meters above the planter surface - this is referred to as "up lighting". LED emitters rated at 1, 3 or 5 Watts are equipped with 5, 15, 25 or 45 degree collimating lenses to send a narrow beam of white or coloured light to illuminate the chosen feature high above the planter. The layout of the planting can conceal the light sources to enhance the effect.
