Exterior floor lights and spike lights, both LED and low-energy versions.
Spike lights are a precise effective way of lighting outdoor spaces, through focusing angles of the light beams onto the desired features. This provides a soft effective shine and lighting effect.
An extensive example of the use of small LED floodlights with the use spikes is the Eden Project in Cornwall. Spikes are used to uplight shrubs, palms and banana trees for a small selection of examples.
