1. A lighting device, said device including:
- a lens;
a circuit comprising;
at least two light sources of different colors mounted to direct light through at least part of said lens;
an activation sub-circuit to provide power to said light sources only at low light levels;
a light sub-circuit to independently control delivery of power to each of said at least two light sources so as to ramp up and ramp down intensity of light emitted over time by said at least two light sources to produce a color changing cycle of more than two colors;
connections for at least one rechargeable battery to power said circuit; and
at least one solar cell mounted so as to be exposed to light and operatively associated with said connections to charge said battery.

Abstract
A garden light (10) having a body (11) with a post (12), the lower end of which is provided with a spike (13). The upper end of the post (12) receives a lens assembly (14). Secured to the lens assembly (14) is a cap assembly (24) that has three LEDs that are activated to produce a varying color light.
