Environmentally speaking, the solar bollard Generation 2 is low light pollution and light waste, with the least disruption to the immediate ecosystem. These environmental parameters are achieved with the soft natural white light (~4,000K), that the LED optics direct light downward where it is needed, and, the LEDs are in an asymmetric arrangement (no back light). In some cases, where wildlife may be disturbed, a warm white colour temperature (~3,000K) is requested. For areas that are right in line with breeding areas for turtles, a 605-620nm is available.
