BOLLARDS : THE BRIGHT WAY TO LIGHT PATHWAYS

FUNCTIONALITY , AESTHETICS , AND ENVIRONMENTAL CONSIDERATION
Bollard lighting has emerged as a popular choice for illuminating pathways and landscapes . Today , there ’ s a far greater variety than ever before , and finding a design that matches the scheme in terms of material and light output has never been easier .
The growing trend of ‘ Dark Sky ’ compliant lighting is helping to push this change . Factors such as colour temperature , light spillage and gradual dimming are now being considered in schemes as important specifications . Bollard lighting has fast become a very appealing option for lighting responsibly , with many robust designs available . Lumena has developed fixtures around this trend for years , both mains and solar powered . Many of these light fixtures are as functional as ( or more in some cases ) conventional fittings , whilst highly reducing the harmful impact of artificial light on humans and nature .
Stopping the Spread First and foremost , let ’ s talk about the spread of light , particularly , directing light towards the floor . Light can be damaging if not thought through . In urban spaces , light entering into residential or commercial windows is harmful , and in rural areas artificial light can disrupt the behaviour of nocturnal wildlife . Most bollards have a fixed downward LED panel or a louvred head to reduce glare . Louvres direct light downwards , away from delicate areas , shielding the sky above .
A Warm Welcome Contrary to popular belief , warm white (< 3000K ) and daylight white (> 6000K ) LEDs produce roughly the same output . Daylight whites appear brighter to the eye because the blue light scatters more . As a general rule , warmer tones ( below 3000K ) is the least disruptive kelvin range to wildlife . In more sensitive areas , below 2700K is advised , moving into amber territory . From summer 2024 , Lumena ’ s Eccentrica solar bollard will be available in 2500K , which is comparable to traditional incandescent lamps .
The Not-So-Dim View Whether it be in urban or rural areas , rarely does public lighting need to be at full brightness all night . Light is needed most during busy periods , usually shortly after dusk . Lumena ’ s Pro Solar bollards gradually dim down from 100 % to 30 % throughout the night . PIR sensor bollards have a similar effect , only illuminating at full brightness when triggered by passersby .
Bollard lighting for pathways offers the opportunity to create a blend of functionality , aesthetics , and environmental consideration . By embracing downward-facing lights , warm color temperatures , and dynamic dimming , we can create pathways that are not only safe and inviting but also respectful of the delicate balance of nature .
