Fasten under hand-railing or on bollards.
Can't see the lamp? That's the point! We should see the illuminated area and not the light source. This ensures there is no glare or light trespass across your neighbour's property. It comes with a versatile mounting bracket for a different mounting configurations, and the EcoLight-D has the adjustable-brightness feature to suit a wide range of applications.
The EcoLight is mounted at 1-meter high and spaced at 5X the mounting height. Competing fixtures may be cheaper but may require a luminaire every 1-2 meters, so the EcoLight system-level cost will be much cheaper, and uses significantly less power. Seeing the treeline and the stars gives pedestrians a sense of place and helps in navigating the area.
- Won't affect circadian rhythm or undermine health
- Eco-friendly amber for low ecological impact
- No glare for pedestrians
- No light trespass
- Minimal backlight
- Light only where it's needed
- "Along-track" illumination ~ 5-mounting heights with no "Bright Patch"
- "Across-track" illumination ~ 1.5-mounting heights
- Low energy use for size of target area
OTHER LIGHT FIXTURESWhite Light
- Disrupts the biology of plants and animals
- Exacerbates impacts of glare and light trespass
- Glare for over hundreds of meters
- Poorly defined target area
- Sprays light where it is not needed
- Light trespass impacts plants, animals and human health
"Bright Spot" Illumination
- Limits visibility to only centre of beam
- Prevents visibility into periphery
- Small illuminated area for a given power
Requirements change over time. Need to re-purpose the luminaire? No need to buy a different fixture. Mounting the EcoLight higher above the path and adjusting the illumination level turns it into a low-impact streetlight!
In this image, the EcoLight-ECONOMY is mounted over a doorway. Sharp cut-off shielding prevents glare and light trespass from bothering neighbours.
At a height of 4-meters, and power set to 4.3-watts, they do a fair job of marking the road to the rural property. There is very little back-light into the bushes and the forward light is limited to the immediate area.
For this image, the EcoLight was spaced every 24 meters (6:1) with a uniformity of about 3.5 so you need fewer poles and fixtures than with most other luminaires, and you will use a lot less power.
The white light prevents our night vision from seeing anything but the illuminated patches on the roadway. Without the treeline, we loose our sense of place and the security it provides.
It's very pleasant to sit out on a summer's night talking with friends or reading a book. But white light attracts mosquitoes, and it ruins our night vision. The EcoLight helps preserve our night vision and it doesn't attract bugs as much as white light.
Here, the EcoLight is mounted about 2-meters above the ground, and the brightness is set to the limit for reading (less than 1-watt). At this brightness the colour resembles candle light. And yes, you can still see the stars. But with white light, your night vision is reduced - you can't see beyond your small pool of light.
Lighting ScheduleThe Ecolight-Deluxe comes with a controller to schedule the illumination throughout the night to minimize its ecological impact during periods of greatest sensitivity, and to conserve power.
Below is the default timeline. It ramps-up to the user-set brightness at sunset. You then set it to dim when you no longer need the light. Typically this is about 22:00-23:00 when vehicle and pedestrian traffic is low.
It then dims to the user-set brightness level for the rest of the night. At dawn, the EcoLight-D automatically turns off.
You can brighten the light for a few minutes during the Dim Time by "flicking" the light switch in the building, or using the Smartphone APP.
Using your Smartphone (iOS or Android), the maximum and minimum light are user-adjustable over a range of more than 200:1 for about 5-lux at 6-meter height for roads and down to <1-lux at 1-meter height for pathways. And, the dim-time can be changed over a range of more than 3-hours to suit your specific needs.
Photometrics [IES LM-79]The photometric plot below for the EcoLight-D is based on the maximum power of 7-watts, 6-meter mounting height. The EcoLight-E is about 1/2 the power and brightness.
The EcoLight has a wide light distribution that allows a spacing of about 4x Mtg.Ht. with a uniformity of roughly 3:1 [Max./Ave.].
The illumination is "forward" minimizing backlight (behind the mounting point). This means a supporting arm is not needed to place the illumination pattern near the centre of the target area - saving installation costs and visual clutter.
Virtually no light shines beyond 12m on each side or 6m across the target area. This ensures essentially no glare beyond the target area, but allows a gentle merging of illumination when EcoLights are combined into a string for pathway and roadway lighting.
