DUSK TO DAWN
Sunco Lighting Dusk to Dawn LED lights includes a sensor to detect light levels at night. The Dusk to Dawn sensor turns on the LED when no light is detected at night then turns the LED off again when light is detected. Just power it on for the sensor to detect light levels and illuminate the night. All D2D light bulbs are designed for outdoor use only.
INFRARED AND RADAR PHOTOCELLS
INFRARED PHOTOCELL
Infrared photocell sensors are set off by either the heat from incandescent
lights or sunlight, not visible, ambient light.
Temperature can slightly affect sensor behavior. Our bulbs contain components
to help combat that. However, hot and cold temperatures may modify when a
light turns on: ·
- When the sensor is warmer, it may turn on a bit earlier.
- When the sensor is cold, it may turn on a bit later.
RADAR PHOTOCELL
Radar photocells (like the Sunco PAR D2D Bulbs and Wall Packs) are triggered
by sunlight or ambient lighting in the Visible Spectrum. They may turn off if
other light sources are detected.
VISUAL TIPS
The Dusk to Dawn sensor cannot detect whether it is light or dark when the light fixture is closed. In an open fixture, the sensor will detect light through the clear glass panes and turn on at night.
Even an open light fixture cannot function when hidden behind a tree or shrub.
Here, the light is on during the day, because sunlight is not reaching it.
If a Dusk to Dawn LED is installed too close to another switched-on light, the
sensor may be fooled into thinking the light detected is daylight. Since D2D
lights turn on/off automatically and do not require a timer to activate. Avoid
using them with a timer on the same circuit.
At night, the left D2D LED cannot turn on as there is no power. In contrast,
the D2D on the right has power and the sensor can function properly.
FOR BEST RESULTS…
Use at Night| Bulbs and fixtures with Dusk to Dawn technology only work at
night.
---|---
Use Outside| Dusk to dawn sensors are designed to be used outside to detect
light levels of the sun.
•A commercial exception: Use Dusk to Dawn bulbs in retail or shop window
displays for automated lights
Avoid Reflections| Dusk to Dawn sensors detects light. Make sure the sensor
does not face reflective surfaces. Reflections can mimic sunlight. Avoid
placing sensors near windows, glossy walls, and shiny floors.
Other Light Sources| Dusk to Dawn LEDs cannot tell the difference between sun
rays and bright light, they just look for light levels. If a bright light is
detected, the light will not turn illuminated.
Spacing Dusk to Dawn| To avoid sensor interference:
•Space your Dusk to Dawn bulbs at least ift (30 cm) apart
•Avoid placing more than 1 bulb in the same fixture
Leave the Switch On| All Sunco Lighting Dusk to Dawn LEDs requires power to
operate. Turn on the light switch after you screw in the Dusk to Dawn LED
bulb. The built-in sensor will then turn on the LED when light is absent and
off when light reappears.
No Timer Needed| Dusk to Dawn LEDs will automatically turn on when no light is
detected by the sensor and turn off when light returns. They are not
compatible with dimmers or timers.
Recessed Cans| Use dull trim inserts or cans that are not reflective inside
the recessed can. This will avoid strobing/flashing issues.
Covering and Blocking| If the (visible) sensor is covered or blocked, it
cannot function correctly to detect light levels. Either it won’t turn on or
it will stay on 24/7.
Includes:
•a solid light fixture where the housing blocks the sensor
•a shrub, bush, or tree
•the frosted or darkened glass pane of a light fixture
•placing fixture inside an alcove where sun cannot reach
•the sensor facing away from potential light sources
Choose Open Fixtures for PARs| PAR LED Bulbs with Dusk to Dawn should not be
used in enclosed fixtures (even with clear glass panes) as the bulb could
overheat or impact bulb lifespan.
Suggested applications for PARs:
•Dual spotlights (under a roofline or above a garage door or other doorway)
•Landscape or signage uplights
•Open wall sconce
•Recessed cans
