FEATURES

Equipped with dual ingenious daylight sensors, the SINCELIGHT® LED Sensor Light automatically lights up in darkness and turns itself off when the daylight is ample. It reduces electricity costs and investment on costly security lights. With its classic shape in a compact design, it delivers desirable lighting performance, making it ideal for general outdoor lamp fittings.

OPERATING INSTRUCTIONS

Turn off power before replacing, And just leave the light switch on as it will turns ON/OFF on its own according to the daylight level. For best performance, Please don't cover or block the sensors, And make sure there are not incandescent or halogen luminaries around, as that includes a portion of wavelengths and may interfere the sensors.

APPLICATION

This bulb is a widly applied for porches, garages, gardens, bulkhead, balcony, lawn light, wall light, pillor light, droplight, pole light and other outdoor lamps.with common E27 base that lets it be used with all E26/E27 socket lighting fixture.

ATTENTION

1. Don't install in any conditions that might cover or block the daylight sensors. The bulb will stays on when it can't detects enough daylight. For better performance, Please make sure more than one daylight sensor was in direction of the strongest daylight.
2. The bulb never lights up when the daylight is ample, To check the sensor function, please cover the bulb in darkness and then expose again, The bulb is normal if it turns off and then turns on again.
3. Not suitable for use with dimmers, emergency exit fixtures, emergency lights, photocell lighting fixture and any other fixtures included additional circuits.
4. Suitable for totally enclosed or airtight luminaries or fixtures, but there will be a certain percentage of lifespan reduction in this condition.
5. Requires IP65+ weather protective fixture for outdoor use.
6. Not recommended for indoor use, as the daylight level is unstable in this condition.
7. The bulb may stays on in bad weather conditions, including but not limited to rainy, snowy and cloudy days.

PROHIBITION

The product is strictly prohibited to be used in these conditions :
a. For fixtures and circuits with dimming functions.
b. For fixtures with internal control circuits.
c. For mercury vapor lamps or HID lamps.

COLOR TEMPERATURE

The colour temperature of a light source is taken from the temperature of a perfect black-body radiator that radiates light of a similar appearance to that of the light source. It is measured in units of absolute temperature; Kelvin (K). Interestingly, although red is associated with being a hot colour and blue a cold one, on the black body curve, blue occurs at higher temperatures than red. A more visual example of this apparent colour temperature contradiction can be seen in candlelight, which emits a warm red orange glow, but in fact has a low Kelvin temperature of 1850K. Therefore higher colour temperatures (5000K more) are called cool colours (bluish white); lower colour temperatures (2700 – 3000K) are called warm colours (yellowish white to red).

Colour Rendering Index (CRI)

The Colour Rendering Index (CRI or Ra) is a quantitative measure, which rates a light source’s ability to reproduce the colours of objects faithfully. In order to objectively compare the colour rendering properties of any light source, the CIE’s standardised measuring method operates on a scale from 0 to 100 (poor to excellent). The colour change of 14 standard colours is calculated when an object is exposed to a specific light source and then this is compared to a reference illuminant of the same colour temperature (a black body* is used for colour temperatures up to 5000K and daylight above that). The CRI for a pair of light sources can only be compared if they have the same colour temperature.

The CRI scale is chosen so that an ideal black body source, such as incandescent or halogen lamps, is by definition a CRI rating of 100. For light sources emitting a discrete spectrum, like LED and discharge lamps, the CRI can be anywhere between 0 – 100. As a rule of thumb, the more the spectrum is filled at all wavelengths (380 – 760nm), the better the colour rendering properties of the source, however a high CRI measurement intrinsically means lower efficacy (as less efficient wavelengths are also represented in the spectrum).

* A black body is a theoretical object that absorbs all incident electromagnetic radiation and due to its ability to absorb at all wavelengths, is the best possible emitter of thermal radiation. It radiates a continuous spectrum that depends on the body's temperature.
