Luminous Efficacy 130 lm/w.
Light effect= luminous efficacy.
LED lamps have a long service life and excellent luminous efficacy.
High luminous efficacy of>110 lm/W.
Also produces light with higher luminous efficacy and color temperature.
One of the key advantages of LED-based lighting sources is high luminous efficacy.
Theoretical maximum luminous efficacy of white LEDs.
In comparison with incandescent light bulbs,neon lamps have much higher luminous efficacy.
Samsung led chip, Higher LED luminous efficacy: 140lm/w Longer lifespan.
In general, the higher the leds luminous efficacy and color rendering index is lower.
You can see the wattage is dramatically reduced after retrofitting the MH because LED has exceptionally high luminous efficacy of 140 lumens per watt.
Therefore, the overall luminous efficacy LED street lamp is stronger than the high-pressure sodium lamp.
The power of these ceiling fixtures is 42W, and their luminous efficacy is 2700 lumens.
Luminous efficacy can be normalized by the maximum possible luminous efficacy to a dimensionless quantity called luminous efficiency.
Luminous intensity candela cd luminous efficacy of a 540 THz source same as current SI.
But simply»filling« the spectral distribution with further wavelengths in the visible field(380- 780 nm)will lead to a drop in the theoretical maximum luminous efficacy.
Light source: 40W Bridgelux LED characterized by high luminous efficacy, high brightness, low deprecation, long life and more.
The overall luminous efficacy of a source is the product of how well it converts energy to electromagnetic radiation, and how well the emitted radiation is detected by the human eye.
To achieve this, all of the lights use advanced LED technology- with high luminous efficacy and low power consumption.
In 2018, we upgrade the optics so that the luminous efficacy raised to 140 lumens per watt, which is 8 to 12 times of halogen bulbs.
Depending on the type of plant being cultivated, the stage of cultivation(e.g., the germination/vegetative phase or the flowering/fruiting phase), and the photoperiod required by the plants,specific ranges of spectrum, luminous efficacy and color temperature are desirable for use with specific plants and time periods.
Light with wavelengths outside the visible spectrum reduces luminous efficacy, because it contributes to the radiant flux while the luminous flux of such light is zero.
The average luminous efficacy of LED luminaires will certainly continue to improve since there are luminaires on the market with a luminous efficacy of 50- 70 lm/W which can still be optimized.
Lamps of this type are widely used forlighting facilities,have a high luminous efficacy of 50-70 lm/ W, low heat radiation and long service life.
Metal halogen lamps have a high luminous efficacy at around 75-100 lumens per Watt, which is about twice the efficiency of mercury lamps and 3 to 5 times the efficiency of incandescent lamps.
With a thermal test of 85°C,a color temperature of 3000K, and an index of 80, the luminous efficacy can reach 150LPW, which can be used in many indoor lighting applications.
Metal-halide lamps have high luminous efficacy, about 75-100 lumens per watt, which is about twice the efficacy of mercury lamps and 3 to 5 times the efficacy of incandescent lamps.
A common shortcoming of incandescent lamps isabsence in their spectrum of blue light andtoo low luminous efficacy of 17-25 lm/ W, and so for the lighting of plants, they are not very suitable.
The main difference between the luminous efficacy of radiation and the luminous efficacy of a source is that the latter accounts for input energy that is lost as heat or otherwise exits the source as something other than electromagnetic radiation.
