How to choose and buy the LED flood light?

Note when buying:
1, led flood light luminance (MCD) is different, different prices, LED lamp more, the greater the brightness, natural price is not cheap, generally led lamp is a high technology products, in order to ensure the follow-up of the floodlight using in the process of stable performance, it is recommended choose the regular brand manufacturers to buy led flood light.
2, antistatic ability is also need to consider, antistatic ability of LED, its long life, and thus the price is high, usually more than 700V antistatic LED can be used for LED lighting.
3, the wavelength of the same LED, and thus the color is consistent, this kind of led flood light natural price is more expensive, if the requirements of the led flood light color consistent, then the price will be higher.
4, the leakage current is very important also, led flood light is a one-way conductive light-emitting body, if there is a reverse current is called leakage, the leakage current of LED, the short service life, slightly larger current there can be burned out bulb, so the price of this type of led flood light is relatively low, suggest it is best not to buy this type of lamps and lanterns.
5, light-emitting angle consideration, LED light-emitting angle is different, the lighting effect is not the same, the natural price is not the same as, general luminescence special point of view, higher prices, regardless of whether such a request you to buy led flood light, it is recommended in the purchase process is best to consider the factors.
6, the chip factor considerations, led flood light emitting body for the wafer, the different chips, the price difference is very big. Japan and the United States wafer is more expensive, generally in Taiwan and domestic chip prices below Japan, the United States (Cree), and chip size would affect the led flood light and general LED chip quality is better than that of the smaller chips.
7, colloid is a factor that must be considered in the process of led flood light purchasing, because this relationship to floodlight lamp service life long, general ordinary led colloid generally epoxy resin, and high-quality outdoor led flood light should be anti UV and fire, so with anti ultraviolet line and fireproofing agent led prices more expensive.
If led flood light is used for outdoor, it is recommended to choose the best option to add anti UV and fire retardant LED.

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light can form a

What ways can see LED street lights to replace the high pressure sodium lamp?

Image
Under the condition of current technology,luminous efficiency of  LED street lamp  is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort. Followed by "irradiation uniformity", although the  LED street lamp  lighting is relatively concentrated, but can be by the light path of the second design, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so as to realize the uniformity of illumination.

Rule of thumb: what are the installation instructions of DALI LED high bay light?

Image
DALI LED high bay light , also known as LED warehouse light, mainly used in factory workshop, warehouse, exhibition hall, etc., have gradually entered homes, because it is using the latest LED lighting energy saving technology, high reflectivity, high power, high utilization rate of light source. But good lamps and lanterns need specification installation, to highlight its advantages, below for everyone to explain the DALI LED high bay light installation: 1，Define DALI LED high bay light installation height according to the lighting environment, because the environment will change the reflection efficiency of lamps and lanterns. Usually the height of DALI LED high bay light  should be above 5 meters, thread is not close to the lamp shell. If installation height is less than 3 meters, protective measures must be taken to prevent a vehicle to touch. 2，TEK DALI LED high bay light protection class is IP65, choose waterproof transformer, chip packaging place with high temperature resi
