Q:How much ballast does the LED 15W lamp belt need?

The key is the light effect of LED. Light effect LED beads are currently available from 40LM/W~100LM/W, see what you buy. Incandescent light effect is about 10LM/W, LED whole lamp, if it is cheap Zhongshan goods, it is estimated that 30-40LM/W, okay, you can go to the 60-70LM/W, PHILPS light Expo in the sample displayed, you can go to 90LM...The LED lamp uses a constant current source, not a ballast, and the output power of the constant current source should be greater than 100W, and the specific value depends on the setting

Q:The advantages and disadvantages of LED and solar garden lamps

LED courtyard lamp structure is simple, maintenance is simple, and not easily affected by battery life. Generally installed, you can use more than 10 years.

Q:Courtyard lamp installation requirements are?

The solar garden lights which use solar energy resources, we can learn that it's clean is very powerful, but there is a light source it is using low voltage LED light products, making itself have an advantage, because it does not contain mercury, light and not for glare problems. Therefore, the development of solar garden lamps in recent years is quite acceptable.

Q:Why lawn lamps are gradually replacing traditional courtyard lights?

Although lawn lamps and garden lamps are garden decoration lamps and lanterns, but no one can replace who, the effect is different, can only say from the material, light source, innovation.

Q:LED how much is the color temperature of the courtyard lamp?

If there is a moonlight at night, then warm and white, with the moonlight around you, will enhance the overall color hierarchy of the courtyard.If the garden is unique to you, warm white is a good choice.

Q:How much is the installation of the courtyard lamp?

Depends on whether you have to pull the wire, if only to dig the foundation installation, a light salary of about 150, but also depends on the number of installed.About courtyard lights, I hope I can help you, please adopt.

Q:Garden lamp installation project quotation template

The LED light source characteristic of solar street lamp has:1 、 high luminous efficiency, small power consumption, long service life and low working temperature.2 、 safe and reliable.3, the reaction speed is quick, the unit volume is small, green environmental protection.4, the same brightness, the power consumption is 1/10 of incandescent lamp, fluorescent lamp 1/3, and the service life is 50 times that of incandescent lamp, fluorescent lamp 20 times, is the fourth generation lighting products following the incandescent lamp, fluorescent lamp, gas discharge lamp.

Q:How much is the solar garden lamp?

Finally, some LED streetlights do not heat well:The 1.LED light source has great thermal resistance, and the heat of the light source can not be dispersed. The use of heat conductive paste will cause the cooling movement to fail.2. using aluminum substrate as the PCB connection light source, because the aluminum substrate has multiple thermal resistance, the light source heat transfer, the use of heat conductive paste will make the heat dissipation movement failed.3. no room for the light emitting surface of the thermal buffer, LED light source will cause heat failure, failure in advance.

Q:Brand solar garden lamp which is good?

Depends on what brand does not shape, the market depends on the use of solar panels, monocrystalline monocrystalline silicon power generation panels, relatively look at the battery, storage battery to choose the brand, its main inverter selection of monocrystalline silicon, mainly to see the photoelectric conversion rate higher

Q:Is the LED courtyard lamp cold?

How many degrees below zero are you? Have you ever seen a duck cold? Ha-ha
