Installation Instructions----LED Ceiling Panel Light
Installation Instructions
◆Installation instructions(See Installation diagram)
1. Fix the base on the ceiling using
screws.
2. Fix the light panel to the base
handler.
3. Connect the driver to the input
power
◆Note:
1. Cut off the power supply during
installation to ensure safety.
2. Must be used within the rated
voltage range.
3. No matter what the circumstances,
the light could not cover by heat insulation pad or similar materials.
4. If you have any questions about
our installation instructions, please ask a qualified engineer.
5. Do not disassemble the lamp without
our company’s permission.
6.
Do not switch the lamps frequently.
Surface Mounted LED Ceiling Light is your best choice for lighting of home,save your electricity bill,is the most cost-effective indoor Home light

Why the price of led lighting so different?
There
are so many factories to produce LED and LED lights,different factories will
use different quality materials,that’s an important reason of led lights’ price
so different.
Due to the increasingly fierce price war, even the
lamp’s appearance, structure and function is almost same, but the price
difference will be 2-3 times, so many users do not know what should be choosed
1. Lumens.
Different LED Brightness,then different price.
2. Anti-static
ability
Strong anti-static ability,then long life time,but in high price.Usually
more than 700V can be used for led lighting.
3. Wavelength
Same wavelength then same color,if you want them all in same color,then
price is high.Without color device,it is hard to produce pure color products.
4. Leakage current
LED
is a single direction of the light emitting, if there is a reverse current,
then known as leakage, large leakage current,then the life time is short,and
low price.
5. Beam angle.
Different
application,then should be used different beam angle,special beam angle, the
price is higher. Such as the diffusion angle, the price is much higher.
6. Life
time
Lighting decay is more fast,then life time is short,small lighting
decay,then long life time.
7. LED
Chip
Using different led chip,the price will be much
different.Japanese,United States’ chip will be more expensive,such as
CREE,NICHIA,Bridgelux.And other chip is
also good,such as SamSung,Epistar,the price is not so high,but stable
quality.And here,we are not talking about other cheap chip.
8. Chip
size.
Big chip will better than small chip,and the price of big chip also
expensive than small one.

HOW TO CHOOSE A GOOD LED LIGHT?
The LED lamp is mainly composed of 3 parts, aluminum shell,driver,LED.So you should pay attention to these aspects when purchase LED Lamp,then can buy the best cost-effective products.
1.Aluminum shell.All lighting products will generate heat when working,if the heat can not be timely export to escape, it will seriously affect the life of the LED lamp and lighting effect.So the aluminum shell is a very importance part of the lamp,and help to dissipate heat.Then what type of aluminum shell has good heat dissipation?First of all, the purity of aluminum,6063 aviation aluminum is the best choice, not only with beautiful appearance, and heat dissipation capability is strong.But for the large lamp,die casting aluminum also a good choice,so it must be composed of aluminum alloy, For the normal proportion of alloy, heat dissipation is no problem,but some people will add many messy impurities in aluminum alloy to reduce the cost.then the aluminum shell has very poor heat dissipation.So we need check the shell when buying,work fine and smooth shell may be preferred.At the same time,please also check the thickness of aluminum shell,too thin is not good.
(We always use good quality aluminum to make the products,no matter the workmanship and appearance are very good.At the same time,we also try our best to develop the lamp with lower heat.)
2.Driver.LED Driver is very importance part of the lamp,after all,the LED lamp is damaged mainly because of the driver.So you could ask the seller about the parameters of driver,such as output voltage and current,power factor, working temperature and so on.Working voltage of 1W is about 3.2V,Working current is about 320mA.If the current is too large,the lighting decay will very fast,and shorten the life time of lamp.If the driving power factor is too low, such as PF=0.6,then
will waste energy.At the same time, low power factor,heat of driver will increases,the electronic components are most afraid of is heated, the heating means of electronic components increase their own temperature,it is easy to appear quality problems.For Dimmable driver,good dimming effect driver is much expensive than normal dimming effect driver,normal dimming effect driver is unsatisfactory.So the customers need to be carefully considered when buying.
(Most of our led lamp were adopted High PF>0.9,Pass CE Isolated Driver Or Famous
brand MEAN WELL driver,and most of lamps were used normal non-isolated driver in the market,some drivers even don't have IC,at present,many factories use resistance-capacitance driver,but it is not safety and the lamp is very easy to stop working.Of course,the cost is very low.So the cost of good quality driver is much higher than bad driver.)
3.LED Chip.It is the heart of the led lamp.So it is better to choice famous brand led chip,they have high lumens and good CRI,long life time,no matter the performance and stability is guaranteed,at present,there are many brands of led chip,and some factories try their best to reduce the cost,such as using 0.5W chip instead of 1W,using copper wire instead of gold wire when making LED,that will save much cost,but in bad quality.
(We usually use CREE,Bridgelux SUMSUNG,SHARP,OSRAM,EPISTAR LED Chip,they are all famous brand chip and in high quality,we only use approved and real materials.Here,we should remind the customers,because there are many people said they used famous brand led but at very low price,it is not true,for example,1PCS 1-3W CREE led,0.5USD/PCS,adding the cost of aluminum shell and driver,for 3W led spotlight,if using real
quality
materials,the lowest cost even more than 4USD.So the customers need to be carefully considered when buying.)
