What will we serve for you?
Believe us,we are the most professional!Evaluations will be customized for you according to the process below:
Q1.What is your main product line is made?
We mainly produce led industrial lighting fixtures application classes and induction lighting fixtures.
(led street light, led high bay light, led flood light, led downlight, led tri-proof light,led gas station light,more.)
Q2.Are you factory or trading company?
We are a factory, we provide OEM services. Some famous foreign supermarkets and we often collaborate.
Q3.Does LED high bay light really have 50,000 hours lifespan?
50,000 or longer lifespan is only theroy from lab test.But due to working enviroments are different from in lab,actual lifespan is only ≥30,000hours.
Especially for LED high bays and LED floods,the power is very huge,and lots of heat cause LEDs junction temperature very high.And light decay will be higher than low power LED products.
If the led lights can work well 24/7 days without power off,and still work well in 5 years,
the lights are very good.That is why the warranty in the market are mostly 5 years.
Q4.For same power,why different suppliers with different brightness?
Different chips,or same chip but different brightness version.The brightness will be different.But for same chip and same brightness version,the brightness will be slight difference.But please make clear the difference between LEDs and lamp fixture.
For example,50W LED flood light,bridgelux 110-120lm/w LEDs,the LEDs brightness will be 5500-6000lm.But the LED flood fixture will be only around 4100lm.Please note.
Q5:What is PF and efficiency?
PF and efficiency is to feedback the driver electrical performance.Higher PF and efficiency with higher cost.
Q6:What is CRI?
CRI is a figure which feedback the real objects colors.Higher CRI with higher cost.Generally,LED flood and LED high bays,if they are made by epistar or bridgelux chip,the CRI are all around 70-75Ra.If this figure higher than 75,please ask your suppliers to send test data.Because there are some suppliers write a high data to attract clients but actually,the figure is even lower than the market.
