Q3:Can you provide customized services?
Yes, we can provide one-stop solutions, such as: ODM/OEM, Lighting solution, Lighting mode, Logo print, Change Color, Package Design,Please inform us formally before our production
Q4. What is your terms of payment? 
A:Usually, we accept T/T,irrevocable L/C at sight.For regular orders, Terms of payment 30%deposit,full payment before delivery the goods.
Q5: How many products are there for me to choose?

Q6: What about the lead time?
A: 3 workdays for sample, 5-10 workdays for batch order.
Q7: Can the solar street lamp be used in high&low temperature area and strong wind environment?
A: Of course yes, as we take Aluminum-alloy holder, solid and firm, Zinc plated, anti- rust corrosion.
Q8: What's the difference between Motion sensor and PIR sensor?
A: Motion sensor also called radar sensor, works by emitting high frequency electric wave and detecting people movement. PIR sensor works by detecting environment temperature changing, which usually is 3-8 meters sensor distance. But motion sensor can reach 10-15 meters distance and be more accurate and sensitive.
Q9: Do you offer guarantee for the products?
A: Yes, we will provide professional after-sales service
The industry standard warranty period is 2 years. But we offer 3-5 years warranty to our products., during which we will provide related after-sales service free of charge. The lamp can still work normally after 3 years of normal use.
