FAQs for Demax LKH Series Solar Street Lights
1. What core configurations does the Demax LKH Series solar street light include?
The LKH Series adopts an all-in-one integrated design, featuring 18V monocrystalline silicon solar panels (50W-150W based on models), high-quality Lithium LifePO4 batteries (231Wh-960Wh), and 4-core high-efficiency SMD 3030 LEDs (96pcs-336pcs). It is equipped with an MPPT controller for optimal energy conversion, and all models meet IP65 waterproof and dustproof standards, with a solar panel conversion efficiency of 23.8%.
2. How long can the LKH Series maintain lighting during rainy days?
The lighting duration without sunlight varies by model: the 30W model supports 2-3 rainy days, while the 40W, 60W, 80W, 100W, and 120W models can operate continuously for 3-5 rainy days. All models provide 12 hours of stable lighting per night, ensuring reliable performance in areas with frequent rainfall.
3. What lighting control modes are available for the LKH Series?
The series integrates three intelligent control modes: microwave induction, segmented time control, and auto on/off (dusk to dawn). Users can set the modes according to actual needs—for example, the motion sensor triggers full brightness when detecting movement and switches to energy-saving mode when inactive, balancing lighting effects and energy efficiency.
4. What are the recommended installation heights and pole adapter specifications?
Installation heights are tailored to different powers: 5-6m for 30W, 6-7m for 40W, 7-8m for 60W, 8-10m for 80W, 10-11m for 100W, and 11-12m for 120W. The optional pole adapters are 65mm and 76mm, compatible with most standard utility poles, and support pipe-mounted or arm-mounted installation without additional wiring.
5. What is the lifespan and warranty of the Demax LKH Series?
The LED components have a lifespan of up to 50,000 hours, and the Lithium LifePO4 battery supports 2,500+ charge cycles (6-8 years of service). Demax provides a 3-year official warranty—for product quality issues within the warranty period, the company covers the shipping costs for repairs or replacements.
6. Are there quantity-based price advantages for bulk orders?
Yes, the series offers tiered pricing: sample quantity (less than 50pcs) at standard unit price, bulk price (50-500pcs) with preferential discounts, and additional concessions for orders above 500pcs. Quotations are EXW terms and valid for 30 days; bulk order delivery times are negotiable, while samples are typically shipped within 3-5 days.
7. What are the key structural and material advantages of the LKH Series?
The radiator is made of 6063 aluminum + ADC12 die-cast aluminum with thick anti-corrosion spray paint, ensuring excellent heat dissipation and rust resistance (passing 1,000+ hours of salt spray testing). The battery is removable for easy maintenance, and the high-transmittance PC lens (light transmittance >95%) enhances lighting efficiency. The all-in-one design eliminates trenching and wiring, reducing installation costs.
8. Which certifications has the LKH Series obtained, and where is it applicable?
The product has passed multiple international certifications, including CE, ROSH, IEC60598, IEC62722, LM79, LM80, IK08, wind resistance test, and anti-corrosion WF2 test. It is widely suitable for municipal roads, rural highways, parking areas, public squares, resorts, and other outdoor lighting projects, and can adapt to harsh environments such as coastal or high-humidity regions.
