19. After Market
Everyone can’t promise their products no problem in lifetime. We can’t
promise our products don’t have any problem in lifetime,too. However, we
can promise if our products has problem, we can give the solution
perfectly, repair, return the goods, change new products, if only you need,
tell us, we will undertake if our responsibility.
21. Market Information&Suggestion
1: Advantages of LED bulb VS Incandescent and Energy-saving lamp
2: Big market for LED bulb with prohibition of traditional incandescent
2.Pls consider below points when you choose LED Lights:
1: Good driver, quality LED and effective heatsink are the 3 most important components for good LED lamp.
Check if the driver use good quality Electrolytic Capacitors that ensure long lifespan, eg BERYL is
the top brand of China’s capacitor which ensure 8000Hs constant working at 105°C.
Check if the heatsink good at heat dissipation or excellent in air and heat convection, good heatsink can lower
lamp temperature to ensure long lifespan.
Check if use reliable LED, eg famous brand Cree/Semi/Everlight/Lumenmax/Samsung LED with high brightness,
good CRI and lower decaying.
2: Actually, there are different price for a similar appearance LED lamp, poor quality products will bring potential
quality complains even safety worriness, supplying interruption etc.
22. Suggestion to start and push LED business
1: Study your target LED lighting market and find your marketing direction.
Indoor LED bulb light and spot are big market with forbidden production and selling of traditional lamps in
many countries.
2: Make a website or B2B channel to promote your products.
Keep good contact with local property developer or government official or hotel owner, they can help you
win big project for they are richer and value energy saving.
3: Work with a reliable supplier (good quality, good services in technic and after-sale) and aim at long-term
mutual cooperation.
Market Information&Suggestion
23. Market Report: Why LED Light Factories Close For Low-Priced War?
• I take Zhongshan for example
• Zhongshan grew from small household appliances factory base into bigger LED industry
• Zhongshan is a city with decades of experience in the production of small household appliances, it becomes from earliest
production of rice cookers, kitchen supplies to development of LED industry in recent years.
• In 2012, Zhongshan LED lights enterprises over 1200, the output value of nearly 100 above-scale enterprises reached 35.65
billion RMB. Zhongshan LED applications enterprises ranked second in Guangdong province, accounting for 17.2% of the
province, accounting for 11.5% of China (Shenzhen account for 53% of the province).
• In first half of 2013, Zhongshan’ export value reach $ 570 million, South America and Middle East is the fastest growing
markets, respectively 22.4% and 19.5%.
• Very easy to open a factory and become a boss here
• Now you can buy all LED products-related accessories as you want here, this makes the threshold to enter LED industry is
very low, anyone can easily open factory and become boss here and make fast money here (fast cash into and cash out).By
rent a plant (cheap to ten dollars/m2), buy a few irons, purchases the needed accessories from the town, can finish simple
assembly at home, everywhere you can see such workshops enterprises, some have signboards, some not have any
identification, more than 60% of registered licenses are family-based small business owners.
• Many factories close for low-priced war---Price "is no minimum, only lower."
• A LED light factory giant(Chinese name 雄记厂)story can teach us a impress lesson(its annual sales reach 1 billion RMB)
• In July 5, 2013 雄记厂closed, the news of the boss escape factory boarded the major
• Headlines, major 3 reasons for their close:
• First, they offer very low prices to quickly occupy the market share.
• Take E27 3W LED bulb for example, the normal price of 3USD or more, they offer price is only 1.8USD, which lower than its
cost, and the bulbs broken only after 20 hours. In long term, in this way of offer lowest price, its sales volume rise rapidly but
the image of the product quality continuously damaged, eventually trouble into sell at lower price and don’t want to make
good quality to survive.
• Second, sometimes they cheat client by reducing production process and use inferior material, eg customer require 1W LED,
they make 0.5W to cheat customer to earn high profits. Blind pursuit of short-term benefits and regardless of quality and
provide low-end products beat themself finally.
• Third, the boss of their own mistakes and selfish policy. All the important positions in product design, manufacturing,
finance etc are all owners relatives, and they only get money but do nothing.
