led module are made of Through hole led and super flux led and SMD LED and RGB LED.LED module is devided into waterproof and nonwaterproof.There are cool white nature white warm white blue green yellow ambler and red on aviable.Through hole led module have very competive price.Super flux led module have three view angles for your choice. 60 degree and 90 degree and 120 degree. Super flux led module were very popluar aroud the world from 2005~2008.But More and more signmakers prefer to choose SMD led modules as the cost go down and smd led modules have 150 degree.80% neon distributors gave up neon to sell led modules because of saving energy.LED module are mainly applied in light box and channel letter and signage.The most famouse led module supplier is GE and PHILPS and US-LED and Samsung and orsram and tridonic. But their price is very high .The quality is also awsome.Most of led suppliers come from Shenzhen China.They usually attand LED China exhibition.The pirce is very low.But you should be careful.Perhaps the quality is not good if you focus on price.So I suggest that you choose the led module suppliers who have more than 3 years' experience.Many suppliers shall tell you that the warranty is 3 years .50,000 hours span life.It is true lie.But As I know.The SMD LED Module can last 3 years if the quality is ok.you have to have to consider GE/PHILPS/SloanLED if you want the led modules can last 5 years.You have to consider the following items if you are going to order led module.The span life,the brightness and the view angle,the delivery time .There is one very important point you should know.The color temperature every order is different.You can not use white led module from different order in the same channel letter.you shall see different white color from acrylic.You clients shall kill you.According to my 5 years' led modules experiences.Signmakers prefer to choose better quality.But led module users from Asia such as vietnam india thailand are more sensitive to price than quality.Signmakers from Middle east such as iran and turkey choose super flux led module than SMD LED Module.Sigmakers from Canada and USA would like to choose led module with UL certificate.Europe sigmakers choose the led modules with CE and Rohs.As sales in LED module supplier's company,I know more and more suppliers choose worse and worse chip in led as strong competition and too low price.How to judge the quality the led?The size of chip.The best chip size of 3528 is 10x23 mil now.But I can tell you there is only serious suppliers offer this chip.And the price is more 30% higher than regular led module.But There is no so many troubles from your clients.AS I know.There are more than 300 led module suppliers in shenzhen.Well you can find 5 led suppliers in one building if you arrive Shiyan town Shenzhen city.And Here is very good hotel named Changfeng Garden hotel.4-stars. 40$ each night.You shall find about 50 led module suppliers with 500 meters of the hotel.By the way.I my opinion.Honest sales is very importat to help you find right led module
