Not all large lighting brands LED bulb are of high quality. Hong Kong Consumer Council and Electrical and Mechanical Services Department (EMSC) found large disparities in energy efficiency and lifetime performances in 10 types of LED bulbs, among these included products from leading lighting brands. Differences in LED bulb efficacy reached 100%, while one sample burned out and lumen depreciation in certain products occurred at 10% mark of the product’s lifetime. A couple other products failed to pass safety tests. Consumers were advised by the council to choose LED products cautiously.

The council found Panasonic, Ledus, LKKM, Sunshine and IKEA bulbs luminous depreciation declined more than 5% after 3,000 hours of operation, and failed to meet EMSD voluntary energy efficacy label demands, according to a Wenwei Po report. Out of these, Hong Kong LED manufacturer, Sunshine’s, average luminous depreciation reached 30%, about 90% below the advocated 30,000 hour lifespan. The company’s pro…

Why are so many Chiese consuming foreign brands infant milk powder.

In 2004, fake Chinese-made baby formula that contained minimal nutrition caused at least 12

deaths and malnutrition for hundreds of infants. After that, foreiggn brands infant mil

powder getting more and more popular in China even price much higher. According to the

survey, foreign brands now account for half of all infant milk powder sold in China.

According to the report, the price gap send mainland parents flocking to Hong Kong and

Macao to stock up on foreign-produced milk powder.  A reporter saw a mainland customer

pulling a shopping trolley intended to buy 20 cans of milk powder, but salesclerk asked him

to get only two cans for "there's only a little stock left.". Some supermarkets in Hong

Kong have enatd safeguards such as limiting each customer to no more than three cans of

formula at a time.

LED corn bulb and high bay light

LED corn bulb and LED high bay light The most comment classical high bay and low bay lighting bulb are usually consider to use Mercury Vapor Lamps, Metal Halide Lamps, and Incandescent bulbs. Usually consider to extra high power 75Watt-400Watt. TEK Lighting Manufacturing special designed LED corn bulbs which could replacement Compact fluorescent lamps directly, and also it is the idea solution to replacement sodium lamp, mercury Vapor Lamps, Metal Halide Lamps, and Incandescent bulbs, so people also call LED corn bulb as E40 LED high bay light  or E40 LED high bay lamps.

LED high bay light- The best lighting solution for high ceiling application.

LED high bay light- The best lighting solution for high ceiling application. The principle of heat dissipation for TEK LED high bay light-- High performance heat pipe with aluminum fins. The heat-pipe’s principle is using the quick phases change the liquid(medium) under vacuum condition which exchange the heat, the heat transfer rate is superior to any metal.By Riveting the heat pipe to the aluminum fins, the heat pipe can conduct heat rapidly from chips bottom to the fins, greatly lower down the temperature of LED light source, extending it’s lifespan Why use heat pipe designed heat sink for LED high bay light? Before that, we study the thermal management of high-power LEDs. Most of the electricity in an LED becomes heat rather than light, high power LED transforms 20%-30% of electric energy to light and more than 70% of electric energy has been transformed into heat. Moreover, if use a build-in driver, the wastage of driver also adds the heat of LED. The accumulation of heat makes t…

IP65 LED flood light waterproof test

You have see some LED light indicates Protection Grade: IP65. But what is IP65, you my asking what does it means?

The IP code, international protestion marking, IEC standard 60529, sometimes interpreted as Ingress Protection Marking.

Behind the IP of 1st number stand for level of protection against solid object, and 2nd number is show level of protection against liquids

1. For the solide object:

E.G. IP65, we can see from above chart, number-6 is Protection against dust-- no ingress of dust; complete protection against contact. 2. For the liquid project: Protction against liquid: 5 Protection against low pressure water jets-- Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects. (More detail about IP Code, could refer to http://en.wikipedia.org/wiki/IP_Code) If you see the LED lights indicates protection grade IP65, that mean you can use in a heavy dusty and wet environment such as swimming center lighting.

What wattage LED corn bulb could replacement 150Watt Metal Halide?

Lets's study from a shop lighting project in Australia

They used Osram HQI-E 150Watt metal halide before. We can see from the Osram specification, 150Watt luminous flux up to 11,500lumens

What wattage LED we can use? 50Watt. Shop owner want a higher level brightness in the shop, so he purchased one sample 80W LED corn light with 6000Kelvin to test. from the picture you can see, 80Watt LED install on the right, We can see the price $11.35 on the price lable clearly. But another side below the MH bulb, FEVER. NICE....it is a little difficult to see the words...

 Obviously 80W LED corn light much more bright than metal halide.
so they retrofit 150Watt Metal Halide by 60W LED bulb. Now we can see the goods display on the shelf clearly.
