Frequently Asked Questions or FAQs.

In this section, you can find the basic answer to most common questions.
Topics on Online Store, Terms & Conditions, Policies & etc...details..

Warranty
Our first priority is quality and reliability. We are very confident of our products, that we give ONE YEAR WARRANTY for all our products, including Compact Fluorescent Lamp.

We are the FIRST manufacturer in the world to provide this warranty for all our products, including the Energy Saving Compact Fluorescent Lamp.

 

Why is our price so low?
There are three main reasons why Luxeon's products are cheaper here than any other online store.

1. The birth place of Luxeon is in Malaysia. They are manufactured here in the Penang Island.

2. We are not here to make huge profit from our customer. As most of our customers are hobbyists, designers, engineers, we try keeping the price low to support the people. We just want to cover the cost for the service provided.

3. We are proud to be known as A Lighting Company with a heart. We do not focus only on Accounting Profits, but Social Profits as well. Click here for details.

 

Shipping Policy
We usually ship the order same day if receive before 1:00 pm or the next day, if we have the ex-stock. As we use world-class international, you'll receive your order within the next two days after we ship out.

 

Who's our courier provider?
We use DHL, FED-EX and UPS for delivery.

 

What is Luxeon?
Luxeon is a patented, technological breakthrough in solid state lighting. It's considered the world's brightest LEDs in the smallest form. The brightest Luxeon can produce 120 lumes of light. That's about 200 normal LEDs combine together!

 

Return Policy
If you change your mind about the order, please return it unused within 7 days... Send an email to the Returns Department to get a RMA (Returns Merchandise Authorisation) Number. We shall deduct 20% from the order as administrative & handling fees. Shipping charges are not refundable. The shipping cost of the returns goods shall be borne by the customers. details...

 

What is the different between the Luxeon Star, Luxeon V Star and Luxeon Emitter?
Luxeon Emitter is the "heart" of Luxeon Light, the main building block of Luxeon Products.

Luxeon Star is basically Luxeon Emitter on a hexagonal MCPCB (or Star configuration). Their nominal voltage is 3.65V and 350mA. By default, it's known as Luxeon 1 Watt version.

Luxeon V Star is basically 4 units of Luxeon Emitter in die form on a single chip on a hexagonal MCPCB. They are connected in series and parallel thus having the Voltage of 6.5V and 700mA. By default, they are know as the 5 Watt version (notice the roman V sign denotes 5 Watt). Luxeon V Star is four times brighter than Luxeon Star.

MCPCB or Metal Core Printed Circuit Board is basically a PCB that is made out of metal properties. Aluminium is the most commonly used in the industry. In the case for Luxeon Star, it's made out of Aluminium. The purpose for MCPCB is like a Heatsink on a CPU (Central Processing Unit), to dissipate heat.

 

What do I need to drive a Luxeon? (No, it's not driving a Lexus!)
Luxeon require very high current source at low voltage.

One unit of Luxeon Star (1 Watt version) requires 350mA (0.35A) for maximum brightness, and if you pulsed the output, you can drive supply it with 400mA (0.4A)

There are two basic ways to drive a Luxeon.

1. Continious current

2. Pulsed Current

Pulsed current output is considered a better design compare to Continuous Current Output. The definition for Pulsed Current Output is connecting the Luxeon with a current source at fixed (or variable) frequency (switching it ON and OFF).

Layman terms: Imagine a LED. When connect it to a power source and switch ON the power button, it will light up. When you switch OFF, it will dim out. Try doing this ON and OFF at a faster rate. Let's say 10 times a second. You'll notice your LED is flashing (10 times per second or 10Hz).

If you increase it further, let's say at 50 times per second (50Hz) you can hardly notice the LED is blinking. The reason is our eyes are slow in reacting changing of images above 25 times per second. This concept is used in movie projections and television, where the pictures are projected at 50 times per second.

Referring back to LEDs, by increasing the frequency, we can actually supply the current higher than normal. This current is labelled as Ip in the datasheet.

 

Do we sell the Luxeon driver?
Yes, we do. Please click here for details...

 

Why does the Luxeon get hot when it's operational?
The main technological break through is condensing it into small space. In normal LED, there is a big metal leg (catod). Imagine putting 200 LEDs together into a single die. The designer in Lumiled solves the heat problem by channelling the heat through the Slug (a metal at the bottom of Luxeon). A Heatsink is then connected to the slug. A thermal conductive paste must be use in between the Slug and the heat sink.

 

What's the size of the Heatsink required for Luxeon 1 Watt?
Please refer to Lumiled's datasheet for accurate calculation...details....

A general rule of thumb, 1 Watt of Luxeon require about 1 square inch of Aluminium. This is the absolute minimum, as with any Heatsink, the bigger the better. Solid state device last longer f they are cooler. Their lifetime is inversely proportionate with the Heat. The hotter it gets, the shorter the lifetime.

 

Who's the manufacturer of Luxeon?
Lumiled is the manufacturer of Luxeon. It's basically a joint venture between Philips lighting and Agilent Technologies. Click here for details....

 

How bright is Luxeon compare to normal LED?
This is a rough estimate. Please refer to datasheet for more information.

On average, but it depends on the colour.

1 unit of Luxeon 1W = 20 to 50 units of LEDs

1 unit of Luxeon V or 5W = 80 to 200 units of LEDs

 

How long does Luxeon last?
According to the manufacturer and research data, solid state device or Luxeons or LEDs have operating lifetime of 100,000 hours. That's basically 22 years, if you use it 12 hours per day.

As with most solid state device (solid state by definition is a device which does not have any moving parts and is made from silicon) Luxeon share the same characteristic with ICs (Integrated Chips). They are long lasting and normally will not fail under normal conditions.

Remember your cassette player; most of them would have broken down in a couple of years. Even after your cassette player has broken down, the radio is still working. Radio is known as a solid state device, as they are not working/moving parts for it to break down.

This is true for MP3's player. These are solid state devices that will last a long time too compare to their cousin, the CD's player or Walkman. Please bear in mind, that MP3 will not last as long as radios because they use flash memory to hold their data. There are a maximum number of times before the flash memory will fail.

Why is Luxeon more energy saving compare to incandescent Bulb or Fluorescent Lamp?
Incandescent Bulb or Filament Bulb as its normally known was invented by Thomas Edison. It's not energy efficient.

Let me explain how you define energy efficient.

For example, 100 Watt of energy. You put it into a normal Incandescent Bulb or Filament Bulb. Out of that 100 Watt of energy you put into the bulb, 80% (or 80 Watt) is used to heat up the tungsten filament and 20% (or 20 Watt) is used to produce the light. This means only 20% is used to produce light and 80% wasted as heat. Efficiency is 20%

As for solid state light, LEDs or Luxeon, they are very efficient. For the same scenario of 100 Watt, 90% (or 90 Watt) is converted into light and only 10% is wasted. This means that Luxeon has 90% efficiency.

I would like to point out also, that if the incandescent bulb is used in air-conditioned location, the heat produced by these bulb will increase the air temperature, thus increasing the demand of air-condition, i.e. more money on electricity bills.

Is order online secure?
Actually this is a good question. At this moment, there are almost a million online stores in the World Wide Web or internet. Every second, monies are transferred over the internet. Ebay.com has the world's biggest online store. They basically sell everything there!

Buying online here is as secure as buying or selling on eBay. We use an encrypted technology (with 128 bit encryption) to send your credit card details, (notice the http:// changes to https://) to denote secure transaction. This also can be seen on the bottom left hand side, a small padlock icon

 

What type of card do you accept? Credit card, charge card or debit?
We accept most major credit card, charge card and debit card. Please see below.

 

If you do not find the question to your answer, or still in doubt, please email us here.
