Q: What factors you need to consider in choosing your LED lights?
A: There are factors to consider in choosing the right LED:
1. The brightness - Lumens
The brightness is measured by the lumens, not the number of watts as the norm of determining the brightness of a light bulb. The number of watts is the measure of power consumption of the bulb, so if a LED uses high wattage and produces low lumens it simply means that it is inefficient.
2. The colour of the light
Normally LED comes in cool white and warm white.
With the same amount of watts, the cool white has a much higher lumens than the warm white.
3. The beam angle
LED comes with 30,40,60 degree beam angle. The wider the angle, the more diffused the light intensity will be and thus cover a wider area, wherelse with the narrower angle, the light is more focus and thus gives the spotlight effect.
4. The diode chip and the board manufacturer
The chip plays a vital role in the quality and the efficiency of the LED light. The higher the lumens/watt factor the more efficient is the LED.
5. The body of the LED light
The pure aluminium fin provides a more efficient heat
sink and cool the diodes more quickly than the magnesium Alloy. Heat sinks are
used to cool electronic components such as high-power semiconductor devices, and optoelectronic devices such as higher-power lasers and light emitting diodes (LEDs). Heat sinks are heat exchangers such as those used in refrigeration and air conditioning systems, or the radiator in an automobile. However the aluminium heat sink costs more than the other materials.
Q: I want to replace my existing halogen with LED bulb, do I need a different transformer?
A: The power range of ordinary electronic transformers usually are about 20-60W, it's not only too large but also unstable for LED bulbs. The small power that the LED bulb draws is not enough sometime to trigger the transformer and hence it may cause the LED lights to flicker not having enough electric current to sustain.
Changing transformers could be a challenge on its own, the tedious electrical works and the price of the LED transformer itself which is very high and not readily available.
The optimum solution that we provide would be the use of our special designed converter which converts the output AC current from the traditional transformer into a stable DC current that is appropriate for LED.
The converter works on the 12V side which is safe and convenient where you do not have to access the transformer which can be a hassle especially if they are out of reach somewhere in the roof.

Q: What are the specifications that I need to consider in purchasing LED lights ?
A: There are different categories according to different light fittings such as:
A: There are different categories according to different light fittings such as:
- DOWNLIGHT SET
In choosing the right downlight, we need to consider :
- the cutout hole diameter, standard is 90mm
- the height to make sure it fits into the roof cavity
- the beam angle. It comes in various degree such 30, 45, 60, 120 degree
- dimmable or non-dimmable
- SHOP LIGHTERS
In choosing the shop lighter, we should consider:
- the cutout hole size to minimise alterations
- the brightness, make sure it's bright enough for the display
- the Colour Rendering Index, the higher the better colour expression of the object displayed.
- the cutout diameter for round shop lighters come in 150mm and 205 mm.
- SPOTLIGHT
The spotlight comes in 2 lamp bases:
|
- BULB
- G4 bulb
|
- G9 Bulb
