A. Close connection with manufacturers of LED chip and LED packaging, Unibond has two divisions, one is acting as agent of Taiwan LED chip manufacturers, another is LED lighting maker. We has close connection with a lot of bigger manufacturers in LED industry, both Taiwan LED-chip maker and LED packaging factories in China mainland. So that we are probably a little earlier than competitors to acquire industry news, trends and other industrial information.

B. More powerful in sourcing LED chips and LEDs, thanks to point a, we purchase LEDs more cost-effective and more efficient.

C. Professional attitude, from purchasing LEDs and other material to delivering LED lights, we do a lot of QC and professional tests, such as LM-79, LM-80, and obey LED Lighting Facts requirement . Fixing the problem in factory is our principle.

 That the incandescent bulb is on its way out is no secret. Edison’s legacy has illuminated our world for more than a century now.  But the light bulb is akin to a dinosaur today. It has had a long innings but leaner competitors are here and like the dinosaurs the light bulb must yield. It is a matter of debate as to which of the two heir apparent technologies shall inherit the light fixture. Technologically speaking, LED''''''''s is certain to trounce the fluorescent lamps.
Below is a list of factors that demonstrate the superiority of the LED lighting over CFLs.

A)    LEDs use less power
A 6 watt LED produces as much light as a 50 watt traditional bulb. The figure for CFL is close to 13 watts. An LED thus uses half the amount of electricity compared to a CFL. In the era of carbon emission controls, tight budgets, and awareness about the need to preserve the earth for our children – Solid State LED based lights easily score over CFLs. An LED bulb uses 50% of the energy of a CFL and that means lower utility bills and fewer carbon emissions.

B)    Unlike LEDs, a CFL may require the replacement of the expensive light fixtures
CFLs are less suited to be used as retrofits in existing sockets. Given that a CFL must accommodate an electronic powering device and long tubes, they are often too large for existing light fixtures. One must either do without the beautiful light covers or else change the light fixture itself. Any cost advantage that the CFL enjoys over LED is wiped out the moment one factors in the need to replace the light sockets and fixtures.

C)    LED lasts up to 10 times longer than a CFL
This means lesser recurring costs to be incurred to purchase new lights, fewer trips to the market, fewer anxious moments, and almost nonexistent headache of replacing burnt out lights. This also means less solid waste to be disposed and makes this light ideal for hard to reach locations.    

D)    LED lighting generates less heat than a CFL
This reduces the risk of burn injuries and places a smaller heat load on the air conditioner.

E)    LEDs do not contain Mercury or other toxic heavy metals
CFL lights contain a small amount of mercury and must be disposed off in accordance with the regulations for hazardous substances. LEDs, on the other hand, contain no heavy metal and can be safely disposed off with common waste.
The mercury poisoning due to CFL lights is often underplayed. It is true that the amount of mercury in a single CFL is only 5 mg and much more mercury is emitted by burning coal to provide electricity to operate an incandescent bulb. However, if every light fixture were to be converted to CFL light an average household would dispose close to 10 CFL lights every year. Back of the envelope calculations show that the 115 million households in the US will together release close to 5 tons of mercury in the environment every year – contaminating rivers, landfills and ground water. LED bulbs comply with ROHS regulations meaning that they do not have any of the toxic heavy metals like lead, mercury or cadmium.

F)    LED does not emit UV radiation
CFLs produce UV light that can damage cells, reduce folate levels in the body and may even lead to skin cancers. LED lamps on the other hand do not produce any UV light. Another disadvantage of CFLs is that the emitted UV light can damage precious art objects and paintings.

G)    LEDs are not sensitive to on- off cycling
CFLs are not suited to uses that involve a high rate of on- off cycling like outdoor lights, motion sensors etc. A high rate of on-off cycling drastically shortens the life span of a CFL. An LED on the other hand is unaffected by on – off cycling. This is the reason LED devices are preferred for traffic lights.

H)    LED lamps produce unidirectional light
Comparing LED with CFLs is like comparing oranges and apples. For starters there is no relation between the wattage and light emitted by a CFL and an LED. Moreover, LED’s produce unidirectional light – this means that it is easier to control the light. You can choose to focus it for spot lighting or use a lens for diffused lighting applications. On the other hand, light emitted by a CFL, like that from incandescent bulbs, is multidirectional and difficult to control. A lens can easily collect all the light emitted by an LED and disperse it. A CFL on the other hand relies on a reflector to achieve to spread the light and a portion of the light is always wasted. An LED lamp can thus be used to replace a CFL or incandescent lamp with a higher light output.
