hao does led bulbs'colour change?

Reply: Current can change the color, light-emitting diodes easily modified by chemical methods, adjusting the material band structure and band gap, to achieve multi-color red green blue orange luminescence. Such as when under the small current it is the red LED, with an increase in current, you can turn into orange, yellow, and finally to green

Dose LED bulb emit heat?

Reply: LED bulbs is that they do not give off very much heat which can be regarded as very good considering other incandescent bulbs can give off most of its power as heat which reduces your bulbs lifespan. All of a LED bulbs power goes into producing light so the efficient of LED bulb will be as hight as 85LM per watt.

What temperatures does Led light bulb work properly?

Reply: If temperature below 14¡ã F or above 122 F may cause a LED bulb to flicker, dim, change color, or cease to function. Once the LED bulb is returned to an operational environment it should began to work properly. They should not be used in a enclosed fixture with a cover over it. This will raise the temperature.

What is PAR?

Reply: PAR is a kind of bulb measurement standard. Under this system of lamp identification the first number listed denotes the maximum diameter of the lamp expressed as a number of 1/8's of an inch. For example, some common sizes are:

PAR-38 (4.75")
PAR-30 (3.75")
PAR-20 (2.5")

Our bulbs currently provide ¡°medium¡± or ¡°Edison¡± base; which means they will fit into most base in home.

Dose LED light bulbs can work on a dimmer switch?

Reply: No, we do not advise using our LED light bulbs work on a dimmer switch, this type of switch may cause damage to the bulb. Many dimmer switches do not have the true "off" position and will continue to illuminate an LED bulb even turned all the way down because LED bulbs use so little power.

Are led bulbs safe ?

Reply: Unlike traditional incandescent Christmas lights, LED lights do not get hot ¨C a big plus if you will be using them on a real tree; but really a big plus for anyone and any use.

how about the future of led bulbs

Reply: Perhaps the ultimate ¡°alternative to the alternative,¡± the LED (light-emitting diode) light bulb may well dethrone the compact fluorescent light (CFL) as king of the green lighting choices. But it has a way to go yet in terms of both affordability and brightness.

are led bulb better than CFLs

Reply: LED bulbs are lit solely by the movement of electrons. Unlike incandescents, they have no filament that will burn out; and unlike CFLs, they contain no mercury or other toxic substances. Proponents say LEDs can last some 60 times longer than incandescents and 10 times longer than CFLs. And unlike incandescents, which generate a lot of waste heat, LEDs don¡¯t get especially hot and use a much higher percentage of electricity for directly generating light.

The GU10 LED bulbs have previous future.

Reply: GU10 LED bulbs are one of the most widely used for interior lighting in the word and is compatible with commercial voltages ranging from 110V to 220V(sunlp high power version). Currently, the market for GU10 LED is over 300 million bulbs per year and is worth approximately 1.2 billion dollars globally. GU10 LED is the predominant lamp-type where befor halogen bulbs are used for interior lighting sources. Recently, GU10-base lamp products using LED¡¯s, which take advantage of long life and efficiency are in the limelight.

What does color temperature mean?

Reply: Counterintuitively, higher color temperatures (5000 K or more) are "cool" (green¨Cblue) colors, and lower color temperatures (2700¨C3000 K) "warm" (yellow¨Cred) colors.
For example:
Temperature Source
1700 K Match flame
1850 K Candle flame
2700¨C3300 K Incandescent light bulb
3350 K Studio "CP" light
3400 K Studio lamps, photofloods, etc.
4100 K Moonlight, xenon arc lamp
5000 K Horizon daylight
5500¨C6000 K Typical daylight, electronic flash
6500 K Daylight, overcast
9300 K CRT screen
If choose LED bulbs:
Approx. 2700K = Warm White (looks just like incandescent)
Approx. 5000K = Cool White (white/blue, often higher CRI)

How choosing an LED bulbs?

Reply: Many different models and styles of LED bulbs are available in the market. When choosing a LED bulb, keep in mind the following:
1. Estimate desired wattage - read the specs to choose desired illumination level. Generally, a 3W LED is equivalent in output to a 30 W incandescent.
2. Choose between warm and cool light - Now LED bulbs are available in 'cool' white, which is ideal for task lighting, and 'warm' white commonly used for accent or small area lighting.
3. Standard base or pin base ¨C LED bulbs are available in several types of 'pin' sockets or the standard "screw' (Edison) bases E26 E27 for recessed or track lighting GU10 GU5.3.

What is Benefits of LED bulbs?

Reply: Long-lasting - LED bulbs last up to 10 times as long as compact fluorescents, and far longer than ordinary incandescents.
Cool - LED bulbs do not cause heat build-up. The LEDs produce 3.4 btu's/hour, compared to 85 for incandescent bulbs.
Mercury-free ¨C There are no mercury is used in the LED bulbs.
More efficient - LED bulbs use around 2-10 watts of electricity (1/3rd to 1/30th of CFL or Incandescent). For example LED flashlight bulbs will extend battery life 10 to 15 times longer than with incandescent bulbs. Also, because LED bulbs last for years, energy is saved in maintenance and saving costs. For example, many cities in the US are replacing their incandescent traffic lights with LED arrays because the electricity costs can be reduced by 80% or more.

What color does the led bulb have ?

Reply: There many color to choose of LED bulbs
Red ¨C red LED bulbs is the traditional color for maintaining night vision.
Green ¨C green LED bulbs r is great for retaining night vision, and it doesn¡¯t erase the red markings on maps and charts.
Blue - Blue LED bulbs many people like the blue because it is very easy on the eyes. Blue LED bulbs appears to be a good reading light for elderly eyes. Elderly folks report that they can read under the blue LED bulbs for hours without eyestrain, compared to severe eyestrain in less than 30 minutes with incandescent lighting.
White - the most popular of the LED bulbs colors. It produces a soft white light, without harsh reflection, glare or shadows.
Amber ¨CWe also call warm white LED amber bulbs do not attract flying insects, as do ordinary white bulbs. Amber LEDs are used outdoors in areas such as patios and decks where insects flying around lights are a nuisance.

How about the LED bulb life time?

Reply: Simply, LED bulbs have longer life time over ordinary incandescent bulbs. LED bulbs has been tested and proved that the operational life of white LED bulbs is approximately 100,000 hours. This means that with continuous use, you can actually benefit from your LED Bulbs for more than a decade. On the contrary, the incandescent bulbs, which primarily uses filaments, has an average of 5,000 hours-roughly just about five per cent as compared to the LED's. Basically, filaments used in incandescent bulbs easily heat up and burn out that causes shorter life time.
