Part 1: Technical Questions
Q: Where do you recommend using led rope light?
A: We recommend led rope light to be used in all commercial applications. This way, you will not need to replace the rope light for years reducing maintenance costs! We also suggest using led rope light in confined spaces and in places where rope light might be laying on a surface.
Q: If led rope light uses less watts, will it be dimmer than the traditional one?
A: No, watts are a measurement of power. Lumens are a measurement of light. Led rope lights have more lumens than traditional rope light does. Actually led rope light is brighter.
Q: If I am replacing an existing rope light, what rope light should I use?
A: Use led rope light, if there is obvious heat damage of the existing one, then you will need led rope light, so, it will not happen in the future.
Q: Can I cut rope light?
A: Yes, our rope lights can be only cut at the specified points with cutting marks. For 240V AC rope lights, minimum cut is every 2 meters (6.6 feet); for 120V AC, minimum cut is every 1 meter (3.3 feet).
Q: What are the benefits of LED neon?
A: Neon gets attention! Not only is it highly nostalgic, but it has an eye appeal and unique spectral properties that incandescent lamps cannot offer. It comes in many colors and is flexible in design. Neon is affordable and power efficient, costing just pennies a day to operate. And it is really energy saving. Why not put the brightness and attention grabbing power of neon to work for you?
Q: How long does LED neon last?
A: LED Neon can last decades. In practical terms the expected life span is up to 50,000 hours for a neon sign powered on 24 hours per day.
Q: Can LED neon be cut?
A: Yes, the same as rope lights, 2meters for 240V, 1 meter for 120V.
Q: Can your LED wall washer be used for outdoor?
A: Yes, It is IP65 rated, applicable for outdoor standard.
Q: How much more do I have to pay to use energy-efficient lighting?
A: The goal is that you actually pay less energy-efficient lighting, including all the cost factors: the bulbs, the cost of replacing the bulbs, and the power.
Q: But in my state, electricity is really cheap. We don't need energy-efficient lighting here, right?
A: Wrong. Check your bill carefully. Add up all the surcharges and look at the marginal cost of powerthe last KW-hour you bought. Frequently that marginal cost is higher than the average cost youre paying. If you cut your electricity consumption, youll probably save more than you think.
Plus, your electricity rates are going to rise, just like the cost of a gallon of gasoline. Finally, wouldnt you like to help reduce global warming? Choosing energy-efficient lighting is the right thing to do.
Q: Does installation need to be finished under power off?
A: Yes, please keep power off until you finish all the installation, or the fuse of driver will be burned.
Q: What is the color of led ropes and neon series?
A: Red, Yellow, Blue, Green white.
Q: How much is the led ropes and neon series?
A: Pricing should be comparable to a compact fluorescent down lights, trim and lamp.
Q: What's the operation voltage?
A: Its operation voltage is 110/120v ac; 200-240 v ac for Europe, we didnt recommend 12V DC or 24V DC due to quality issue.
Q: If one LED fails, will other LEDs fail?
A: No, if one LED fails, the remaining LEDs will still work.
Q: Is there any accessories?
A: Yes, please check accessories page.
Q: Whats the maximum length of one strip in series?
A: Yes. The maximum length is 100 meters in series for 220-240 v input, 50 meters for 110-120 v ac input.
Q: Whats the led type of neon and rope lights?
A: it adopts 2-pins LEDs, the model is 5 mm diameter.
Q: What brand of your LEDs of the neon and rope lights?
A: We adopt Epstar LEDs.

50000 hours lit for 12 hours per day will last for over 11 years.
50000 hours lit for 8hours per day will last for over 17 years.
50000 hours lit for4 hours per day will last for over 34 years.
Q:What if I have a question thats not covered in this list of questions?
A: Email us.
Q: why should I replace the conventional lights with LED?
A: The main targets are both white, including warm white light sources and color light sources. The latest LED technology opens up wide areas for new applications, new technical possibilities and reduced costs. The main advantages of the state of the art LED light sources are:
(1) The life time of an LED reaches or frequently exceeds the life time of the application and there are often no special changes necessary. If one defines the failure criteria as end of life when the light intensity of an LED has reached 50 % of the initial light intensity, depending on the model, one can calculate numerical life times above 100,000 hours for LED Chips based on GaAs.
(2) In the case of colored light the power consumption is below the power consumption of white light sources with filter glass (see table below). White LEDs can now reach the level of fluorescent triphosphore tubes and standard white LEDs show a better efficiency than incandescent or halogen lamps.
(3) The radiant intensity of an LED is controllable in the whole range without any change in the light properties (e.g. dimming of incandescent lamps leads to a shift in color temperature) and any time loss (switching time of LEDs for general lightening < 1 s). The PWM (pulse width modulation) is the recommended method for the dimming of LEDs. Dimming by reduced DC current may lead to inhomogeneous appearance of LED arrays.
(4) Compared to the high efficient light sources of fluorescent tubes, compact lamps and metal halide high-pressure lamps the switching time of LEDs is very short. This plays an important role especially for applications like head lamps and brake lights in automotive and traffic applications.
(5) LEDs provide excellent stability for mechanical and thermal stress. The reliability of an LED is described by the different failure mechanisms, the spontaneous total failure of the LED and the reduced light intensity of the LED. To calculate the reliability of an LED array one should use the data for spontaneous failure. They should be in the range of 10 ppm/h within the first hour of operation including solder processes and below 0, 1 ppm after the first hours of usage.
QWhat is IP Rating's?
A: The Ingress protection system is an international standard and allows you to easily see how resistant a product is to different environmental elements.
Q: What is lumen?
A: Lumen is amount of light emitted from light source.
According to Wikipedia, "If a light source emits one candela of luminous intensity into a solid angle of one steradian, the total luminous flux emitted into that solid angle is one lumen. Alternatively, an isotropic one-candela light source emits a total luminous flux of exactly 4 lumens. The lumen can be thought of casually as a measure of the total amount of visible light emitted." For example, a standard 100 Watt incandescent bulb emits about 1500 lumen.
Q: What is Lux?
A: Lux is lumen per square meter.
According to Wikipedia, "The difference between the lux and the lumen is that the lux takes into account the area over which the luminous flux is spread. 1000 lumens, concentrated into an area of one square meter, lights up that square meter with an illuminance of 1000 lux. The same 1000 lumens, spread out over ten square meters, produce a dimmer illuminance of only 100 lux."
