Are E26 and E27 light bulb bases interchangeable?

Yes. The E26 is the standard 120 Volt American base. The E27 is the European variant and is rated at 220 Volts. E26 is 26 mm and the E27 is 27 mm diameter. However, an E26 bulb can fit in E27 base and an E27 bulb can fit in E26 base without problem. The sockets / bulbs are interchangeable except for the voltage rating. Therefore, LED E26 bulbs that are universal line-voltage can be used in both E26 and E27 sockets.

What color temperature is well suited for diamonds and jewelry in general?

The best color temperature that is well suited for diamonds would have to be in the range of 6000-6500K or Kelvin color temperature. 6000K is your neutral white daylight color, anything under will start to turn to the yellow category and anything above will turn to the blue category. A bluer cast over diamonds will sparkle them fantastically, but they would give a lot more of an unnatural tone to the jewelry. Therefore getting the best possible neutral daylight look will not only sparkle your jewelry but bring out the scintillation and clearly define the Cut, Clarity and Color of your diamonds as well as all your other jewelry whether it be fine jewelry, fashion jewelry or costume jewelry.

How does ambient temperature affect LED efficiency? What is junction temperature?

LED fixtures must be designed with junction temperature thermal management as a key component and use the correct LEDs. These products will then be robust enough to operate in most ambient temperature applications. Unlike fluorescent sources, cold temperatures do not impact the performance of LEDs.

Junction temperature is the temperature at the point where an individual diode connects to its base. Maintaining a low junction temperature increases output and slows LED lumen depreciation. Junction temperature is a key metric for evaluating an LED product’s quality and ability to deliver long life.
The three things affecting junction temperature are: drive current, thermal path, and ambient temperature. In general, the higher the drive current, the greater the heat generated at the die. Heat must be moved away from the die in order to maintain expected light output, life, and color. The amount of heat that can be removed depends upon the ambient temperature and the design of the thermal path from the die to the surroundings.

How to avoid voltage drop in a circuit?

Design the circuit with the shortest path possible between the electrical source and the end devices. The voltage drop in a circuit is increased as the length of the conductor is increased. Designing a circuit with the shortest possible cable run reduces voltage drop and saves significant investment required for conductor material.

Increase the conductor thickness, lower the gauge, to reduce resistance. Resistance is a naturally occurring process in conductor material. Resistance reduces voltage and converts the lost energy to heat. Increasing the thickness of the wire lowers resistance, and as a corollary, voltage drop,in a circuit.

Remove any unnecessary connectors between the electrical source and the end point of the conductor. For example, it is preferable to run one long length of conductor material as opposed to two smaller lengths that are spliced together. Connectors reduce voltage and provide points of weakness in the circuit.

Can I use a LED bulb in a Line Voltage Housing and Trim?

Yes, LED bulbs can be used in Line Voltage Housings and Trims. These types of bulbs are readily available in Par, R and A shaped bulbs. It’s important to note, that the shape of the bulb should be as close to the bulb specified by the manufacture as possible. For example, if the housing and trim are recommending a Par/R shaped bulb, the LED bulb should be in a Par/R shape. However due to the length and width of some bulbs, the light pattern given off by the bulb and the overall look, may not be what was originally intended.

What is a LED puck light?

LED puck lights are small lights that use light emitting diodes (LEDs) to create lighting for an area that is typically out of the way or otherwise difficult to light. These lights are generally small and self-contained, running on batteries or through solar charging for nighttime use. Some of these lights are intended for fairly permanent use and can be connected to a surface through a mounting bracket, though other lights are designed to stick in an area and be removed later. LED puck lights can be activated in a number of different ways, and can be simple white lights or provide colored illumination.

Sometimes called “under cabinet lights,” LED puck lights can be utilized both indoors and outdoors for many different purposes and in different spaces. These lights are typically fairly small and round, similar in general size and shape to a puck used in ice hockey, from which they have received their common name. They are often manufactured in a disc shape and are circular, usually with either two flat sides for mounting and illumination, or a single flat side for mounting and a dome shape that provides illumination. Most LED puck lights have several LEDs within them, providing sufficient illumination for a small area indoors or outside.

What is wire gauge?

Wire gauge is a measurement of how large a wire is, either in diameter or cross sectional area. This determines the amount of electric current a wire can safely carry, as well as its electrical resistance and weight per unit of length. Wire gauge is applicable to both electrical and non-electrical wires, being important to electrical wiring and to structural cable.

LED lights and Optic Fiber

LED lights and Optic Fiber

Optic Fiber Lighting in essence is only about carrying light, from one point to another by means of a lens, more or less flexible and long. There optic fibers come in different forms in lighting. Because of the features of the fiber, like safe as no electricity with it, wet/water resistant, flexible, it is used for various lighting applications.

What Kind of Optic Fiber should I use for my pool lighting?

Side-glow solid optic fiber is used for pool lighting. This optic fiber work with the lighting machine, can give a lighting effect like the LED flexible strips from appearance. And it is water resistant and the fiber itself carries no electricity, which is quite safe.

I saw some fabulous lighting like starry sky in some places; I want to have that in my home. What kind of lighting is that?

To create an outdoor starry sky, the end-glow optic fibers can be used. It comes with fiber be wrapped in black jacket with light glow at the end of the fiber only.  图片4 图片5

 

I live outside of the United States and would like to use your LED lighting. Are your products adaptable to different line voltages?

Many of our LED lighting and systems are 100-240VAC (universal voltage), so we can meet the entire worlds lighting needs during this LED revolution. We can also meet your custom needs of other voltage levels if required including up to 277V. By the way, some of our products are 12V DC/AC, such as the LED strip light, G4 LED bulb, etc. For these 12V products, you will need a transformer, like 120/240V to 12V DC transformers.
