LED FAQ

A Light Emitting Diode (LED) is an electronic device that produces light when an electrical current is passed through it. The wavelength (or color) of light that is emitted is dependent on the materials from which the LED is made. LEDs are available in many colors, including red, blue, amber, green, and near-UV colors, with lumen outputs ranging from 10 lumens to 200 lumens.

The LEDs used predominantly in general illumination applications are "Phosphor Converted Blue" LEDs, which are blue LEDs that have a layer of yellow phosphor placed over the LED. The phosphor absorbs some of the blue light, and emits yellow light. When the unabsorbed blue light mixes with the yellow light it creates what your eye perceives as "white" light.

What is LED?

 

Why Use LEDs?

Here are just some of the basic benefits and advantages of using LEDs for general illumination:

  • LEDs (Light-Emitting Diodes) are approximately 10 times more efficient than incandescent bulbs at turning energy into light.

  • LEDs can emit light of an intended color without the use of color filters that traditional lighting methods may need.

  • The solid package of an LED can be designed to focus its light from the source. Incandescent and fluorescent lights often require an external reflector to collect light and direct it in a usable manner.

  • When used in applications where dimming is required, LEDs do not change their color tint as the current passing through them is lowered, unlike incandescent lamps, which turn yellow.

  • LEDs are ideal for use in applications that are subject to frequent on-off cycling, unlike fluorescent lamps that burn out more quickly when cycled frequently.

  • LEDs produce more lumens per watt than traditional incandescent bulbs.

  • Since LEDs are solid state electronic components, they are difficult to damage with external shock. Fluorescent and incandescent bulbs are easily broken if dropped on the ground or experience extreme shock or vibration.

  • LEDs can be designed to have extremely long life spans of up to 100,000 hours. By contrast, fluorescent tubes typically are rated at about 10,000 hours, and incandescent light bulbs at 1,000-2,000 hours.

  • LEDs mostly fail by dimming over time, rather than the abrupt burn-out of incandescent bulbs.

  • LEDs require no warm-up period and light up to full brightness very quickly compared to other light sources.

  • LEDs are typically very small, allowing for new design concepts and methods for general illumination products.

  • LEDs do not contain mercury or other harmful chemicals or substances, as compact fluorescent and metal halide lamps do.

 

Watts vs. Lumens

A watt is the measure of power consumption, and is the common way incandescent light bulbs are identified -- for example 60-watt, 75-watt and 100-watt. When purchasing a light bulb, however, what you really should look for is lumens, which is the measure of light output. When you purchase a 60-watt incandescent bulb, you are getting about 800 lumens. Due to the way that LEDs produce light, it is possible that an LED bulb or fixture that produces less lumens can appear just as bright if not brighter than the original light source being replaced.

 
 
 

What are the Color Temperature Stability, CRI and Selectivity Policies of the LEDs Used in Our Products?

The factories our suppliers use selectively choose only top quality LED direct manufacturers and trustworthy suppliers for high quality LEDs that meet the desired and/or required design specifications for each product. Only LEDs that consistently and accurately perform according to the specifications for the product are procured for use in the lamps and luminaires. The LEDs are tested for chromaticity (color) and luminous flux (brightness) and then sorted before they are packaged and shipped from their respective factory ready to use per the product application requirement (i.e. on roll for pick and place machine or insertion machine, in bin/box for manual application, blister-pack, etc.).

 

How Long is the Warranty for Our Products?

Our manufacturers are pleased to provide the following limited warranty for its products. All of our products are warranted to be free of defects in materials and workmanship for a period of one (1) year, three (3) years, five (5) years, or ten (10) years, based on the specific product and manufacturer. Warranty is limited to replacement of product upon verification of purchase, valid warranty period and proper handling. See full details on our warranties here.

 

Flicker and Glare

Without flicker and glare LED Lamps can dramatically improve productivity, readability, eyesight and headaches when comparing with conventional light sources including HID and Fluorescent Lamps that generate much flicker.

 

Noise

The solid state nature of LEDs allows lamp designs that inherently do not produce any humming or buzzing, allowing users to remain comfortable and free from the significant distraction that these issues cause.
