Lumen is the measurement of brightness as perceived to the human eye.
Because of incandescent lighting, we are all accustomed to using watts to
measure the brightness of light. Today, we use lumen. Lumen is the most
important variable when choosing which LED Strip, you need to look at.
Make sure you compare lumen output between LED strip lights before determining
which one is best for your project. 

This is Alternating Current. This is the electricity that is used in
most homes and commercial spaces. It is often referred to as line voltage and
number differs from country to country. India line voltage is typically220-240V

This is Direct Current. Most LED strips on the market use low-voltage
DC. A transformer or low-voltage battery is often required to step-down the AC
voltage to a suitable level for the LED strips, which is normally 12V or 24V
DC.

All our strip lights require constant voltage. A constant voltage power
supply is an electrical power source that regulates voltage to a constant
level. In the case of few specific LED strip lights, a constant 12V or 24V,
depending on the LED strip being used, would be required.

Color Rendering Index (CRI) is the measurement of how colors look under
a light source when compared with sunlight. Having information on the CRI of a
LED strip light is important, because you want to make sure that the colors are
being accurately represented by the light source. CRI is measured on a scale
from 0-100. A CRI of 80+ is the industry-standard for most applications while a
CRI of 90+ tends to be necessary for situations that need color accuracy. Our
COB High CRI lighting is used for photography lighting, retail lighting,
bathroom or salon lighting, and residential lighting.

LED pitch is the distance between the individual chips on a strip
(FPCB). It is crucial to understand the importance that pitch plays in your
project. The shorter the pitch, the more uniform the light tends to be and the
less spotting you have.

LED chips are all not all equal. The four digits represent the size of
the chips in millimetres. For example, the 3528 chip is 3.5 mm X 2.8mm. Some
chips are brighter than other and some have special uses and restrictions.

The color of light can be quantified by referring to its color
temperature. White light is measured in Kelvins (K). Most white lights fall in
a spectrum between 1800K and 6500K. When getting close to 3000K, the light is
noticeably warmer. On the other end of the spectrum, the lights have a blue
tint and cooler tone when nearing 6500K.

Choosing the correct color temperature lights for your project is very
important, and as important as the brightness you choose. Consider the look and
feel you want your project to have. What other color lights will be present?
What material and color are the materials you wish to light?

This is 1/1000 or 0.001 of 1 ampere. When using LED strips, it is common
that the current draw for the LEDs will be less than one amp. In this case
milliamps are used to indicate the amp draw. An example of this would be that a
draw of ½ amp would be equal to 500mAh.

A watt is equivalent to one joule per second, corresponding to the power
in an electric circuit in which the potential difference is one volt and the
current one ampere. A watt is equal to the voltage multiplied by the amperage.
This is how your electric company keeps track of how much energy you consume.

Simply put, binning is the process of grouping LEDs during production so
that they matched with LEDs of the same color sector. For example, all 2700K
chips are ‘binned’ together and are separated from chips that have a
higher/lower color temperature.

This is one of
the most important factors with LED technology butalso the most overlooked. We
use the same color BIN for each manufacturing run of LEDs
within their color temperatures. This means that when you order a
3,000K warm white LED strip light today and order the same product next year,
there will be no perceivable differences to the human eye. We bin 3 MacAdams
and have strict in-house batch testing to ensure that your lighting is perfect.

This is calculated by measuring the
lumen output and then dividing that number by watts. For example, a strip that
has a lumen output of 300lm/ft and a wattage draw of 3w/ft has an efficiency of
100lm/W.

This is an alternative to the unsaturated CRI measurement colors. There are 15 highly saturated colors that are used to compare chromatic discrimination, human preference, and color rendering.

This is a rating system that defines the ability of a product to be able to work in different environments. IP is an acronym "Ingress Protection". It is a measurement of the protection an item will have against solid objects (dust, sand, dirt, etc.) and liquids.

An IP rating is comprised of 2 numbers. The first number refers to the protection against solid objects (dust, etc) and the second number refers to protection against liquids. 

The differences between commonly sold IP65, IP67, & IP68 strips are slight, but very important. Using the above chart as a guide, we can see that all strips are protected at the highest level from solids and dust. The variations come with the protection against liquids.

• IP65 = Water resistant. “Protected against water jets from any angle” *Do NOT submerge IP65 LED lights, these are not waterproof.
• IP67 = Water resistant plus. “Protected against the events of temporary submersion (10 minutes)” Do NOT submerge IP67 LED lights for extended periods, these are not waterproof.
• IP68 = Waterproof “Protected against the events of permanent submersion up to 3 meters”
