A Quick Tutorial about LED Strip Lights

By Echo   Jun 03,2020

What is led strip light?

An led strip light is a circuit board with LEDs populated. It can be flexible or rigid, waterproof or non-waterproof, linear or modular, and is available in a variety of colors. It is generally used for indirect lighting applications such as cove, accents, and creative specialty applications as well.

Analyzing its structure can help you quickly build up a clear picture.

LEDs. The LEDs of a strip light is the most important part that defines a good performance strip or not, and it takes the most part of the cost. There’s many packages available in the market, at  LEDWise, the most popular options are 2835, 3528, 1616, 2110, 5050 and 5050RGB(W). The density is often seen 30 or 35 LEDs per meter, 60LEDs/m, 84LEDs/m, 120LEDs/m and 240LEDs/m. The higher, the evener of the lighting.

Circuit Board or PCB. The PCB can be flexible or rigid, the flex version always comes with an adhesive back. Thickness of a PCB is often 2oz, 3oz or 4oz selectively and width is designed 8mm, 10mm or 12mm. The thicker, the better heat dissipation effect. You can choose it to be white or brown, straight or zigzag.

Power supply & controller & dimmer. Power supply is a must-have unit to power the strip lights. Basically it’s either low voltage (DC) or high voltage (AC). Controller or dimmer is optional depending on what strip light it is. For example, a dimmable strip should combine a dimmer.

What need to be put in mind while buying a led strip light?

You don’t want your strip light fail to generate enough brightness in your kitchen or anywhere you want it to light up, so lumen/watt is a factor you can’t miss. Here’s a chart that helps you to understand how many lumens per watt you may need in different circumstances.

CCT and CRI are two factors that most buyers value a strip light. CCT varies from 2200K to 6000K at LEDwise, and CRI varies from 90 to 95+.

Example Application

Lumen required / foot of LED strip

Accent Lighting and Mood Lighting


Under Cabinet Lighting


Task Lighting with Low Distance from Light Source


Task Lighting with Higher Distance from Light Source


Indirect Lighting in a Bedroom / Hotel / Vehicle / Lobby


Industrial Lighting / Signage / Tube Replacements


If you care about how much a strip costs you every month, you need to look at wattage consumed per strip of LEDs. Wattage tells us how much power we are consuming while these lights are on, and in turn how much we’ll have to pay at the end of each month.
