How much brightness do I need?

LED brightness is usually talked about in terms of density and lumens.2.1 LED Density
The density of an LED strip is the total number of LEDs on the strip. LED strip usually indicates the total number of LEDs in 5 meters/16.4 feet and the number of LEDs per meter/3.28 feet. The denser the density, the more evenly the light is distributed on the strip, with each SMD LED light emitting at an angle of 120 degrees.

Available in low density (30-72 LEDs per meter), medium density (72-120 LEDs per meter), and high density (more than 120 LEDs per meter).

Multiple rows of LED strips can withstand higher densities. If you don't want the LED strip to be too wide or the installation environment is narrow, please don't miss the thin LED strip.

If you want to use LED strip as the main lighting source or have a large lighting area, maybe high density LED strip is suitable for you. On the contrary, if you have a small space and do not require high LED brightness, you can choose low density or medium density. It totally depends on yourself. 2.2 LED Lumens

The lumens of LED strip light is closely related to the LED chip type. LED chip name to SMD LED size. Each LED chip type has its approximate lumens, but lumens will vary slightly from strip to strip.

Lumens/Meter = Lumens/LED x Density/Meter
Lumens/5M = Lumens/LED x Density/5M
Lumens/ft = Lumens/LED x Density/ft

SMD5050 and SMD2835 are the most commonly used chips. Among all SMD LED chips, SMD5050 and COB support color-changing LED lights, such as the familiar LED lights. RGB LED strips. Other chips are monochromatic, including white, dimmable white, red, blue, green, pink, purple and yellow.

If you want higher lumens, in addition to looking at the LED chip, you must also pay attention to the density of the LED strip. The denser the density, the higher the lumens. It is worth noting that high density and high lumens require high heat dissipation and high power.
