Numbers and LEDs: What does 2835, 3528 and 5050 mean?

Numbers and LEDs: What does 2835, 3528 and 5050 mean?

All these numbers! What's going on?


Have you ever been looking for LED light strips and ran across the numbers 2835, 3825 or 5050? Well, these numbers are less mysterious than you might think.

(Shop our LED light strips and light strip kits here)

First off, you might have seen the letters "SMD" preceding these enigmatic numbers. The abbreviation SMD  refers to a 'Surface Mounted Diode'.  That means this is an LED Chip  mounted directly to a light strip, without using wires. This surface mounting technology is indeed what makes LED Light Strips possible. The numbers after the SMD simply refer to the physical size of the LED Chip. Take SMD 3528 for example, they are 3.5mm wide and 2.8mm long.

Luma5, Luma10 & Luma20 Series


Hitlights.com carries 3 main types of LEDs that each fall into their own product lines. Strips that have SMD 3528 LEDs are called Luma5; SMD 5050 are called Luma10; and SMD 2835 are called Luma20.

SMD 3528 (LUMA5)


SMD 3528 Chips (Which are utilized in our Luma5 strips) are perhaps the most common of all LED light strip chips. They are the least bright and least power intesive of the three chips we use at HitLights, and are most commonly used for accent lighting, such as above kitchen cabinets and around the crown moulding below the ceiling. Our Luma5 strips typically contain 18 LEDs per foot and come on a 5 Meter (16.4 Foot) Roll.

SMD 5050 (LUMA10)


SMD 5050 Chips (Which are utilized in our Luma10 strips) are just barely behind the 3528 chips in popularity. These chips are 5.0mm x 5.omm. Each 5050 chip is 3 times as bright as a 3528 chip, so they start at 9 LEDs per foot, meaning that the Luma10 strips are 1.5 times as bright as the Luma5s. Because they're brighter, Luma10 strips are typically used for what we call 'task lighting', and is commonly used underneath kitchen cabinets, for example, where that light will help you see what you're working on. Our Luma10 5050 strips are also available in color changing styles, meaning that you can select any color you want with a remote or controller. The Luma10 Strips also come on a 5 Meter (16.4 Foot) Roll.

SMD 2835 Used in Luma20


SMD 2835 Chips (Which are utilized in our Luma20 strips) look very much like 3528 chips, but they are 4.6 times brighter. They're smaller than the 5050 chips (2.8mm x 3.5mm), but at 18 LEDs per foot they are 4.6 times brighter than the Luma5 Strips and 3 times brighter than Luma10. The Luma20 strips are BRIGHT! They make the ultimate in task lighting and even work lighting, as their Lumen output per foot rivals that of most household fluorescent tubes. The Luma20 strips are available on a 3 Meter (10 Foot) Roll.
