What is the 2835 LED

PROBLEM: You keep seeing “2835” in specs but don’t know what it means

AGITATION: Confusion between 2835, 5050, and 3528 leads to wrong orders and poor product performance

SOLUTION: This blog breaks it all down — in simple terms that help you buy smarter and save money

Opening Fragment:Not knowing what a 2835 LED really is? You could be wasting money. This guide helps you source smarter, faster, and cheaper.

Transition Paragraph:When sourcing LED chips for your product line, model numbers and codes can be overwhelming. You’ve probably seen terms like 2835, 5050, or 3528 — but which one is best for your needs?

Let’s start with the 2835. The name comes from its physical dimensions: 2.8mm by 3.5mm. It’s a surface-mounted (SMD) LED that delivers high brightness, excellent thermal performance, and compact size — perfect for modern lighting solutions.

Unlike larger RGB LEDs like 5050, the 2835 is designed for white light or warm light output. It’s used extensively in home appliances, LED tubes, medical devices, and backlit panels. For buyers, it represents an ideal mix of low power consumption and high brightness.

In this article, we’ll answer your biggest questions:

What exactly is a 2835 LED?

How does it compare to 5050 LEDs?

What’s the average lifespan of a 2835 LED?

How many lumens per watt can you expect?

Let’s break it down and help you make confident, data-backed purchasing decisions.

What Is a 2835 LED? Small in Size, Big in Output

Problem: Misunderstanding size codes can lead to incorrect sourcing

Agitation: Wrong power specs, poor fit, or mismatched performance

Solution: Understand exactly what "2835" stands for and how it’s used

Lead Paragraph :"2835" isn’t a model number — it’s a size reference. Knowing this helps you avoid confusion and ensures the LED matches your product specs.

Snippet :The 2835 LED is a 2.8mm x 3.5mm surface-mounted chip used mainly for single-color (white) lighting. It’s a favorite for applications like under-cabinet lighting, appliance lighting, backlit displays, and LED panel lights.

Why is it popular?

It’s thinner and flatter than older models like 3528

It offers higher lumen output per watt

It performs well in high-density, low-profile fixtures

It's typically 15–30% cheaper than 5050 LEDs

Common use cases:

LED tube lights

Home appliances (refrigerators, range hoods)

Commercial and office lighting

Beauty and therapy lamps

Its small size doesn’t mean lower performance — quite the opposite. The chip design offers good heat dissipation, long lifespan, and stable light output. For wholesale buyers, this means lower returns and better customer satisfaction.

2835 vs 5050 LED: Which Should You Choose?

Problem: Many buyers think “bigger size = better performance” — not always true

Agitation: Choosing based on size alone can increase costs and reduce efficiency

Solution: Use side-by-side comparisons to choose the right LED for your job

Lead Paragraph:Size isn't everything. While 5050 LEDs are bigger, the 2835 often wins in efficiency, price, and application fit.

Snippet:

Bottom line:

Use 2835 for efficient white light and compact applications

Use 5050 for multi-color RGB effects

Choosing the wrong chip can increase BOM cost or reduce efficiency. Understand your use case before ordering.

What’s the Lifespan of a 2835 LED?

Problem: Lifespan claims range wildly — which ones are true?

Agitation: Poor-quality chips mean higher warranty costs and angry clients

Solution: Trust LM-80 certified LEDs and ask for proper aging test data

Lead Paragraph:Lifespan depends on manufacturing quality, not just the LED type. 2835 LEDs can last over 50,000 hours — if they’re built right.

Snippet:The lifespan of a 2835 LED is influenced by:

Heat dissipation quality

PCB design

Drive current and voltage

Humidity resistance

High-quality 2835 LEDs from reputable manufacturers (like XGM) can last 50,000 hours or more, especially when paired with proper drivers and heat sinks.

To ensure you’re getting top-tier chips:

Request LM-80 test reports

Look for RoHS/REACH compliance

Ask suppliers about high-temperature and humidity tests

These certifications and processes are not just for show — they reduce your risk of DOA units and premature failures in the field.

How Many Lumens Per Watt Does a 2835 LED Deliver?

Problem: Many buyers chase cheap prices, ignoring light efficiency

Agitation: Poor efficiency = higher electricity bills or customer complaints

Solution: Look at lumens-per-watt to evaluate real value

Lead Paragraph:Efficiency matters. The 2835 LED offers 100–130 lumens per watt, making it one of the most cost-effective SMD chips on the market.

Snippet:2835 LEDs are designed for high light output and low energy consumption. Their lm/W rating outperforms older models like 3528 and even rivals 5630 in some applications.

Typical ranges:

Standard models: 100–110 lm/W

High-efficiency models: 120–130 lm/W

Premium binning: 135+ lm/W

Why so efficient?

Low thermal resistance

Narrow beam angles for focused lighting

Optimized chip architecture

Benefits for bulk buyers:

Lower wattage = smaller, cheaper drivers

Less heat = longer board and housing life

More brightness = fewer chips needed per fixture

Ask your supplier to show lumen tests and driver pairing recommendations.
