The trend of using low-efficiency LED - two 2835 LEDs versus one 5050 LED as an example

When comparing two 2835 LEDs against a single 5050 LED, it’s helpful to understand the differences between these LED packages and how each configuration affects your lighting needs.

LED Package Differences

• 2835 LED: This type of LED is typically smaller, measuring 2.8 x 3.5 mm. They are efficient and capable of providing good brightness with lower power consumption.
• 5050 LED: The 5050 LED is larger, measuring 5.0 x 5.0 mm. It can have multiple diodes within one package, which enables it to emit higher light levels from a single unit.

Factors to Consider

1. Brightness and Luminous Efficacy:

• 2835 LEDs: Generally, 2835 LEDs can produce around 20-60 lumens per diode depending on the power and quality. Using two 2835 LEDs might achieve similar or slightly higher brightness than a single 5050 LED.
• 5050 LED: These LEDs can produce 15-60 lumens per diode depending on the configuration, so a single 5050 LED could provide comparable or higher brightness than two 2835 LEDs.

2. Energy Efficiency:

• The 2835 LEDs usually have better efficiency (lumens per watt) compared to the 5050, meaning they can achieve higher brightness with less energy.

3. Heat Dissipation:

• Two 2835 LEDs would distribute heat more effectively compared to a single 5050 LED, which might have more concentrated heat due to the higher power density.

4. Flexibility and Design:

• Using two 2835 LEDs provides more design flexibility, allowing for better spacing and more uniform light distribution.
• A single 5050 LED may be more compact and simpler to install but might not distribute light as evenly.

5. Cost:

• The cost might vary, but generally, 2835 LEDs are more affordable and widely used, which can help with cost efficiency.

Conclusion

If the goal is to achieve higher luminous efficacy and better heat distribution with flexibility in design, using two 2835 LEDs might offer an advantage. However, if simplicity, compact design, and higher output from a single source are priorities, a single 5050 LED could be more suitable. Ultimately, the choice depends on the specific requirements of your lighting application.
