Ensuring Color Temperature Stability in Linear Light Outdoor

In our ongoing quest for delivering top-notch illumination solutions, Win-E Illumination is committed to addressing common concerns in the realm of LED lighting. Today, we delve into a critical aspect—how to safeguard the color temperature of waterproof LED linear light outdoor without the use of lenses. Our focus is on providing insights into a reliable method that combines performance, durability, and weather resistance.

Previous Challenges:

As previously discussed, when waterproof aluminum LED linear lights without lenses are filled with glue, there is a tendency for the color temperature to shift. Typically, this shift results in an elevation of the color temperature compared to the original chip’s specifications. The extent of this elevation is contingent on the lamp’s inherent color temperature and the precision of testing instruments.

Lens Impact:

While adding a lens can mitigate noticeable shifts in color temperature, it introduces other considerations. The efficiency of light generation may be affected, and in some instances, the waterproofing capability of the glue may be compromised. Additionally, the quality of the lens plays a pivotal role in protecting the lamp beads; subpar lenses are prone to yellowing and cracking, potentially leading to water ingress.

Innovative Solution: 5050 Waterproof Lamp Beads

To tackle the challenge of color temperature stability without the use of lenses, Win-E Illumination recommends employing waterproof lamp beads. A prime example is the 5050 high cup (2.6mm) black surface outdoor waterproof lamp beads. These lamp beads elevate the standard 5050 lamp bead height from 1.6mm to 2.6mm.

Key Features:

1. Surface Blackening Treatment:

The lamp cup’s square design, combined with blackening treatment, ensures optimal light absorption and dispersion, enhancing overall performance.

2. Special Welding Line:

The use of a special welding line method enhances the lamp beads’ resilience and connectivity, contributing to a stable color temperature.

3. Advanced Encapsulation Glue:

Specially formulated encapsulation glue adds an extra layer of protection, making the lamp beads waterproof, dustproof, and resistant to UV and sulfur.

4. Wide Temperature Range:

The 5050 waterproof lamp beads can withstand hot and cold shocks, with a temperature tolerance ranging from -40 degrees Celsius to 100 degrees Celsius, undergoing 100 cycles of zero dead lights. This surpasses conventional products, which typically endure -20 degrees Celsius to 80 degrees Celsius.

Innovative Grouting Technique:

Win-E Illumination’s proprietary grouting technique focuses on covering all components except the lamp beads. This exposes the lamp beads’ surface, allowing them to retain the original color temperature while maintaining their waterproofing effect.


In the pursuit of excellence, Win-E Illumination continues to revolutionize the LED lighting landscape. Our emphasis on color temperature stability in waterproof LED linear light outdoor showcases our commitment to providing cutting-edge solutions. The 5050 waterproof lamp beads, coupled with our innovative grouting technique, stand as a testament to our dedication to quality, performance, and durability.
