In today’s construction and design industry, lighting is about more than just illuminating a space. It plays a key role in creating the right atmosphere and ensuring the functionality of a room. That’s why LED downlights are a top choice for contractors and designers looking for efficiency, durability, and top-notch performance.
At KLM, we specialize in high-quality LED downlights for all types of commercial and construction projects. In this guide, I’ll walk you through two key factors you should consider when choosing a downlight for your project: Color Rendering Index (CRI) and Correlated Color Temperature (CCT). By understanding these features, you’ll be able to make better decisions and get the right downlight for your needs.
1. LED Downlights: A Must-Have for Modern Commercial and Construction Projects
2. CRI: Why it matters for your project?

What is CRI?

Why High CRI LED Downlights Are Essential for Your Project?
- Accurate Color Representation: In spaces such as retail stores, showrooms, or offices, it’s important that colors look true and natural. High CRI LED downlights can display colors realistically, making products and interiors look their best.
- Better Visual Comfort: In the workplace, especially where people need to focus for long periods of time, high CRI lighting can help reduce eye strain and create a more comfortable environment. This is especially helpful for tasks that require attention to detail.

At KLM LIGHTING LED, we’ve always understood the importance of CRI. Since our founding in 2009, we’ve been committed to using 90+ CRI LEDs in our products. Now, we’re excited to share that we’ve started stocking and transitioning to 99+ and 97+ CRI options, ensuring our customers receive the highest quality lighting solutions available!
3. CCT: How to Choose the Right Color Temperature for Every Space
Correlated Color Temperature (CCT) is another important feature to consider. It ranges from warm white to cool white. Different spaces require different color temperatures, and by choosing the right CCT, you can create the perfect atmosphere and functionality for any area.
Our LED downlights come in a variety of CCT options, from 2700K to 6000K.
- 2700K to 3500K (Warm White): A soft yellow tint creates a cozy and inviting atmosphere. Ideal for homes, hotel lobbies, restaurants and lounges where a warm, welcoming environment is desired.
- 4000K to 4500K (Neutral White): Provides bright, neutral lighting similar to natural daylight. Ideal for offices, hospitals and retail spaces where clear, balanced lighting that is neither too warm nor too cool is desired.
- 5000K to 6500K (Cool White): Provides clear, pure white light similar to cool daylight. It is ideal for environments such as factories, laboratories and hospitals where bright, focused lighting is critical for productivity and safety.

By choosing the right CCT for your project, you can ensure that your lighting complements the function and feel of the space. For example, in a luxury hotel, you might choose 3000K downlights to create a relaxing, elegant atmosphere, while in an office, 4000K downlights will provide bright, focused light for employees.
4. Combine CRI and CCT for Maximum Effect
One of the best ways to enhance your project lighting is to combine high CRI with the right CCT. High CRI downlights ensure accurate color rendering, while the right CCT helps set the tone and functionality of the space.
