LED downlights are a common lighting choice, valued for their sleek design and versatility, making them the preferred option for many households and commercial spaces. However, selecting the right LED downlights is not an easy task and requires consideration of various factors. This article will guide you on how to correctly purchase LED downlights to meet your lighting needs and personal preferences.
Determine the Usage
Before purchasing LED downlights, it’s essential to determine the specific setting where you intend to use them. Are they for residential living spaces like the living room or bedroom? Or are they for commercial spaces such as offices or shops? Different settings require different types of LED downlights, so clarifying the usage will help you make a better selection.
Consider Lighting Effects
Some sellers provide images or videos of lighting effects under different beam angle conditions for reference. Common beam angles include 45°, 60°, and 90°, each producing noticeable differences in lighting effects. Using LED downlights with smaller angles will create narrower light beams, while wider angles will provide broader coverage. Additionally, consider the overall brightness of the LED downlights. Lumens per watt is an important indicator reflecting the energy efficiency of the fixture. However, a high lumen per watt ratio doesn’t always mean better, as excessively bright fixtures may lead to higher Unified Glare Rating levels
This is a reflector, an accessory for LED downlights. Its shape determines the beam angle parameter of the LED downlight.
Pay Attention to Size and Shape
While some people value the exterior design of LED downlights, most LED downlights on the market are recessed. After installation in the ceiling, only a small part of the fixture will be visible. Therefore, it’s not recommended for buyers to excessively focus on the exterior design. Typically, sellers provide parameters such as diameter and corresponding cutout diameter of the fixture, so finding the right diameter is sufficient.
Here is an example of an installed LED downlight. For users, the bottom of the downlight is not visible.
Consider Dimming and Color Temperature Functions, as well as Driver Parameters
If LED downlights can be adjusted for dimming and color temperature, manufacturers will specify it. Otherwise, these functions are not included. Also, make sure to check the LED driver specifications, including factors like power factor (PF), input voltage, and output voltage. Additionally, consider factors such as power efficiency and warranty coverage.
