LED spotlights knowledge

Beam angle

The difference between LED spotlights and LED downlights should be mentioned as a key parameter "beam angle". Generally, 24° can be selected for home LED spotlights.

Common beam angles are 15 degrees, 24 degrees and 36 degrees. The rare ones on the market are 6 degrees, 8 degrees, 10 degrees, 12 degrees, 45 degrees, and 60 degrees. Also have polarization angle.

CCT

Color temperature is the color component contained in the light, and the unit of measurement is Kelvin (K), the larger the value. The cooler the visual tone, the whiter the light, and the closer it is to natural light.

Generally, warm white (2700K-4500K), white (4500-6500K), cool white (above 6500K).

Household CCT is generally 2700K ~ 4000K.

Power

The most frequently asked question is:

Will 8W in the bedroom be too bright? There is only one light in my toilet, can I make a 20W one? The key point is that the height is within 4m, and the power of the embedded spotlight is 6-8W for household use. Surface mounted spotlights, track lights 8 ~ 10W.

CRI

Colour rendering index is the ability of light to reproduce the color of an object. The more complete the light source, the better the color rendering. Illuminated objects are closer to their true colors. Generally, the color rendering of light above 90Ra is a high-quality spotlight.

Just remember to pay attention to the CRI ≥ 90Ra when buying lights. Generally speaking, the higher the color temperature, the more difficult it is to develop color. For chips of the same brand and type, 2700K and 3000K can reach CRI≥95Ra, while 3500K and 4000K can generally only reach CRI≥90Ra.
