All Light Emitting Diodes (LEDs) are not created equal, and it's important for the consumer to distinguish quality lamps from sub-par product. At a very minimum, consumer företagsskyltar  need to understand basic terms. The following LED related terms are a good start:

Efficacy- With high end and commercial grade products, efficacy will often be listed on packaging or on a cut sheet (information sheet). Efficacy is defined as lumens per watt. The higher a lamp's efficacy, the more efficient it is. Look for numbers higher than 80 in PARs and A19s and higher than 90 (or higher than 100 in the case of new technology) in LED tubes and panel lights (wall packs, security lights etc.). A higher efficacy equates to doing more with less, greater lumen output with fewer watts.

Kelvin- Kelvin temperature, or Kelvin, actually refers to the color a lamp provides. More specifically Kelvin refers to the color emitted by the diodes inside the LED företagsskyltar  lamp. Lower numbers indicate a warmer (more yellow) color, while higher numbers indicate a cooler (more blue) color. Daylight white tends to be 5000-5500K. Spaces lit with incandescent lamps tend to range between 2400 and 2700K. In my experience, clients who have been working under fluorescent or incandescent lamps are initially most comfortable with 3200-3400k. That being said, color does have an effect on productivity. 4100-4500K tends to be most pleasant and to have an energizing effect.
