Finding the right light bulb for your home can seem difficult. You may notice that each bulb comes with a lighting facts label with different information about each bulb. This information is extremely valuable but not everyone fully understands it.

The Lighting Facts label is designed directly after the Nutrition Facts label and mandated by the Federal Trade Commission. With the information provided, we will help you to understand each part of the label so you can select the perfect light bulbs for your needs.  

How Does Packaging Affect LED Lighting?


LED TubeLED packages are simply the outer packaging, i.e. the assemblies that are home to LED chips. These are crucial LED components, allowing the actual light emitted to stay connected with the energy source, while safeguarded in a secure unit. Other purposes include shielding the LED chips and the wiring from any hazards in the surroundings, defending the chip using high quality phosphors and silicone resin, and ensuring continued flexibility and standardization of future lighting products.

There are a number of different LED packages used for modern industrial LED lights. And of course, each of them have their own advantages and disadvantages. If you are buying LEDs for your office, business premises, or factory settings, we can help you select the right LED bulb, along with the perfect packaging for your needs.

Color Temperature Explained

LED Color TemperatureSurprisingly, the color temperature of a light bulb has nothing to do with how hot the bulb gets! Color temperature is actually a method of describing the color characteristics of light. LED color temperatures have various ranges, including Warm, Cool, Natural and Daylight. Each color temperature has its own distinct look and feel. The color temperature is measured in Kelvins (K). The higher the Kelvins, the cooler the temperature, and the lower Kelvins, the warmer the temperature. The range for Kelvins for LED lights is from 2700K to 6500K.
