When you walk into the store to buy LED bulbs, you should care about some important information about the bulb before buying. This will help you pick up LED bulbs with good quality, just like LED T8.

When shopping for bulbs, you're probably accustomed to looking for watts, an indication of how bright the bulb will be. The brightness of LEDs, or LED panel light, however, is determined a little differently. For example, an LED bulb with comparable brightness to a 60-watt incandescent is only 8 to 12 watts. But don't bother doing the math -- there isn't a uniform way to covert incandescent watts to LED watts. Instead, a different form of measurement should be used: lumens. You can always count on incandescents providing a warm, yellowish hue. But LEDs come in a wide range of colors. The popular colors available for LED T8 are "warm white" or "soft white" and "bright white."

Warm white and soft white will produce a yellow hue, close to incandescents, while bulbs labeled as bright white will produce a whiter light, closer to daylight and similar to what you see in retail stores. Anyway, no matter what kind of LED T8 you want to buy, you should pay attention to these two things.
