By Comparing LEDs to fluorescent tubes, there are four key specifications you should review:
1. Watts- This is a unit of measurement for power consumption. Four foot LED tubes typically use 15 to 25 watts, while fluorescent tubes use more than 30 watts.
2. Lumens - This is the unit of measurement for strength of light. Look for tubes with 1500 lumens or more.
3. Color temperature - The temperature of the light is the color of the light. It is measured in units of absolute temperature, or Kelvin (K). 3000K is considered warm (redder), 4100K is considered neutral, and 5800 K is cool (bluer).
4. Lifespan - This is how long the bulb will last. It's measured in hours. 50,000 hours is common for LED tubes.
