Energy efficiency

Like any 2 feet long T5 grow light each of these bulbs will chew up only 24 watts making them extremely cost efficient. And when we take into consideration that each of these bulbs are able to give out 2,000 lumen of light that makes these replacement T5 bulbs also very energy efficient.

Color temperature

The color temperature of the light that these bulbs produce is 6,500 Kelvins which means that the light will closely resemble the light that can be seen on a sunny day making the bulbs perfect for plants that are in their vegetating stages of their growths. However because this color temperature is close to the color temperature of sunlight these bulbs will also benefit seedlings and cuttings as well as cloning of the plant. And they can even be used as aquarium lighting.

Life expectancy

These lights are rated to be able to burn for about 20,000 hours. Of course there always are factors that can shorten or prolong the lifetime of bulbs but if you will be careful with them they will almost certainly work longer than 20,000 hours.
