Any one use the T-8 or T-5 LED tubes for growing? If so, How do they work?

You need to know if these LEDs produce the right spectrum for plants, since plants need mainly include red and blue (magenta purple) hues for photosynthesis. If only gives white light is hard to accomplish this.

This video shows an LED lamp on and you see the colors that have the lamp.

Hi, T8 and T5 are fluorescent bulbs. LED lights are completely different. The LED lights are the up and coming grow lights, but many people have been using T12's, T8's and T5's for years with great success.
