iPower T5 Grow Lights, 4ft 6400K High-Output Fluorescent Tubes, Grow Light Fixture Bulbs for Indoor Plants, Hydroponic and Greenhouse, with 2 Hanging Cables, 10ft Power Cord

   The bulbs included with this T5 fixture are 6,400K color temperature which are most beneficial to plant that either have just started to sprout or are already growing. But if your plants are already in their blooming stages of their growth then you can replace these with 3,000K bulbs to give the plants warmer light that is better suited for flowering.

   T5 grow light possesses reflectors that are able to reflect about 95% of all emitted light back to the plants making this fixture more efficient. Two switches allow you to turn on only 2 of the four bulbs at a time, giving you the option to variate the light output. The daisy chain feature that allows you to plug together multiple T5 lights and power them all from one outlet so you don't have a clutter of wires taking up space in your indoors gardening space.
