FULL SPECTRUM

Promotes plant growth. Give your plants full spectrum light they need during the vegging and flowering stages. How do plants use light during photosynthesis? Red light spectrum enhances the flowering and blooming stage, along with seed germination. Blue light spectrum boosts chlorophyll to grow strong stems and healthy leaves.

As expected

The item was as advertised. I am a week into use and my first seedlings are on their way out of the soil.

Terrific product

These are terrific fixtures/lights - lightweight, easy to set up, excellent lighting for plants (I am using them to start seeds indoors for my garden). Clean design, excellent price, too. So much better than the old fluorescent fixtures I've used in the past! Customer service was wonderful--the first package sent somehow went astray, and they responded immediately and sent another order. Very pleased with the product and my experience with Sunco.

Sunco Grow Lights

I’ve replaced a fluorescent light source with 2 Sunco LED grow lights and so far my tomato seedlings have responded very well to the Sunco lamps. Both lights are linked together and connected to a timer. I like this linking feature. It eliminates the need for extra extension cords and outlets. Overall, I give this product 5 stars.
