What is the actual power draw and light output of these fixtures?

Each 4-foot fixture consumes 40 watts of power. They utilize efficient LED chips to produce a full-spectrum light output that is ideal for all stages of plant growth, from vegetative to flowering. This provides strong, usable light for plants while keeping energy costs significantly lower than traditional fluorescent or HID grow lights.

How do you link multiple lights together?

The lights are designed to be linkable. Each fixture has connectors on both ends. You simply plug the power cord of the first light into an outlet, and then use the included link cables (or compatible connectors) to plug the second light into the first, daisy-chaining them together. This allows you to power multiple fixtures from a single outlet.

What is the recommended hanging height for different plants?

The recommended height varies by plant type and growth stage. For seedlings and young plants, hang the light 12-24 inches above to prevent burning and encourage strong stems. For mature vegetative and flowering plants, a height of 18-30 inches is typically suitable. Always monitor your plants for signs of light stress (bleaching) or stretching (reaching), and adjust the height accordingly using the included hanging cables.

Can I use a timer with these grow lights?

Yes, absolutely. These lights plug into a standard wall outlet. For optimal plant growth cycles, we highly recommend using an external mechanical or digital timer. This allows you to automate the photoperiod (e.g., 16 hours on/8 hours off for veggies, 12/12 for flowering), which is crucial for plant health and development.

Are these lights suitable for a full hydroponics system?

Yes, these full-spectrum LED lights are an excellent choice for hydroponic systems. Their efficient light output supports robust growth for leafy greens, herbs, and many fruiting plants in a hydroponic environment. The linkable design is particularly useful for illuminating longer NFT channels or multiple Dutch bucket systems. Ensure your setup allows for proper mounting above the water culture.
