Lightspeed Pro LED Cosmic 400W

Are you willing to see Lightspeed’s effectiveness when it comes to the next generation of LED’s?

Lightspeed Pro Cosmic LED 400W is a high-intensity, full spectrum LED grow light that delivers powerful photosynthetic lighting to stimulate vigorous indoor plant growth.

Specifically designed for cannabis culture, this 400W hydroponic grow light is ideal for delivering a targeted light spectrum to optimize plant propagation during the growth phase of your crops.

Lightspeed Pro Cosmic LED 400W features many technological innovations designed to help you increase your hydroponic yield, lower operating costs, and improve your bottom line.

This advanced full-spectrum LED grow light generates well-balanced, natural light distribution that is more uniform than HPS and MH lighting.

It also includes a dimmer that puts you in precise control of light illumination exactly when you need it. This is critically important for growing fragile seedlings, avoiding damaging sensitive plants, as well as extending the life of this grow light.

The fixture’s vertically-compact design enables you to build space-saving tiered growth setup and only requires a minimum distance of 30cm (11.81”) above the canopy. Lightspeed Pro Cosmic LED 400W can run on a power supply range of 100V to 277V, giving you several electrical connection options. Simply plug it in and enjoy prolific plant growth!

This fixture is compatible with our Lightspeed Pro HID & LED Universal Controller.
