315w Horizon Daylight Remote Reflector

The Maxibright 315W Horizon Daylight Remote Reflector is a high-performance lighting shade designed to maximise the efficiency of 315W CMH/CDM grow lights. Engineered to deliver a wide, even spread of light, this reflector helps distribute usable PAR across the canopy so plants receive consistent illumination throughout the grow space.

Built with excellent construction quality and designed specifically for ceramic metal halide systems, the Horizon reflector helps growers make the most of the natural, full-spectrum output that CMH lighting provides. This balanced spectrum supports strong vegetative growth, improved plant health, and productive flowering in hydroponics systems, coco, or soil setups. Its wide-angle design also makes it particularly effective in grow tents or grow rooms where even light coverage is essential for maintaining a consistent canopy.

As a remote reflector, it connects to a separate CMH ballast, allowing the ballast to be positioned away from the canopy to reduce heat around plants.

How It Solves Grow Problems

Uneven lighting in a grow tent or grow room can lead to inconsistent plant development, with some plants receiving too much light while others remain underlit. The Horizon reflector spreads light across a wider area, helping create a more uniform canopy.

This improved distribution encourages balanced vegetative growth and stronger plant structure while supporting better nutrient uptake and flowering development. By placing the ballast away from the reflector, growers can also reduce heat around the canopy, helping maintain stable temperatures and reducing plant stress during the bloom stage.

How to Use

1. Install a compatible 315W CMH lamp securely into the reflector socket.

2. Hang the reflector above the plant canopy using adjustable hangers.

3. Connect the reflector to a 315W CMH ballast using the correct lead.

4. Place the ballast outside the grow tent or away from the canopy where possible.

5. Connect the ballast to a suitable power supply.

6. On first use, allow the lamp to run continuously for at least 15 minutes to stabilise the lamp.

7. Adjust the reflector height as plants grow to maintain even canopy coverage.
