Description
The Cool-tube Reflector is designed to minimise high temperature issues/heat stress by delivering an efficient and effective lighting solution for optimal plant growth. Available in two sizes -125mm and 150mm, they're suitable for H.I.D lamps up-to 600W, and deliver:
- Heat Reduction: Designed with a reflective surface and an air-cooled design, the Cool-tube Reflector helps dissipate heat generated by grow lights, preventing excessive heat buildup and ensuring a comfortable environment for your plants.
- Improved Light Distribution: Reflective surface maximises light output and directs it downwards towards your plants, ensuring uniform light distribution and promoting even growth.
- Enhanced Energy Efficiency: By reducing heat, the Cool-tube Reflector allows you to place your grow lights closer to your plants without risking heat damage, improving energy efficiency and reducing electricity costs.
- Versatile Use: Compatible with a wide range of grow lights, including HID and LED systems, making it suitable for various indoor and outdoor growing setups.
- Durable Construction: Constructed from high-quality materials, the Cool-tube Reflector is sturdy and long-lasting, providing reliable performance season after season.

How to use
Connect ducting to both ends of the tube so your extraction fan pulls air through it and carries the lamp's heat out of the grow space. Choose the size that matches your ducting and fan. Because less heat reaches the plants, you can hang the light closer to them.
For sizing the fan, see our guide to fan and carbon filter sizes. Fans are in inline fans.
Questions
Which lamps fit a cool tube?
HID lamps up to 600W.
Do I need a fan with it?
Yes. The tube only cools when air is pulled through it, so connect it to ducting and an extraction fan.
Is a cool tube worth it?
It is a good fix for heat problems if you are not ready to move to LED lighting.
