The Cooltube Glass Reflector is a heat dissipation system that comes from light fixtures. In this way, you can bring the lamp closer, enhancing the yield at the end of the branches and reducing the cultivation temperature by several degrees.

This system guides the exhaust air through the bulb, drawing away much of the heat it generates. The tube remains cool, and the temperature is stable.

It needs to be paired with an air extractor.

Available in sizes of 125mm and 150mm.

Uses and Dimensions

The Cooltube Glass Reflector is a reflector specifically designed to draw heat away from the lighting fixture directly from the bulb, linking to the extraction system. This process removes a substantial amount of heat from the bulb, which leaves the tube cold, allowing it to be positioned closer to the plants, thereby decreasing the overall temperature of the cultivation. This enhancement will positively affect the plant's performance, especially at the tips.

  • Enhanced plant performance. 
  • Lower temperature in cultivation.
  • Better temperature control.
  • Economical.
  • High heat resistance.
  • Resistant to humidity and prolonged use.
  • Can be attached to the standard light kit of the cultivator, using bulb and ballast.
  • Now comes with an external reflector for the same price.
  • An air extractor is needed to accompany it.


  • 125mm, suitable for halide or sodium bulbs from 400w up to 600w or CMH LEC.
  • 150mm, recommended for 600w bulbs.
  • Compatible with CMH LEC.

La Huerta's Opinion:

The Cooltube Glass reflector is an effective, practical, and economical system for enhanced temperature control in indoor cultivation.

During the assembly, it's advised to not let air pass through the seal as it may cause the spread of bad odors. It's necessary to remove the protective plastic sticker that shields the reflector before initial use.

This can be highly recommended to indoor, tent, greenhouse, or grow room cultivators. Discover more lighting solutions right here at La Huerta Grow Shop.
