The Cooltube 150mm is a large-format glazed reflector designed for HPS and MH lamps from 400W to 600W. Its wider 150mm diameter allows greater airflow, essential for effectively dissipating the heat generated by high-power bulbs. The go-to cooling solution for 600W grows in confined spaces.

With its two 150mm flanges, the Cooltube 150mm integrates directly into an extraction or forced ventilation system. Airflow passes through the glass tube around the bulb, captures the heat and vents it out of the grow room. The result: a significantly lower temperature under the lamp, without compromising light intensity.

The reflector features a high-reflectivity hammered steel housing and a transparent borosilicate glass tube that transmits the full light spectrum. The universal E40 socket accepts all types of HPS and MH bulbs on the market.
