Cooltube B1 incl. reflector and 5m cable, 150mm diameter, 490mm length

The Cooltube reflector is a great helper for all indoor growers. The bulb is placed in a sealed tube made of borosilicate glass, which allows air cooling. This helps you avoid burning the plant tops, and the Cooltube can be positioned lower than standard reflectors. Using the Cooltube reflector, you can remove up to 90% of the heat generated by the bulb from your grow room. The borosilicate glass does not affect the light spectrum. The reflector, which is built directly onto the tube, is made of hammered aluminum with a Hammer finish. Dimensions of the Cooltube reflector: 150 x 490 mm. The Cooltube B1 reflector is suitable for bulbs from 400 W to 600 W. By using the Cooltube, you will extend the lifespan of your bulbs and maintain optimal temperature in your grow room more easily. E40 socket. For hanging the reflector, we recommend using SunGrip crane hangers. Supplied including a mounted connection cable with a length of 5m.
