Bonanza growbox with CMH lamp 315 Watt

More and more hobby growers are becoming aware of the importance of energy efficiency. The industry is looking very hard to find alternatives for the energy guzzling HPS lights. A lamp that has been on the rise for quite some time among American growers  is the Ceramic Metal Halide lamp.
Most people are familiar with Metal Halide lights and think this is a vegging light. Not suitable for flowering.
But a CMH light is not a regular Metal Halide light. Its arc tube is made of ceramic instead of quartz which is used in HPS lights. One of the qualities of ceramics is that it can stand much higher temperatures, The higher temperature in combination with the metal halide gas creates a light spectrum that’s more complete then that of almost any other lamp. In other words it resembles more the light spectrum of the sun than any other lamp.
Altough the CMH lamp works with higher temperatures in it’s arc tube it consumes relatively little energy and radiates less heat.
In short, a perfect lamp for use inside a growbox.

Plug & play grow box with CMH lamp

After lots of testing and measuring we think the time has come to launch a plug & play grow cabinet with CMH light.
We choose the Sunkraft 315 Watt lamp with dimmable Lucilu e-ballast and a Azerwing reflector with special PGZ18 lampholder.
Growing with these energy saving lights has a lot of advantages. Less power consumption also means less heat.
The combination of a good parabolic reflector and the little heat emission makes it possible to hang the lamp as close as 25 cm above the plants.
The dim function offers you the opportunity to run the lamp at 50, 60, 70, 80, 90 or 100% of its power. This makes the lamp applicable for use during every stage of the plant’s life

The picture above shows very clearly the advantages of growing in a cabinet. The measuring was done with removed doors. The measured values at the back of the cabinet are much higher then at the front side.
The values at the front will be the same as at the end when the doors are closed.
