Can I use the dim function for climate control?


Light is responsible for photosynthesis and dimming the light will decrease photosynthesis and ultimately your yield. If you are not over-saturating your plants with light then you should try to keep your climate under control. Over-saturation already happens at 60cm from a Philips 1000W DE lamp, so keeping the right distance is also a good idea. Keeping the lamps at some distance and overlapping the throws increases uniformity of the light and decreases the intensity of the infra red-by streading it. 

Plants that evaporate water also have a positive influence on the climate in the room. When they stop doing that as a result of over-saturation you not only harm your plant but will also influence the climate negatively. 

Fast moving air causes the plants to evaporate faster which is not a good idea when the temperature is really high. It would cause the plant to stop evaporating, basically shutting down the cooling system of the plant causing the leafs to burn. 

So light control should not be used for climate control purposes. If it frequently becomes too hot in your climate room then you should improve your climate control. However, in extraordinary weather conditions it is better to keep keep the plants cool to prevent damage, so as a necessary evil you should then dim your lamps.   

Dimming lamps is not climate control: it is damage prevention.
