I've just fitted the following 400w cooltubes which are used in the Hydroponic scene for gardeners.
Having spoke at length to the company they assure me that when used with a fan and ducting the system will remove 95% of heat from the halides. Thats got to be a good thing and "maybe" save on a chiller.
My setup starts with an intake to the fan in the house loft through a 6" fan then 6" ducting, through 3 by 400watt cooltubes then outlet is ducted to the outside.
You can also search for them under the term Suntubes
