Cooltube 5" Complete Light Kit
These lighting kits feature the Coolshade reflector which is arguably the most effective air-cooled reflector on the market. Its simple design enables extremely efficient air throughput and great cooling. The reflector has been recently redesigned to include a reflector attatchment that better spreads the light. To use this reflector you would need to employ a suitable extractor fan. Which fan to use would depend on how you intend to use the Coolshade.
