DIY LED luminaire- do I really need fans for cooling?
Building an led luminaire and want to find out if I really need to build in cooling via some PC fans? Don't wanna faff anymore than I have to...
Currently there are 15x 3w led 700ma (powered At 700ma) stuck individually on 3.5mm ram heat sinks and spread equally on the luminaire base( mdf )
Any advice welcome.
