Ok, let's hear it!

Yes you are right but you are now running round in circles the original point you made was LED heated up a tank more than MH, that simply is not the case, in fact impossible. the LED unit would melt, the LEDS would be so inefficient due to the heat.

In your first post you said an LED heats the tank more now its "you need a heater to get it up there" bit tired did I miss read something?

So yes if you run MH you need a chiller even if you have AC, with LED you dont as they are putting no heat into the tank.

again not arguing just a friendly debate (no emotion to bloody words on a page)
