And if you are saying that it is getting hot quick, it might be gunning those pretty hard. Might even be able to squeeze out more with just simple spring bypasses.

edit - actually in some Taobao links, i am seeing some 7070 emitters rated at 6V 5A. So yes, 30W per emitter. There are some which are 15W, 18W though.

Some folks here might even be able to swap those chinese 7070s out with their spare XHP70s within 10 mins or so, don’t even need to change the drivers if they are driving the LEDs decently hard, meaning that with XHP70s the light would be putting out more light while running cooler. The possibilities……

Then next week after the holidays i might try to get it for under rmb 300. :smiley: Maybe tomorrow even (most of them are already working esp on TB), counting on you Sillen!
