nodemcu is suffering from severe memory insufficiency due to too many features being included in the firmware, imo - thus i needed to compile everything to lua bytecode before it worked for me.
I use 3 strip of 3,6mt for every channel, but we can consider little more than 2 strip of 5mt for every mosfet (total 10mt). This is specs of led strip :
Working input Voltage : 12VDC , 6A
Working power : 72W/5M
this mosfet has a continuous drain current at 5v of 36a.... but at 5v... and at 12v ?
If it isn't good for this charge do you know another mosfet more powerful ?
And other thing :
in my project i have connected esp to her little power source , source of mosfet n.1 to -12v of powersupply n.1 - out of mosfet to minus of led strips and powersupply +12v direct to plus of led strips.
Same thing for mosfet n.2 leaving power supplies indipendent.
Is this correct ?
I think the irlz44 can handle this high load only with good cooling, if at all. You could try to use two mosfets in parallel per channel, or you need bigger mosfets, or even SSRs.

Thanks Dennis,
From the beginning i've cut a dissipator from an atx old power supply, so i don't think that it depend from cooling.
Two mosfet can be a good idea, but bigger mosfet like what? i've no idea about mosfet code ... do you know one bigger?
And, excuse me, what is an SSR?
EDIT : ok solid state relay... but for dimming purpose ???
