You'd be right too. And the balance of the strips could shift due the different diode resistance, different level of heatsinking etc. But it won't go in thermal runaway because the driver controls the amount of current that comes out. And as in my post it says the thermal runaway only comes into...

Yes, you would. The power supply won't give them more current that has been set. This is why it's called constant current. Though adjustable, but constant.

"It all starts with the profile of silicon. The electrical resistance of silicon increases with temperature up to about 160 Celsius, then starts decreasing. When resistance decreases, it allows more current to enter through the overheated areas, in turn causing yet more compounding heat...

Yes. And if you'd use 2 parallel circuits with equal amount of resistance, the current would be equal. If the resistances are different then the currents would be different too. You could measure the diode resistance with typical multimeter which has diode function on it. This way you could...

Ye, 100k ohms, though the 1-10v and pwm's are just as good. And same for the brands really, go by what's available and in good price. They all do they same job. When I bought mine at led-tech.de they had 3d printed casings and a knob for the component, so it ended up as very neat looking and...

Yea, I got some smaller ones of those. ELG150, ELG240, HLG320 The A versions have the potentiometer which worked for only 50-100% range and was in a bit clumsy place in bottom. But ended up adjusting them with the 1-10v

Well the thermal runaway is only a issue if you don't use constant current, which you should. I have a mix of low and high voltage versions of Meanwell power supplies, no real favourite. Depends really on the setup you are building. About mixing different strips, only thing you kind of want to...

No, the components will take what voltage(because of resistance) they need if the total voltage you supply isn't over the total voltage of your circuit. Absolutely fine running different voltages in parallel or series, when the driver can modify it's output voltage. But yes, the driver needs to...

Should work fine. The drivers automatically gives proper voltage within it's range. Just be sure that the amps are fine for each circuit.

Well the 301H is pretty great if you can get decent deal on them. I have some of those, but most are 301B's. The 281B is getting a bit old and loses on some numbers more, but price might be getting pretty low. edit: Sry, missed plenty posts about it already

I think the samsungs are best in the biz now. Then it depends on the price. There was bridgeluxes available where I bought my samsungs, but they really weren't on the same level with uMol/joule efficiency. Below is chart taken from led-tech.de for 98x samsung LM301B 3500k strip. Hope this gives...

I'm from Finland so the prices probably don't apply too well. Have you thought of doing some kind of casing? Mount the strips into a sheet of aluminium, make lid for the casing and attach a small pc fan to pull the air from the gaps. I reckon these will last decades, so I gave more thought for...

When so small plants get stunted good it can take awhile to recover. Like if some of the roots dried up previously and there wasn't much leaf mass, it takes awhile to grind up some nutrients and make up decent root system all over again in order to grow well again. On the brighter side, the...

I've 3x these kind of bigger lights with 2 of them with 10strips and 1 with 8strips. Got also some smaller ones built. First season I used 'em I had half of that so 5 and for 4 strips. 20v 2800mA full power on 5strips version ran a tad hotter than I liked. Didn't measure temp, but couldn't keep...

I'm sure they do. Just a matter of knowing how and what to trigger in order to receive certain reactions. I was thinking step ahead and about breeding. So like if you have certain insect that triggers certain terpene production, you'd keep triggering that gene over several generations, and that...
