Testing a low cost DC/DC boost converter with constant voltage and constant current potentiometers, suitable for driving high power LEDs. The driver can power a single 100W LED without any difficulties, but what about two 100W LEDs in parallel?

i recently brought this for fun projects. However, i try to use this but when i give power to vin the output shows noting 0 volt infact the power supply stops working shows 0 voltage. Did i blow the circuit or fuse or any diode?. that's not my field of work but im curious to know about this kind of stuff.
hmm just realised this is zero use for an application i had in mind as the negatives would be common.
Is it possible to provide a suitable output for the laptop input, which is 19 volts and 7 amps, with or with a 12-volt battery of the car, which is 60 amps?
Biggest, baddest LED light fixture there is, eh? For $25, I got a 126W combo flood/spot light bar, 22" long, from Ebay. ($37-$43 today) It would drive your neighbors CRAZY, Julian. I truly favor the 6500k pure white color to the after-3-pints warm urine color. LOL I'm starting to put together a 100W LED flood light with LIFEPO4, for a portable BRIGHT light.
it is rated 10 Amp. but driving output only 5 amp . because i think 10 Amp is input limit not the output limit. and at 25 V and 5 A as output we alredy taking around 12Amp input from 12 V battery
How much light are these led's actually kicking out? Can you light up your garden with a single die?
I want to see the biggest baddest LED strip there is!!! Great video!
5 amps at 36v is 15a at 12v those little wires arent meant for that :p the leads arent helping either
what are you using to power it? maybe i missed something ? not ac in hu? is it a battery?
Is it wise to put the LEDs in parallel???????????
how can you say it is reliable when the LEDs are only on for a few seconds?
why not use a flasher circuit then????
I love the way you explain things
I'm doing something similar but with driverless full spectrum cob chips and dog bowls,does anyone know how hot these chips get?
Do you know of any 30,40 or 50 LED Chips that run on a forward voltage of 9-14V? I have looked everywhere that I know of but am unable to find one. Is that something that would have to be custom made?
