LED light Lamp COB chip

[Justice]

So i want to take 12-15 led light chips and connect them all in parallel to make a very bright light. my question is would the set up i was planning on using work? just wanted to get more professional opinions first. Any suggestions would be greatly appreciated. I was planning on connecting a 12v car battery to a DC DC step up converter, one for each light chip, then connecting them individually to the lights. I will also be mounting this on heat sinks as well with thermal grease. Will this work or do i need more power? Here are the lights and step up i planned on using, i am very lost in this subject field i apologize so please help.

The LED uses 3000MA, that is quite something. It is more likely to be 3000mA or 3A.
The LED consumes 93W, that is 8A at 12V which is about as much as you should take from a car battery unless you want the light for a short time.
The booster will run without an aditional heat sink but the light will need a heat sink capable of dissipating 93W.

To multiply this circuit by 12 will need a hell of a battery

So say i did want t power 12 of them for say 10 minutes at a time max. Would there be any practical way to do it? I found a video similar to what im looking for just for an idea

Thank you for the help

Apart from what Duke37 said, your booster is maxed at 32V.
One LED is 32 to 34 Volt?
You are already trying to drive a hard bargain!
