F-series double strips first build F564B S07

Last night Santa in the brown uniform brought me new toys!
When I place an order 3000K was sold out, so I went after 10x 3500K - now I'm motivated to add photo and far reds XP-E's for Emerson on the separate driver. 5 strips per HGL-240H-48B with 2'079" heat sinks. After seeing how QB actually slightly burnt my GG at 12 inches - I'm very excited about this build that will cost me ~$1 per watt.

Very cool, glad to see that you got the heatsinks from Heatsink USA. That is going to be alot of light for very little $$$.

These heat sinks are great! It cost cheaper than regular aluminum tubes from HD for me and just as much as aluminum angles.

When I did the math I was surprised how affordable the heatsinks are from heatsinkusa. They are based out of Michigan, so they might ship to the land north of the wall.

I should clean them out and then resell them to the rest of the wildlings.

I'm still trying to wrap my head around parallel wiring with these guys. So, if I hook up only 1 strip to the driver - will it push 5A or it will limit the current somehow?

If you hook up only 1, you need to be very careful with the voltage of the driver. Use the calculator to figure out what voltage you need to set it to in order to make it draw “X” amount of current. If you run it wide open, you could cook it.
Have you read this thread? Lots of relevant questions and answers.

The short answer is that in parallel, LEDs will demand a set amount of current at a given voltage and you are the one that gets to choose that voltage by adjusting the driver. As you increase the circuit’s voltage, the LEDs wiil demand more current. You need to set the driver to output a certain voltage to make sure the LED doesn’t demand too much current. This is the opposite of constant current setups, where you have control over the
current and it is the voltage that varies on each LED.
The driver will only put out as much current as the strip wants. You have to dial that in by adjusting the voltage of the driver. You could have a driver that does 1,000,000 amps but as long as you set your voltage right, that strip will only pull what you want it to.

Got ya, thank you. Since it's a 48V driver I gotta drop couple of volts down and i'm good then!

Yessir!
