Re: Where is my other 100 watts?

What size wire did you use? That's a sharp drop for such a short run. Also measure at the immediate output of the driver. If it is indeed too small wire the proper fix would be to redo everything with thicker wire. Another possible fix may be to move one of the supply wires to the other side of the...

Re: Where is my other 100 watts?

Strange. Can you hook up an ammeter? Measure the voltage at the last strip? Voltage loss due to the wire comes to mind but you're measuring 23v which seems well within the tolerances. I am showing 23v when I measure from the out terminals of the first strip. There is a slight and steady decline as ...

Re: 1” heatsink comparison pics/details. HeatsinkUSA VS Chinese

No background in metallurgy, beyond an obsession with knife steels... There is a difference in heat dissipation between different aluminiums, although they are usually not included in heat sink calculations. Anodization also improves dissipation. I'm pretty sure the main factor is surface volume, s...
