These critters are pretty small. They are designed to work on 12 or 24 volts. 8-amperes is almost 100-watts. Yes, you too can have other than Wal-Mart parking lot grade (amber) lighting, and dim to whatever you wish to (there is a limit). And PWM does not eat power like a resistor, or rheostat.

Last year car/tent camping I used one of these plus a pair of 12V 10W LED floodlights on a pole and a 12V 8AH SLA battery to light up our campsite.

Got two and they're great. The cooler one is an in-line module that runs from an RF remote complete with presets for around 8-10 bux

I've got one of those on My bedtime reading light, but I stripped the guts from the Box to fit inside my light. Bought it on Amazon for ~5 bucks, free shipping.

It has no Heatsink.

It works well on my Sub 0.1 amp LED reading light. I feel the dimmer light allows me to fall asleep faster.

When used to control a 1 amp 92mm 12v muffin fan, the muffin fan whined at slower speeds.

I got a 25khz 10a pwm controller that lowers the fan speed without whining, but curiously when powering some CREE LED's, the LED's whine when dimmed.

They are available for less if one searches. I first bought this model from Ebay, but it came horrendously packaged and was missing the parts for attaching the wires. They sent me another, and now I have 3.
