I have a set of Marine Linear Strip lights under my gunwales. Each light has 6 LEDs. The box said: Voltage/Draw: 40mA. I tried to Google the conversion and couldnt find a clear answer. I got the impression that I divide by 1000. If so, 40mA = .04 amps. Is that correct? Thanks

You are correct 1000 milliamps = 1amp

Thank you.

I was just curious because I had some underwater lights that draw .5 amps each on the same circuit. I had problems with the underater lights and OceanLED is sending me new ones. I told them that the deck lights were on the same circuit. However, a combined total of 1.08 amps is nothing on that circuit.

The prefix "milli" generally means 1/1000th.

I am an electrical engineer by trade, now retired. Nevertheless, the low current draw of LEDs never ceases to amaze me. It's like it violates some fundamental precept of conservation of energy - you do get something for (almost) nothing.
