I recently built a custom LED light strip for my aquarium. I used 3 cheap Chinese made flashlights. Each flashlight has 9 LEDs (bright white), which are wired onto a small circular circuit board. 27 total LED's. The flashlights run on 3 AAA batteries. I wired all three circuit boards in parallel. I used a 4.5 volt adapter that puts out 300mA. This was an adapter I already had, so I used it instead of buying a new one rated for more amperage. The light works well enough.
My friend wants a similar set-up, but bigger. His aquarium is larger than mine and needs more light. He bought 8 flashlights. Same size, same flashlight. So he has 72 total LED's, on 8 circuit boards he needs to power. I'm assuming he needs about 1.5 amps to power these?
I have a 5 volt, 1 amp adapter I'm not using. If I wire in a resistor, will this adapter work? Or is it more complicated than this? Do I need more voltage?
I have spent a couple days reading, and calculating...but still kind of lost. Any help, to shed some light, would be great...thanks.
