I'm trying to wire together some red and blue LEDs into a grow light. I'm thinking of 8 parallel rows of 5 350ma LEDs in series. Each series row might need one LED of a different voltage, 3.3v
The only power supply I can find on mouser that plugs into a (US) wall outlet is 16v DC 2.4A @47W.
Is this wall wart powerful enough to comfortably supply 40 LEDs?
each series:
2.4v * 4 + 3.3 * 1 = 12.9 v
each parallel:
.350 A * 8 = 2.8A
This would result in the LEDs only being slightly dimmer than their top rating if the 2.4A power supply is trying to deliver 2.8A to the whole thing, right?
I can't seem to find the right kind of power supply, so I'm wondering what values are fungible or if my math is wrong.
