Does anyone recognize these LEDs? Are they the 5050 kind? There are 5 sets of 3 leds on one strand. I have 2 strands of these that I want to connect together, but they don't say the voltage or amps anywhere written on them. As far as I can tell by experimenting with 12v power adapters, they must be 12 volts. I have different Amp rating 12v power adapters ranging from 200ma to 1000ma. Would 1000ma be too high for these two strands connected together?
