Led to shoot the light, how much is seven bubble of v
Search you said 7 outside lights, you can use the 24 v measure. In short don't exceed the limit of the current largest, there is no problem. Just a little bit small current is not bright or not bright. There will be no other problems.
Due to the led constant current drive better. If direct use direct current (dc) according to the lamp bead by up to 85% of current TV university. Current or high voltage droop dawn soon.
If the lamp bead (except the red light) is connected in series is about 21 v. A single light red beads of voltage is 2.1 V - 2.3 or so. In addition to the red light of the other is 3-3.5 V.
