5730led hard lamp, with one meter long and 72 beads, what is the power?
In fact, hard light with more use of low voltage, 12V or 24V, the use of resistance to limit the current, then add the actual resistance loss, more than 40W, but with such a high light power is not enough, because the heat problem, up to 20W, safety should be controlled in 10-15W.
This is actually very difficult to calculate, because the current and voltage using the actual do not know, if the maximum value is 5730, each 0.5W, current to 150MA, when using high pressure constant current drive, the 72 is 36W
