Hello, Friend,

Here i'd like to tell you someting about the LED Light Bead.

Here is the input voltage of the leds: 3.2V - 3.4V:     Blue  /  White  /  UV

                                                                  2.2V - 2.4V:  Red / Orange / Yellow / IR / Green

For example:   the 3W chip leds: 3W blue 460nm leds ,  its'  theoretical power consumption is about 3W.

                           the 3w chip leds: 3W red 660nm leds, it's theoretical power consumption is about 2W.

Let's calculate:

The 3W blue led's input voltage is 3.2V - 3.4V,so just about 3.3V, set the current for 800mA = 0.8A, so the power consumption is:  3.3V * 0.8A = 2.64 Watt.

The 3W Red led's input voltage is 2.2V - 2.4V,so just about 2.3V, set the current for 800mA = 0.8A, so the power consumption is:  2.3V * 0.8A = 1.84 Watt.

But, actually 0.8A is so high current,high current cause high power, high power cause high heat, so high heat will reduce the lifespan of the leds, so , super high power is not a wise choice.

So, usually we set lower current:  600mA or 520mA, so the actual power of the Blue leds is: 3.3V*0.6A = 1.98Watt.   and the real power of the  

So, usually we just set the current 600mA or 520mA.

The actual power of the Blue 460nm leds is about 3.3V * 0.6A = 1.98 Watt . So, that's why a auqairum lamps  165W(55x3w) also called 120W. (usually the auqarium lamps is built with  blue and white leds , their both power can be about 2W.)

The actual power of the Red660nm leds is about 2.3V * 0.6A = 1.38 Watt . the fans is about 2W/pc.  For the grow lamps, let's calculate, if the  80x3w is built with 60red and 20blue leds, the power should be about:  60*1.38 + 1.98*20 + 6w =  123W . 

Actually, in my company , the best 80x3w can be 125W - 130W.  

Just feel free to contact me for higher power lamps and best design lamps.
