To most of the Apollo LED grow light end users, how to calculate its actual power is a very important but interesting and easy entertainment, and I think it is necessary to mention it here again.

First,we should now how to calculate the power of a single LED chip, theoretically, power=input volt X input current. For instance, a LED chip input current is 300 MA, input volt is 2.4 V, its theoretical power is 2.4×0.3=0.72W, and this LED chip has been being claimed as 1w LED chip for several years.
In fact, LED chips should not be defined as how many watts they are, they should be defined as how large they are, such as 24 mil, 38 mil, or 40 mil, 42 mil and 45 mil. The larger the LED chips, the larger their tolerance for the input volt and current, so that they can be built as large power. Obviously, if a 38 mil LED chip, we build it as 3.6V input volt and 600 MA current, its theoretical power is 3.6×0.6=2.16W, but its tolerance will be weak and it can be burnt out in the next few months, so this is also the fundamental reason why some LED grow lights easily get light decay or burnt out. Just like we ask a little child to do a grown-up job,he might be able to finish it, but the result is he will be destroyed or got overwork problem.
But, unfortunately, most of the LED grow light manufacturers are using 38 or 40 mil LED chips to build their products, especially those little and irresponsible start-up workshops. Such as a claimed 288x3W=800W LED grow light, we can easily to analyse whether its actual power is true or not by asking its input volts and current.
Apollo LED grow light, built with 45 mil LED chip, its input volt is Red,Orange,Yellow=2.6-2.7 V, input current is 700AM, single LED power=1.82-1.89W; Blue, Green, White and UV=3.6-3.8V, input current is 700Am, single LED power=2.52-2.66W.
Now,for example,let’s calculate the Apollo 8 LED grow light built with 120 pieces LEDs, spectrum ratio Red 65%, Orange 15%, Blue 20%, 78 pieces Red LEDs, 18 pieces Orange LEDs, 24 pieces Blue LEDs.
Red LED power=78×2.6×0.7=141.96W; Orange LED power=18×2.6×0.7=32.76W; Blue LED power=24×3.8×0.7=63.84W. So the total power of the Apollo is 141.96+32.76+63.84=238.56W.
Now,you may wonder,why do we mark our Apollo 8 as 266-278W? Because 238.56W is only a theoretical power,we know, while an equipment is running, it has an inner consumption. It also depends on the LED drivers’ conversion rate, our patented LED drivers’ conversion rate is 90%, so the LEDs power is 268-278×90%=241.2-250.2W.
Some users might be very interested in figuring out their spectrum ratio, but to know how to calculate the power is not enough. Because the Apollos out put voltage must be less than 45V DC- the Low output technology is also only enjoyed by the Apollos, no one has this technology in the high power LED grow light class.
So, the most quantity of 3.8V LEDs at each module is 5 pcs, more than this, the output voltage will be higher than 45V. For example: 10×2.6+5×3.8=45V, it is the limitation. How about 11 pcs Red and Orange, 4 pcs Blue? 11×2.6+4.3.8=43.8V.
To consider a long lasting performance, each orb’s output voltage must be equaled. But how to balance this? The easiest way to do so is to build the same spectrum LEDs at each orb. Especially to the IR LEDs, if you add 1 IR LED in one module, the other modules must add 1 IR LED as well. But the same input Voltage LEDs can be exchanged by each other at different orbs.
By the way, you may think: Every manufacturer can build their LED grow lights with 45 mil LED chips and build their products as high input volt and current,it is very easy. Yes, you might be right. But you must consider the price cost of the LED chips. A piece of 45 mil LED chip is far more expensive than a piece of 38 or 40 mil LED chip.
Price cost is only a main reason why they don’t choose larger LED chip, the secondary reason is the thermal problem. If the thermal system cannot discharge all the heat emitted by the LEDs, the inner temperature of the LED grow light will get problem, light attenuation or LED chips burnt out are common.
The Apollo LED grow light built with efficient thermal system, its inner temperature will never be higher than 60 degrees Celsius, to it will never face the light decay or LEDs burnt out problem. And only the Apollo LED grow light can be built with so effective thermal system.
