I have ordered a growth light for my plants. Only later did I realize that it said its a 2kW light, which seemed quite excessive as it is only the size of a small keyboard and not that densely populated with LEDs. So I did some digging and figured out that it is using 2835 model LEDs. I found a website where I can buy those "by the meter". The website states that with 120 LEDs/meter it will use 24W/meter. My growth light has 216 LEDs. Lets round that up to 240. This would mean it uses 48W and not 2kW. What could be the cause for that difference? Is this related to the equivalent for a non-LED based growth light?
I looked up some generic LED light I can buy in a store near me and there you can also find some weird wattage conversion:
4.6W = 35W is what I am talking about.
