BillyIdle said:Should have had a little more cash than I have atm., cause then I could order the LEDs you use, and compare to those I have now According to the calcluations you did on my LEDs earlier in this thread, my new layout will output 210 lumens, while yours was 50000+. Thats in the 250x brighter ballpark, even though you have 96 LEDs compared to my 224. My consumes 14W, while yours uses 48W according to the specs. Something's not right here. That said, those you use are still much brighter per LED than mine.
BillyIdle said:Yeah, I know. Not accusing you or anythng. Just saying there is something that is not correct. I think I've seen the formula they use, and the numbers are correctly calculated. So I think there is something about the way the LEDs are meassured for the specs that is not correct. Or something.
In the end it's the result we get from these LEDs that count, and not the numbers. Looking forward to the fatalli comp, to get my board properly tested. If it gives me fruits, I'm happy. Started some other fataliis recently, that just sprouted, which gives me the opportunity to compare under otherwise equal conditions.
Gary18 said:its the running cost thats why i started with leds so i didnt have to pay to run hundreds of watts so thats why i would not buy a 300 watt led light
BillyIdle said:I am quite sure that 300W of LEDs that only produce red and blue is far more intence than the same rating for 300W CFL. Large amounts of watts are wasted on reproducing light we don't need for our growing. That is what makes the LEDs so special. And that's the same reason I don't think you can compare lux/lumens measurements between CFL/HID/whatevere else with LEDs. It's apples and pears.
