Yup, its official, Im addicted to growing... hopefully my reef tank doesn't get neglected!
Ok guys, there has been STRIDES in LED lighting over the years. While window shopping for an HPS (would 400w hps be sufficient for a 6x6x5ish room, 6 plants?) I stumbled across this little beauty.
Go to ebay, search item number 270491627657
Specs:
Diameter: 10.5 Inches
Depth: 2.5 Inches
Number of LED's: 90
Total Wattage: 90
Lifecycle: 50,000hrs
UV LED: 425nm
Red LED: 660nm
Uses only 90 watts?!
But wait!
"In our 2009 LED Growlight Showdown, our winner (Lighthouse Hydro) employed a unique LED. After our analysis, we concluded that the reason for the win was the use of a mixture of 630nm UV/Blue LEDs rather than the traditional blue 660nm LEDs used in all other LED systems tested. This is confirmed from the spectrum usage graphs above.
So in usable lumens we have the 3900 lumen 90w LED from Lighthouse Hydro vs the 400w 6800 lumens of a Sun Agro bulb.
LED= 43 usable lumens / watt HID= 17 usable lumens / watt
Yes, the LED is superior but based on lumens/watt alone a 90w total output is not equivalent to a 400w HID light.
On Lumen output alone, a 90w LED does not match the 400 HID light system. In usable lumens alone the conversion is more like 90w LED = 230w HID (HPS/MH)"
So, get two, your going to spend about $300 and youll match the lumens
BUUuuuuut, your only burning 180w total.
What do you guys think?
