I can't grow right now. I don't think I'll be able grow as soon as I thought I would be able to, when I came back to the cultivation community a month and a half ago, due to my investor backing out for unrelated reasons, but that passionate spark has been revitalized. I give you a fixture designed to potentially outperform a Solis Tek 1000 Watt DE HPS based off of the numbers from Vero 29 datasheets and advertised figures from Solis Tek.
This could be used in a 4'x4' frame or 3'x3', your choice. Real-life testing would be required to determine the difference. This has been designed as a full cycle light, although when I build out my operation I'm going to have different LED fixtures dedicated to veg and flower respectively. Its (9x) Vero 29 SE Gen 7s 3000K running @ 38.7 volts x 2.1 amperage producing 81.27 watts per diode or 731.43 watts per fixture. This light would have an initial usable light output of 1647.018 PPF or 1105.38 PPFD over a 4'x4' space. That's compared to the advertised >2,000 PPF/ >1342.28 PPFD of a 1000 watt Solis Tek DE HPS Bulb. A member of the farm posted that light degradation of this HPS bulb reached a 28% light output deficit by month 3 of running the bulb 12 hours on 12 hours off. Meaning at month 3, typically within the range of a standard growing cycle, light output of the 1000w DE HPS bulb would be 13.41% lower than the initial output of my proposed LED fixture, which would have minimal degradation. Further testing is required to determine the exact figures on how much total usable light is received by the plants throughout the entire cycle, comparing both systems.
We'd need a somewhat 'long-term' study to determine when the best time to replace COB LED diodes would be, but its currently understood that the diodes of LED have roughly 5x the life of an HPS bulb.
Savings:
Assuming your cycle is 3 months; 4 week veg, 10 week flower. Then, we can assume the per year bulb replacement costs would total $3,680 for 10 lights over the course of a year. With 10k HPS costing $5,256.00/year and LED costing $3,844.40/year to run (electricity cost wise @ 12 cents/kWh) , you'd save $1, 412/year running 7314.3 watts of LED vs. 10,000 watts of HPS.
This LED fixture would cost roughly $750 to build, consisting of the highest quality components you can source, including multi-turn dimming capabilities, compared to $330 for a 1,000 watt DE setup where the price is alleged by a member who's proved success with such bulbs through documentation on another community. Is it the highest quality DE build you can put together? Probably not, but the LED is. Regardless, LED can accept such a handicap with ease.
@ 1 Year
$1411.60 savings from lesser power draw using LED.
$3,680 savings from not needing to replace the bulbs 4 times/year.
Total yearly savings using LED = $5,091.60
Initial Fixture Cost:
(10x) $731.43 LED fixtures = $7,314.3
(10x) $330.00 HPS DE fixtures = $3,300
Initial investment surplus with LED fixtures = $4014.30
Profit after one year using LED, assuming yield is neither increased nor decreased = $1,050.30
So, theoretically, after 1 year, assuming yield is exactly the same as if using 1,000 watt HPS DE, LED would save you $1,050.30. This is disregarding potentially increased yield, higher quality bud, etc.
