So, say if there was a 600W LED array that could replace your 1000W HPS in terms of yield. (Quality will probably be higher with LEDs)
What would you pay for one?
Generally a 1000W digital with reflector and a cheapo bulb will run around $500-600, and use about 1060W due the the ballast losses.
Take into account 2 cheapo bulb changes a year means about $100 a year in bulbs. Power use for the 1000W over a year at 12 hours a day @ $0.10 / kWh would be $465, so about $565 minimum to run a 1000W HPS. Up to about $800 a year with more expensive bulbs and power @ $0.13 / kWh.
A 600W LED array would cost $263 per year @ $0.10 / kWh and $341 @ $0.13 / kWh.
This makes for a savings of $302 - $459 per year in the LED array alone, not to mention all the HVAC savings.
If the LED array was built properly and lasted for 50,000 hours, that means 11.5 years of use @ 12hours per day. This would mean $3474 - $5278 in savings over the lifetime of the LED array (minus the difference in cost between the $600 HPS setup and the LED array). Multiply that by 10, 20, 30, or 200 lights, and you've got some serious savings.
So, what would you pay for this device if it existed?
