How much does it cost to operate my indoor garden lighting system?
Below is a table based on operating the light only 12 hours a day at 8 cents per kilowatt hour. Check your electric bill for your electric rate. Wattage Estimated monthly cost 150 $4.97 250 $8.28 400 $13.25 1000 $33.12 To calculate your energy cost you will need to know 3 things: A: Your cost of energy (usually identified as "KWH" charge on your electric bill) B: The total watts of your lighting system C: The total operating hours ("ON" time) of your lighting system per month. Formula = A * B/1000 * C = Total Energy Cost per month So for the above table: A = $.08 , B = 460, C = 360 hours (12 per day * 30 days) = Total charge of $13.25![]()
lol its great info but im lookin for like a no or yesthats just melted my head...![]()
mange, don't confuse the marketing hype, 400 watts == 400 watts. A 23w CFL uses 23 watts, and the equivalent rating is only compared to incandescent. No one here successfully grows with incandescent, so it's not even worth mentioning.one step further...a 23watt cfl is equivelant to a 65 watt bulb. same amount of lumens, less wattage. a 65 watt cfl is equivelant to 100 watt incondescent bulb. flourescents use less wattage...they are based on equivelant. light produced"lumens"vs power consumed"wattage"
I agree that the equivalent wattage stuff is useless in this context. However, what I dont agree with is that the higher wattage HPS are more efficient comment. At a certain point the bulb is so big and so hot that you cannot get it close enough to the plants for maximum efficiency.mange, don't confuse the marketing hype, 400 watts == 400 watts.

A 400w HPS will put out about 50% more light then an array of 23w CFL's for the same wattage. Higher wattage CFL's are also less efficient, while higher wattage HPS are more efficient.
What is there to disagree with? It's a simple fact, light output to watts consumed ratio:However, what I dont agree with is that the higher wattage HPS are more efficient comment.
Acutally, 2-600w HPS lights are more efficient than 1-1000 just because you have greater light distribution even though you're 200 watts over the thousand watt400w HPS lamps are less efficient then 600w or 1000w HPS lamps..
