I disagree a little - but maybe your bill is calculated differently.the new led is pretty expensive buy... last longer than bulbs systems.. but do not save electricity
i replaced 630 watt of cmh with 945 watts of leds.. no saving cost more and buds are not as dense..
i want denser bud with more weight!
Left bank is one 1000w DE, digital ballast. >3000PFD at 80cm. On the right two Mars Hydro FCE4800 (only on 50% and 75%) the HPS is 6.5A of the 9.2 shown.
Upstairs on another box I have 3x FC6500s @ 730w each 100% for 2190w. Draws ~6A total.
Less than one HPS. I have a no name brand 320w LED draws about 3A on max - nearly what the two 480w take on max.
I’m pretty sure someone more electrically minded than me will confirm that the additional Amps cost more money at the meter.
One thing we can agree on is the HPS and CMH (in veg) do seem to produce special nugs! These are 3 weeks in flower.
