LOL--I meant 23,000--2300 would not even do a foot of space. How do you know they are putting out 23,000 lumens if they are only pulling 200W? These lights are not capable of putting out over 100 lumens per watt, so if the wattage is not there, I am pretty sure that the lumens have gone down in proportion (or more).
The 6400 lights are better for vegging. You can use 2700K lights, but the plants will have more stretch and less budding sites than a plant vegged with 6400K.
I know. I'm mostly wondering, will 20.000 lm of 2700K do more for me than 8.000 lm of 6400K in addition to the 15.000 lm of 6400K I will be using no matter what.
I figure since its 2.5x the amount of lumens will that make up for it being the wrong spectrum? specially considering they will still get the 15.000 lm in the correct spectrum.
Coz they are rated 15.000 and 8.000 lm and I used a power meter to see that the one called 250W high power CFLwas pulling 134-138watts while I messured, so I figured the so called 125W would pull about 70W. They are power saving bulbs. And I trust the shop I use. It has a very good reputation, they only sell the best bulbs available. The 250W cost 83 bucks and the 125W cost 50 bucks.
