this is the shit. my plants will jsut crawl out from under any other light to reach for the CMH across the room. it's crazy town. 400 watt HPS magnetic balast tho, don't forget that and 400 is as high as they go I am pretty sure.
6500K color temp can be achieved by a wide variety of nm wavelengths combinations or spectrums...some of which would provide very little of what the plants wantthe way i see. if it's not producing a special light (which it's not) buy cheap. the only difference is whether the bulb works or not. a more expensive bulb may have a longer life or special things like lower temp, more spectrum like you listed. but 6500k spectrum is the same no matter how you look at it or what name you put on it.
you are mistaken friend...6500k is the COLOR temperature on the Kelvin scale of the light which comes from the temperature a piece of carbon is heated to to obtain that color...spectrum are measured in wavelengths of light... nano meters or the distance between peaks in the wavelength of light emission...for instance blue light is around 450 nm and red light is around 650 nm...that is the spectrum...it was an example. 6500k is the spectrum... you obviously don't know what you're talking about lol. no offense.
I do not suspect penetration would be an issue...sure its less lumens but that is because there is much less green and yellow in the spectrum and more blue and red...lumens focus on the light humans perveicve best...green and yellow opposite of what plannts use...but the energy factor is actually higher then the lumen rating indicates because of the spectrum...and I find blue light and uvb to be greatly beneficial....but NO cmh does NOT provide useful amounts of uvb...NO hid bulbs do other than a couple of mh available here:I'm not a big believer in the value of blue during veg or flower, but clearly the red is handsome on the CMH.
So one of the links is to a CMH with more than 400 Watts? 830 watts, is that right?
Is the penetration an issue, relative to a 1000W HPS? It would seem the 1000w would have the advantage in canopy penetration.
my point being the manufactures can obtain kelvin readings of the same measure using manipulation of the green and yellow (500-600nm) and achieve a higher or lower kelvin while not actually producing more blue wavelengths...so do you still think I know not what I speak?like you said the 6500k is the color temperature. and we know that colors are seen because they are at different wave lengths. so a 6500k bulb has relatively the same wave length as any other because the color temperature is the same. so say for instance it's violet. and violet is 400 nm. all violet will be around 400nm. i was initially wrong with the 6500k is the spectrum comment, but my original comment is still valid. unless there is something im not seeing.
