Hi Sanjay,
I got a few question regarding the spectral anaysis
1.) Why there are no CCT data for 2000K bulb? Also in most of the major manufacture specification stated wavelength instead.
e.g.
http://www.venturelighting.com/On-Li...g/Specialt.pdf
MH 400W UBDX contain dominant wavelength of 462 nm. which fall in most of the same category as other 20000K from your data.
In a contary, a of plot Hamilton 400W 14000K SE 1 PFO 400W HQI N 140 have a CCT = 34583 which exceed manufacture 14000K. Therefore, what's the scientific relation between actual CCT and spectrum information. (I am thinking of Wien's Displacement Law) If you have more peak lampda, the overall temperature may increase. Please corect me.
2.) So 10K is the most efficient bulb because not only it produce better PPFD but also those PPFD occurs in a usefull range of spectrum (eg. 420+540-580) thus compensate around 15-20M of ocean water. Correct?
Thanks
