it's the spectrums that the light spits out
tri or quad doesn't tell anyone which spectrums are being used though
a tri band could be red/far red/blue, maybe red/blue/white, maybe red/blue/ir
so without knowing which bands the tri or quad are talking about, it's hard for anyone to say
this is the example of the triband with wavelengths http://cgi.ebay.com/90W-FULL-SPECTR...816?pt=LH_DefaultDomain_0&hash=item19b394b170
and this is the quad band one http://cgi.ebay.com/90-WATTS-LED-Qu...139?pt=LH_DefaultDomain_0&hash=item3f0540100b
im just wanting to grab the right one for the job out of the gate.
