I don't like CLW because they play the "proprietary spectrum" game. Logically, that can only mean they are appealing to "secret sauce." That you're getting something so advantageous it must be kept secret. CLW will say it's to prevent competitors from discovering the "secret." But, any competitor who wants to know the secret can acquire a light and figure it out. As soon as a light leaves the door, it's no longer "secret." You can even buy a DIY spectrometer (PublicLabs) for $35 to discern the ratio of red/blue, etc. Therefore, logically speaking, the only purpose to play up the "proprietary blend" is to promote buying on less-than-objective criteria.I've seen and read almost entirely good things and results from them.
That coincides with CLW's use of "adjusted PAR" values in their literature. They put the disclaimer in a footnote which few will take the time to consider -- instead of displaying actual PAR values.
For the money I think you can do better (and promote transparency).
