Counterbalancing Cold Color Temperature (K) in LED lights

Yes, where in that range the photons are makes a difference, but unless they're really skewed to one end or the other of that range, it's unlikely to be an issue.

Two things to keep in mind: in fluorescent lamps and LEDs, the color temperature does not represent the true spectrum, but represents the appearance of that spectrum to the human eye. Secondly, the human eye is most sensitive to the green wavelengths, so that's where white LED lamps are most intense, giving us a false sense of brightness.

I guess that the bottom line is that white LEDs will all work fine for our plants. The "warmer" colors tend to have more far red, which is good for blooming, but it's notcritical.

Thank you for your help! I understand what you are stating regarding how in LED and fluorescent lamps, the indicated color temperature isn't indicative of the true spectrum. That being said, I did find another fixture that is very similar to the one I have. It may be an improvement. It states the wavelengths of red, blue and green lights. Now, I know the green lights aren't helpful since they aren't at the tail end of the 400-700nm spectrum. My existing lamp only has blue lights. Of course, I want something that helps with blooms too.

Here's the product:

Here's the excerpt that I found relevant: "Fixture is pre-installed with 10000K, Actinic 460nm, Red 620nm, and Green 520nm spectrum LEDs. "

What initially drew me away from this one is the 10000K white lights. I now know that this isn't relevant. Can we trust the wavelength information with LEDs?

This product has slightly less lumens. However, I suspect it may be a better product. What are your thoughts on this Ray? Is it worth me returning my current lamp for the above one?

Thanks as always!
