Companies with smallest binning parameters in regards to wavelength/intensity

Hi,
My name is Mac, I'm brand new to the forum but have been doing quite a lot of research on LEDs and my questions are often answered by past posts on this forum. I'm building a DIY LED panel in order to have tight control over the spectrum/size/shape/intensity of the final product. In an effort to have the light panel turn out as close to my designs as possible, strict quality control is a must. The light will be used for moss production (the species I've chosen need about as much light as a typical plant with 95% saturation points between 1,000umol/m2/s and about 2,000umol/m2/s).

If anyone knows of specific companies which have tight binning parameters in regards to first, wavelength (preferably 5nm for the entire spectrum of bulbs,10nm at most, and with using peak NOT dominant wavelengths) and a close second, intensity (5% or under would be nice) it would help along my process greatly!

Thanks in advance for any help!

i cant see why they wouldnt be equally as beneficial for your application, but not familiar with the species

common sentiment is the less active wavelengths outside of chlorophyll peaks are also important for development.

in any case they are very efficient and produce consistently great results on our side of the fence

Hi Mac
it might be possible to get tightly binned royal blue and red LEDs but bins in other colors are more loose and there are even some gaps monos don't cover. Combination of manufacturers can probably get you as close as possible. Dominant wvl-binned LEDs shouldn't be a problem as you can find peak vwl from a SPD chart.
You're also looking at a quite high number of LEDs if you want to be able to control the spectrum while reaching 2000 µmol/m^2/s. How big a fixture are we talking? Is there power efficiency of any concern?

COBs would be an efficient and cheap way to get a lot of quality light but it won't allow you to tigthly control the spectrum.
