I would still call it an all-in-one spectrum because it has already enough blue for compact growth and good branching. (It needs only ~10PAR/w/m² blue wavelength to get compact growth)
I'm using 3000°k only as all in one since 2 years now and I really like this spectrum. The plants look like grown under natural sunlight. With colder spectrums 5000-6500°k the plants look almost like grown under blurples. Extremely short and branch growth is almost horizontal(70-80°). For height limited areas this may offer benefits but for "normal" heights I prefer longer internodes and branches at least at a 45-60° angle to the trunk.
But like ever there are exceptions.
For example for haze strains a 5000°k spectrum used as all-in-one can make sense and with the new purple/nearUVA + phosphor whites the sprectrums get better and better.
Nichia Optisolis 5000°k/CRI99 spectrum looks very good and achieves 61% efficiency(RFx00, RFx0f, based on purple 420nm pumps, no 480nm hole).
It sounds funny but purple wavelength are optimal for purple strains because they help to emphasize the colors, the taste and the aroma of the plants. In commercial horticulture purple and UVA are used for purple basil but also for medicinal herbs as it enhances flavonoids, antioxidants and other ingredients of medical use.
Combined with the extremely efficient Osram Square deep-reds (3.91μmol/j at 700mA) that would be the non-plus-ultra in my opinion.
Also the 3000°K/CRI98 looks very promissing for plant lighting( peak at 660nm, also RFx00, RFx0f ) and is even more efficient like 5000°k because the blue diodes used for the lower kelvins are a little more efficient like the purple ones in 5000°k diodes.
But like ever with the good stuff both diodes are not cheap. Cutter.com.au has already Optisolis diodes available and offer them for strips and boards and LED-tech.de has the Osram diodes. Grow strips with Osram Oslon and Square diodes are available and you can ask them for customizing because they are fully equipped from pick and place bot to an integrating sphere. Many customer designs are already available and they are also contractual partners of Nichia.
