I did a side by side using the Hydroponics Hut X5-500 vs the Amare SE-450.
Bought the HH mktd as a pro-series light & I was impressed w/ the ratios shown on the spectral graph based on what I learned. Burple but still full spectrum having just enough in the greens, so I thought.
Well, needless to say, the HH got absolutely spanked by the Amare. Would've been laughable if I didn't waste $800 on the light & lost another $2000 in yield differance.
This made me lose all faith in Burple lighting. Sure, there's much better burples out there but they're being replaced by white or enhanced white by now.
For example: BML's Grow-Max spectrum, replaced by FluenceBio's new enhanced white spectrum, PhysioSpec. The owners openly admitted to the Grow-Max Burple spectrum being wrong & the cause of bleaching.
Full spectrum white light or enhanced white will smash on Burple. Can't find any evidence to say differant.
It's good to see side by sides but the grower must inteand or expect to loss yields as I did.
