Hi Skiball,
My first blurple was a, “Kind”, flower bar and even though I had all my spectrums with white light from 6500K to 2700K and with blurple noticed immediately more bushy growth compared to just white light.
Many large scale growers that use white light still add a row or two of blurples.
For DIY here in U.S. I would go with, “Timber”, or “Rapid Led”.
The latest in technology now though are QB (quantum boards).
My next light will likely be something like this one:
I would avoid China myself but maybe better service from Europe? If one has a problem with a China light then very little real customer service coming out of China. Many horror stories about fires, false claims of wattage and coverage, and even reports of counterfeit parts or substitution of advertised parts for China generic parts.
Everyone I know that has bought a China Led has had part (or all) go out in less than a year. My biggest concern would be fires though.
Many Amazon horror stories on China blurples just set search for lowest ratings on popular China blurples and start reading. Funny how many of the positive reviews on China blurples are in the same broken English (wonder why?).
