That would be incorrect as they did have several white diodes also.
Hans panel V1 had no white leds in 2011/2012 ......450, 620, 660nm, it was my first led grow coming from a long hid hiatus. It's on this site somewhere ; ) he added 2-4 cree 4000k xpg/xbd? On V2
Wasnt those HansPanels the simple high 450 & 660 peaks. Thats it? And it still did so well ?
was not many other prebuilt options using decent parts for a small closet grower? Apache, Plant photonics came a little later, crazy prices, hand built. A51 hypetrain after, DIY guys really paved the way in consumer education and future wants from the led growers.
Hans did "well" due to its system efficiency (remote driver, quality mcpcb, some top bin) for that time & segment = subjectively speaking vs china mono panel dump(ufos everywhere) on the led world. You weren't flowering trees, training/scrog/sog was a almost a must....
Lots of watt boosting crappy diodes that were originally meant for traffic signals and other nondemanding shit. Stuck some active fans blowing on untested/thin PCB's and called it a day, premature failure rates were extremely high ( for an electronic product) back then.
Good memories
