Look, if you're happy with these then I apologize for making you angry.
Having said that, I go into full skeptic mode when visiting free-for-all websites like AliXpress. I mean, really, the English is so poor
1.The color is full cover 380nm-840nm ,make up the 1w and 3w can not provide the special wavelength (as the Trace elements for human bodyhuman body, indispensible) .
2.Full spectrum led could use only ,don't use with othe grow lamp ,that slove the problem which is previously LED grow lights been unable to act as the sole light source for the indoor garden .
3.Suit for plant all stage ,so slove the trouble change different grow lamp at different plant stage .
4.The integrated light source ,more evenly ,more intense,more stronger than single light ssource .
that sometimes I'm guessing what they're saying, but the fact is they can say whatever they want. The Better Business Burea ain't monitoring AliXpress.
I'm not an LED expert. When I go to a website
like the one you linked I'm looking for clues like LED manufacturer, how many LED's, what's their maximum current and what are they actually being driven at, some benchmarks that might indicate efficacy; that sort of thing.
So maybe you can help me out.
Brand? The website says they're EpiLED. We know that there are lots of counterfeit Chinese Cree's and etc. so even if I bought one of these and it said EpiLED on the die I wouldn't really know. But you say above that they're Bridgelux. Which is it?
Binning? If these were highest bin, as you claim, I would think they would say so because that's a strong selling point. But I see no mention of binning whatsoever. And we loop back to the same questions of veracity - how would I know they're being truthful if they did?
How hard are they being driven? I can't tell. Can you? Since there's no exact description of the LED I can't look up the data sheet. The data sheet would give me some ideas about lm/W, spectrum, nominal vs. max current/voltage, etc.
I didn't say "I'm sure" these are sketchy LED's, I said "as far as we know" because I can't find anything on the website that gives me any confidence that they're not.
I don't know who Anchorman is. I'm not going to google him. Probably get Will Ferrell instead anyway. I doubt that one guy's word on this would dispel my skepticism.
If people can show great results I'll be happy for them. But the website is full of promises and virtually devoid of verifiable technical detail. That's a fact and that's why I'm skeptical.
