I recently bought a panel on AliExpress for much cheaper than most of the branded one. There's not really reason for them to lie about the wavelength of the LEDs, so build quality is really the only risk factor.
- pseudosaid 2y agojust lie about the led itself as that is the costly component. Who is gonna measure wavelengths and hold them accountable? its a no brainer move to scam the most expensive component that also is hard to verify
- goda90 2y agoAre LED's particularly costly though? Does one wavelength of red LED differ significantly in price from another wavelength of red LED? And does that even matter that much? It seems like higher wavelength has deeper penetration, but how deep you want depends on use case.
- literalAardvark 2y agoYou would get deeper penetration from very high power leds driven intermittently though. So there may be a very different grade of led in the pricy stuff.
