Yes, that's how LEDs are manufactured, at least the LED emitters used in reef lighting (UV maybe no so much). Without primary lenses, the emitter is exposed to the salt air, dust, etc. Primary lenses produce a net gain in light and make LEDs more efficient. None of the emitters used in reef lighting are purpose built for the companies who use them. If they were, there would be no reason to use secondary lenses, because the primaries would be manufactured to meet the needs of the Ecotech's lights.
Secondary lenses refocus the light from the diode and primary lens into a new beam. This is not a new concept.
After watching Jake's "detailed" assessment, it's clear that he knows little about LED emitters. He's overly-impressed at the size of the emitters, and seems to think the size and appearance of emitters is somehow meaningful when it comes to function. It was good for a laugh, though.
