Target LED lamp lumens

Neither. It's a general term as it is used for that lamp. Lumen specifies how bright that lamp will appear to the human eye. Peak sensitivity occurs in the green yellowish portion of the spectrum at 555 nanometers wavelength to be specific. A lamp outputting in that region will look bright to us but not plants.
For lumen/PAR/ lighting intensity to have any meaning, a light source would have to state how many lumens it emits at all PAR wavelengths. It's usually not done that way. Units known as Micromoles are used. PAR and lumen is well defined within this forum and the web. Just do a search. Neither term is too complicated to grasp.

That lamp must be constructed with very low power leds, because 200 lumens is less light than 1 typical 3 watt led will produce all by itself. You'll need much more light than that, if you want to grow anything other than low light moss.

Unless a significantly fast shutter speed was used, I believe this will be an excellent source of light for low light plants. My understanding is that the yellow part of the spectrum (as seen on the pictures) are not ideal for the highly demanding plants, such as dwarf baby tears and non-greens (rotala colorata, ludwigias, red cabomba, etc).

no photo tricks. Just my android phone. Thanks for the input, I hope you're right.
