This is called photosynthesis, which means "making through light".

Based on email I get, forums I regularly read, & YouTube videos (for DIY LED Aquarium Lights), many seem to make this very INCORRECT assumption about emitters, drivers, PWM, wasted heat energy, etc.
This has resulted in a plethora LED lights flooding the market that are non reef capable, marginally reef/planted capable or very reef/planted capable, BUT often requiring 3-4 times the input wattage for EQUAL efficient PAR!
Basically one is back to the high energy input of a MH, but now in a LED.
It is NOT that many of these LEDs cannot keep photosynthetic life as we know these lights can and do quite well from practical experience, these are simply less efficient due to wasted heat energy, use of more of the less efficient, yellow, amber, green, or binned emitters; QUITE SIMPLE!

UV light (close to purple and blue)is very high energy and that's why we getsunburned.

Incandescent lamps tend to have a color temperature around 3200 K, but this is true only if they are operating with full voltage. When a lamp is dimmed below its full potential, its filament is not as hot, and it produces less light. The reduced temperature of the filament also reduces the color temperature downward. An incandescent light dimmed to 10% is considerably more red in color than one at 100%.


Cover the several lights with red, blue, green, and yellow films.

Photosynthesis requires the following resources; Carbon Dioxide, Water and light.

Light Filters are used and
light intensity stays the same The colors used in order of wavelength
blue being the smallest and red the largest so the order will go
white, blue, green, yellow, orange, red.


Why do plants photosynthesis better in white light, …

We did not count those disks into our data.
White light

The white light displays the effect colors have on the plant

In an ideal investigation, all the leaves should rise at the same time.

Plants in red, blue, green, white light and darkness???

PAR is the abbreviation for Photosynthetically Active Radiation which is the spectral range of solar light from 400 to 700 nanometers that is generally accepted as needed by plants & symbiotic zooanthellic algae for photosynthesis (Zooxanthellae are single-celled algae that live in the tissues of animals such as corals, clams, & anemones).
It is also noteworthy that while outside of the accepted PAR, a study using infrared (IR) LEDs of 880 nm & 935 nm on etiolated oat seedlings showed leaf emergence, so these parameters may someday need better defining (See at the end of article).

Purple is a color intermediate between blue and red

UVA to 550 nm contains the absorption bandwidth of chlorophylls a, c², and peridinin (the light-harvesting carotenoid, a pigment related to chlorophyll). The photons of light energy within these spectrums are more energetic and by themselves tend to provide more plant growth
620-720nm is the red absorption bandwidth of chlorophylls a and c².

Conclusion-

I can see from my results that white light produced the highest
photosynthetic rate at an average of 382 02 bubbles per min and green
the lowest at an average of 21.3 o2 bubbles per min.
