Our Mission

Due to the relatively straightforward care required for plants and freshwater species, many brands in the market offer low-cost products using existing light fixtures combined with consumer-grade LED chips. However, just because a plant can survive doesn’t necessarily mean it’s thriving. Feedback from professional growers indicates that the available lighting spectra in the market are notably lacking.

Precisely because plants are easy to keep alive, there is a lack of scientific knowledge among plant growers regarding the selection of lighting fixtures. As of today, the development of consumer-grade LED chips primarily focuses on visible light intensity (PPFD) and cost, resulting in spectra that fall far short of replicating natural sunlight. Numerous botanists and research institutions have also observed that while plants can survive and grow under artificial indoor lighting, the quality of growth is significantly inferior compared to sunlight.

Growth quality encompasses aspects such as leaf expansion, leaf thickness, stem width, flowering, and fruiting cycles.

Therefore, in 2021, we began developing the next generation of truly simulated sunlight spectra, which not only enrich the visible light spectrum but also include various UV and infrared wavelengths found in natural sunlight on Earth’s surface, providing the most authentic natural light illumination.


With our lighting and optical laboratories, we utilize the latest technology to customize the world’s first simulated sunlight bulb on the market, achieving an unprecedented 96% accuracy. This bulb not only provides a continuous spectrum but also includes UVB, UVA, the entire visible spectrum, and near-infrared wavelengths (310nm to 740nm).

Furthermore, by enriching all visible light wavelengths, our spectrum achieves an astounding color rendering index (CRI) of 99+. This is close to, if not equal to, the color rendering index under natural sunlight.

Advantages of invisible light

With rapid technological advancements over the past few decades, an increasing amount of botanical research has shown that non-visible light spectra such as UVB, UVA, and infrared have positive effects on plant development.

For example, plants use special pigments in three light-sensitive Photoreceptors, namely Phototropin (phot), Cryptochrome (cry), and Phytochrome (phy), to gather information from the incident light. These photoreceptors are highly sensitive to different wavelengths of light.

Recent studies have shown that these special pigments in the light photoreceptors respond not only to visible light but also to non-visible light such as UVA, 660 nm photo-red , and infrared, resulting in positive growth reactions.

Myth of PPFD

Individual brands typically market based on PPFD values (photosynthetic photon flux density), where higher PPFD values correspond to better plant growth and growth quality.

PPFD measurement originated decades ago when the understanding of botany and light measurement in the consumer horticulture sector was limited. PPFD provided a relatively simple and understandable reference value for the consumer horticulture industry and non-professional consumers. However, PPFD is only applicable as a reference value derived from visible light measurements for photosynthesis.

Moreover, most plants require PPFD values between 250-350 μmol/m²/s, yet some brands continue to promote higher wattage, pushing PPFD values above 1000 μmol/m²/s. Unless used in large-scale commercial cultivation, these high PPFD values offer little benefit to the average consumer or improvement in planting quality.

Light Quality

Photosyn has introduced a new concept and research direction called “Light Quality.”

“Light quality” refers to the quality of light rather than its intensity (PPFD). Leveraging its proprietary technology, Photosyn simulates a spectrum that is very similar to natural sunlight, achieving a 96% resemblance. This allows us to produce the invisible light necessary for plant growth, which is imperceptible to the human eye. Therefore, under the same power, the light emitted by Photosyn appears weaker to the human eye compared to traditional consumer lighting fixtures. However, its ultra-high-quality spectrum not only enriches all visible light but also significantly improves color rendering to match natural sunlight levels, while also supplementing the invisible light between 310nm and 740nm to enhance plant growth quality.
