Q:Besides Watts 32 and ADJ Spectrums how does this differ from the 30 W Full Spectrum Daylight ?
- What is Par on this ?
- When adjusted on Full Spectrum is Light intensity greater on one over the other?
To grow VEG to FULL MATURITY inside is one better?

A: This unit can easily be used in a 4'x4' grow tent. This one is pretty bright. I also have mine at 7' height and the tomato plants are growing out of control.
by|Feb 13, 2023
A: Thank you for your question, the amount of distance and time used all depends on the type of plant being grown. High Light Plants (such as tomatoes, peppers, perennials, etc) would benefit from 6” distance during the seeding stage, and a distance of 16”-30” during vegetative/flowering stage. Low Light Plants (such as basil, lettuce, etc) would benefit from 12” distance during seeding stage, and a distance of 24”-30”

Q:what is the PPFD for this fixture?
by|Mar 4, 2021
2 Answers
Answer This Question
A: It's a great little lamp. Let me know if this helps. see attached
by|Mar 6, 2021
A: Thank you for your question. PPFD is dependent on distance and area.
We can see from the carton that the unit emits 49 μmol/second of Photosynthetically Active Radiation. This value (49) is called PPF or Photosynthetic Photon Flux and this is the correct value to compare lighting products. PPFD is the density (D) which actually arrives at the plant and is variable.
