1. Do multi-bar grow lights provide more even light distribution than LED panels?
Yes! Multi-bar LED grow lights reduce the effects of shadow, providing better light distribution. The spacing between each light bar gives you more consistent light.
2. Is a power inverter required, or may this be connected directly to a 110v USA plug?
The light can work with AC100-240V, therefore a power inverter is not necessary. It satisfies all requirements to be used in the US.
3. Does this light provide UV light?
No, this light does not have UV light added. We can add UV diodes if needed.
4. Can I run this light without CO2?
Yes, you can run it without CO2 supplementation. While adding CO2 to your grow room can enhance plant growth, it is not a requirement for using LED grow lights.
5. How many watts does this light use when running at 100%?
The actual watt will be rated power±5%. For this light, the watt will be 320W±5%.
6. What size of grow tent does this grow light fit in?
This 320W multi-bar grow light is ideally suited for 4×4 foot (1.2 x 1.2 meter) or 3×3 foot (0.9 x 0.9 meter) grow tents.
