Yes, it can. And here’s the maximum daisy chain numbers:
110 V< = 30 pcs
120 V< = 32 pcs

[av_toggle title='Why there’s only 2 years warranty while other lighting have 3 - 5 years?' tags='' custom_id='' av_uid='av-mmen0rzt' sc_version='1.0']
A 2-year warranty is the industry standard for professional UV grow lights. UV chips (especially UVA 395nm) are more sensitive to temperature and humidity, and degrade faster than regular white LEDs. In the high-temperature, high-humidity growing environment, UV lights operate under harsher conditions, so their warranty period is shorter than that of full-spectrum main lights. Warranty period ≠ product lifespan. The LED lifespan of the HydroGrow UVR30 can reach 50,000 hours, far exceeding the 2-year warranty. The warranty mainly covers manufacturing defects, not normal light decay. With proper use, the product can work stably for many years after the warranty expires.What's more, UV LED chip manufacturer (Seoul Semiconductor) only provide 2 years warranty.

[av_toggle title='Why the waterproof rate only IP53 while others have IP65?' tags='' custom_id='' av_uid='av-mmenjfs9' sc_version='1.0']
There is no PC housing cover on the LED bead side because UV light accelerates the aging of PC material, making it brittle over time. This is why the fixture is designed without a PC cover, and the waterproof rate is IP53.

Our UV lights use the UVA 395nm wavelength, which is safer than UVC (which can directly damage DNA and RNA, has strong immediate harm to skin and eyes, and may cause severe burns and permanent damage).
Although UVA 395nm does not cause such intense immediate injury as UVC, it is still a major cause of skin aging, wrinkles and increased skin cancer risk, and can also cause chronic damage to the eyes.
It is recommended that people not stay in the room when using the UV light, or use it inside a sealed grow tent. Please also wear safety goggles when tending to plants.
