Spectrums Tailored for Livestock

5000K|5000K + 620nm|Full Spectrum

We don’t just provide light; we provide the right light. The T21 Series offers scientifically optimized spectra to match the visual physiology of your herd:

5000K (Daylight): Helps regulate natural circadian rhythms, improving feed intake and keeping animals calm.
5000K + 620nm (Red Enhanced): The addition of red wavelengths promotes blood circulation, reduces stress levels, and supports overall herd health.
Full Spectrum: Closely mimics natural sunlight, elevating animal welfare and ensuring a stress-free environment for consistent productivity.

120.5° Ultra-wide Beam

Maximum Coverage. Minimum Cost.

Featuring an ultra-wide 120.5° beam angle, the T21 eliminates dark spots and harsh shadows that can startle animals.

For farm operators, this broad light distribution means you can achieve uniform illumination across your barn using fewer fixtures—significantly lowering both your initial installation costs and long-term energy consumption.

Quick & Easy Installation

Farm labor is expensive, so we made the T21 fast to put up.

FAQ about T21 series

What makes the T21 better than standard waterproof LEDs?

Standard waterproof (IP67) lights keep water out but fail to block ammonia and hydrogen sulfide gases, which quickly destroy standard silicone LED chips. The T21 uses FTC Ceramic Technology to seal the chips at a microscopic level, making them truly immune to corrosive agricultural gases.

Should I choose the Transparent or Frosted cover?

Transparent covers are ideal for high-bay installations where maximum lumen output is required. Frosted covers are highly recommended for lower ceilings (like horse stables or milking parlors) as they heavily reduce glare and protect the animals’ eyes.

What is the warranty on the T21 Series?

We stand behind our engineering with a comprehensive 8-Year Warranty, ensuring your investment is completely protected.
