Ursa LED’s flagship and patented Helios fixture is the ultimate in grow light technology!

Both component and fixture level optimization allows the Helios GT to produce intense PPFD output. Their patented, high-powered, single source LEDs allows for extreme penetration through the canopy.

By doing so, the plant receives an abundant amount of light in the lower parts of the canopy, allowing for increased yields and production.

Delivering a broadband red spectrum of 80 nanometers (620nm-700nm), combined with a 450nm royal blue, the Helios GT series is optimized with one condition in mindmaximum performance in a grow tent setting or grow room.

The high dispersion rate from the wide angle optical lens technology allows maximum PPFD output to reach lower levels of the canopy through reflection inside the grow tent.

With penetration reaching deep into the canopy, no light is wasted with the added advantage of higher absorption rate and growth rate from lower branches.



  • 1200 PPFD at 12” From Canopy (320W fixture)
  • Broadband Red Spectrum of 80 nanometers (compared with 25nm industry standard)
  • Patented High Power Single Source LEDs from Flip Chip Opto
  • State-of-the-Art Phosphor Conversion Removes the Need for Inefficient Red LED Chips
  • Including UV-A and Far Red at the ends of the spectrum
  • Customizable Spectrum: White Light (3000K, 4000K, 5000K)
