What is the expected degradation of LumiGrow LED output?

Our lights are rated for 50,000 hours with no more than 10% degradation. Due to our advanced thermal management, you can expect our fixtures to last as long as 100,000 hours with minimal degradation.

What is the output of the Pro series fixtures in lumens vs. micromoles?

Lighting for horticultural purposes is measured in micromoles rather than lumens.  A lumen measures visible light for humans and is intended for general illumination, but it is ill-suited to measuring light perceived by plants. As we say around here, “Lumens are for humans.” In journals and trade publications, you’ll see light referred to in terms of micromoles per second per square meter (µmol/m²/sec).

LumiGrow fixtures are engineered to maximize output in the red and blue portions of PAR. These are the spectra of greatest use to plants. A spectroradiometer measuring µmol/m²/sec reveals that a 1000W HID light produces approximately 14% of its total output in the red PAR range and approximately 3% in the blue PAR range.  By contrast, a LumiGrow fixture produces 68% of its total output in the red region and 17% in the blue region.

Therefore, for every 100 µmol/m²/sec of light produced by a LumiGrow fixture, you receive 67.7 µmol/m²/sec of red and 17 µmol/m²/sec of blue PAR. Similarly, for every 100 µmol/m²/sec of light produced by a 1000W HID, you receive 14 µmol/m²/sec of red and 3 µmol/m²/sec of blue PAR.

smartPAR Software

How do I install smartPAR?

LumiGrow will first ship you your smartPAR modules to be installed into your LumiGrow fixtures.  Next, we will have a network integration specialist provision your network for you! Our network integration specialist provisions and tests the software on-site, then teaches you to use it!

Does smartPAR have any dynamic control, or is it all pre-programmed?

The smartPAR system allows you to setup your own custom light schedules to implement quickly and easily.  We are currently piloting a light sensor that would allow LumiGrow lights to adjust based on the light levels inside the greenhouse. This would allow the lights to turn off/dim as the sun’s intensity rises above a predetermined level.

I did not buy smartPAR with my fixtures originally, can I upgrade to smartPAR now?

Yes! Every fixture is smartPAR-compatible, meaning that at any time can be upgraded to the smartPAR Wireless Control System. Contact us to get SmartPAR.

Does smartPAR come with every fixture?

The smartPAR Wireless Control System is a product sold separately from LumiGrow fixtures. To enable smartPAR functionality, the fixture requires a module attachment and network implementation, allowing your fixtures to communicate with our smartPAR cloud-based software.
