The Growers Choice + TSL ROI-E720 LED grow light is designed for commercial growing operations of high value crops, but can just as easily be used in smaller operations and grow tents. The ROI-E720 LED grow light is the latest offering from Growers Choice taking the place of the extremely popular ROI-E680. The 720 increases the wattage from 680 to 720 and includes newer improvements to LED technology. The ROI can also be used in the BOOST mode to increase the PPF of 1870 umol/s to 2050 umol/s (approximately 10%).

DLC (Design Lights Consortium) Listed Light and Qualified Fixtures
DLC stands for Design Lights Consortium, a group that certifies light efficiency to be used in energy rebates around the world. The DLC independently certifies the quality and performance of lights, most notably LED grow lights used in commercial growing operations. DLC is used to make sure that lights adhere to the specifications that are advertised. If we say a grow light operates at 2.8 umol/J efficiency and 95 CRI (color rendering index), who is to say we are not lying? Same for Power factor, Kevlin, THD and more. Unfortunately a great number of companies mislead customers on efficacy data. This problem is why the DLC was started and why you should be paying attention, even if you are not eligible for energy rebates from your local energy company.
An example of a use case for getting a DLC qualified fixture: If you have an existing or new growing operation considering a purchase of 100 HPS 1000w grow light fixtures, you can reach out to your local energy company telling them you're considering buying LEDs instead of continuing to use or replacing your 1000w HPS lights. Most of the time, energy companies will give you 20-60% of your more efficient fixture cost in teh form of a rebate against your future energy bill. For example, if you were getting LED fixtures that cost $1,000 each and the energy company gave you a 60% rebate, they would effectively give you $600 back in credits for each fixture you buy bringing your net cost of the fixture down to $400. For the majority of energy companies, they require DLC qualified fixtures in order to be eligible for a rebate.
