Comments:  “I have several of our manufacturers with a great line of fixtures for greenhouse applications. They are making headway and I see new case studies often; however, as the article states, adoption is slow due to several factors; The higher cost of the fixtures despite many advantages is one of them. The difference in the commercial market is prices have dropped, quality has really improved, and with rebates, it’s a no brainer. LED has become the standard in new construction and upgrades are all happening every day.  When will this change for greenhouses? I don’t believe that long.  Funny thing about lighting is it takes some urging to get folks to see the many benefits, but when they do finally get, it can’t happen fast enough; Reach about your projects, please.” Here is the article and link…

Almost all of the most recent research into greenhouse lighting has focused on light-emitting diode (LED) technology. There’s a good reason for this, as the long-term energy savings that can come from the use of LEDs — and the rebates and local grant programs that growers can take advantage of — make it an appealing option.

So why are only around 2% of greenhouse ornamental growers (according to Erico Mattos, Executive Director of the GLASE consortium) using LED systems? If you talk to industry suppliers, there is a host of reasons.

“Lighting, on average, is 50% of a commercial operation’s energy costs, but the economic feasibility of switching to LEDs is not always the most important thing on growers’ minds,” says Taylor Schaberg, Managing Director of ActiveGrow. “Most growers are hesitant to change to LEDs due to their prohibitively high cost, even if they can get that money back within one to two years from energy savings and potential rebate opportunities.

In some cases, Schaberg says, growers have dialed in their operations to work successfully with HPS lighting systems, so using all new LEDs is off-putting.

“As technology changes and LED prices drop, some growers feel they can wait until these systems become more affordable up front to jump in,” Schaberg says.
