Philips GreenPower toplighting LED solution claims to bring more light for the same amount of energy, optimised light spectrum and a "significant" reduction in radiated heat.
Three large cut rose producers from Belgium and The Netherlands have now installed GreenPower toplighting and are using Philips’ light recipes to obtain significant improvements.
Philips GreenPower LED toplighting, introduced in July 2015, enables higher yields, greater quality and lower costs than other available solutions. LED toplighting claims to be 50 per cent more efficient in converting electricity to light (up to 2.7 μmol/Joule) than high pressure sodium (HPS) systems that have been prevalent in the market.
Growers can also reduce operational costs, with Philips claiming up to 42 per cent energy savings compared to HPS lighting, lower installation costs and maintenance costs.
Philips Horticulture LED Solutions general manager Udo van Slooten said: "There is a growing amount of scientific evidence showing the benefits of LED toplighting for the floriculture business. This technology is particularly interesting for rose growers because their crops require some of the highest levels of light in the floriculture industry. It’s not unusual for roses to require 4,000 to 5,000 light hours in a year. Growers can use LED toplighting to save energy, steer their climate better, create more lighting hours in spring, summer and autumn and get more growth and/or quality."
. Cut rose growers using Philips GreenPower toplighting include:
- Family run commercial rose grower Wimceco BVBA, which is using Philips GreenPower LED toplighting in its 17,000 square metre greenhouse in Boechout, Belgium.
- Scheers Rose Nursery in Kontich, Belgium is installing Philips GreenPower LED toplighting over about 15,000 square metres to enable longer growing hours due to greater control of temperature and CO2 levels thanks to the new LED toplighting radiating less heat.
- 115-year old Porta Nova, the biggest grower of Red Naomi roses in the world, is trialing Philips new LED toplighting module over 1,300 square meters in Waddinxveen, The Netherlands to reduce energy costs and emissions in anticipation of stricter emission regulations.
Scheers Nursery owner Wim Scheers said: "With LED toplighting, I can switch on my LED separately so less heat is produced, meaning we don’t have to vent off excess heat and can leave the windows closed longer. Keeping air inside reduces my costs, and also helps me maintain a better balance because I’m not constantly having to add extra CO2 to compensate for what’s going out the window. I will be able to light my plants for more hours without raising the crop temperature and retain more CO2 which will increase my crop growth and thereby increase my quality or yields."
Philips will display its GreenPower LED toplighting solution for cut roses and other floriculture at the International Floricultural Trade Fair (IFTF) in Vijfhuizen, The Netherlands, 4-6 November 2015.
