Driving the unit is an Omega 600w Digital Ballast, converting old HPS technology into top of the range LED light with the boost setting on the ballast. This means if you've got old Omega 600w Digital Ballasts, you can upgrade the technology to LEDs for a fraction of the cost, or purchase a fixture with a ballast. A ridiculously low-priced unit — the most cost-effective LED in the entire industry Regulated by a digital HPS ballast — use your own digital ballast and save even more money! One of the lightest bar LED grow lights yet released — weighs next to nothing Supplied mostly pre-assembled — can be up-and-running in five minutes Folds in half so it can still fit through loft hatches, etc. Produces a very respectable 2.7 µmol per watt of electricity (1950 µmol/s ppf) High efficiency levels mean more light and less excess heat Produces a footprint that's almost perfectly even Optimised for a space of 1.2 - 1.5 square metres Full spectrum output with a LOT of red and plenty of blue Comes with a huge 50,000 hour lifespan — lasts for up to a decade on a 12/12 cycle!
