AVAILABILITY : 0This lamp enhances photosynthesis and thus contributes to plants growth. The principle has been used by the NASA.Plants do not need all colors wavelength but only those in the red and blue ranges.Compared to fluorescent systems, this lamps is much more ecological. It produces less energy, less heat output. No waste of other, unneeded colors. And those bulbs are mercury-free.Hooks are supplied to suspend the light.Power Output: 50WInput Current: 0.35AInput Voltage/Frequency: 220V, 50Hz2000 LumensDimensions:- Diameter: 175mm- Height: 60mmExpected Lifespan: 20,000 hours
