Support during the growth phase with the high pressure sodium lamp from Lumatek, in the smallest version available - 400W.
Lumatek too makes use of the blue light colour spectrum for its metal halide growth-spectrum grow lights. With a colour temperature of 4328K, the 400W version can give off an astonishing 44,000 lumens. The PAR value (photosynthetically active radiation) indicates the spectral range of sunlight used by living organisms to perform photosynthesis. Tables and diagrams provide better explanations for this.
Lumatek's metal halide lamp are the first choice for all hobby gardeners who prefer a lamp with a long lifetime (10,000 hours!).
Note: To operate this lamp, a ballast with suitable performance values (400W) is required, as well as an E40 bulb holder.
Tip: Never touch the glass parts of lamps with bare hands! The skin's oils can reduce the lifetime and luminosity of the lamp.
