GLT8I20 is a 20W LED grow light, specially designed for replacement of traditional fluorescent grow light tube in horticulture applications, such as tissue culture.

Less Power & More Growth



FST is a tailor-made heavy blue spectrum with a continuous spectral emission across PAR 400 - 700nm wavelength range. This is spectrum is dedicated to stimulating healthy root growth and improving root extension, while the overall balancing spectral output also ensures the healthy growth of leaves and stems.


FSV spectrum focuses on vegetative growth phases and propagation. The recipe delivers shorter, compact plants with a good biomass ratio – the high energy in the blue 450nm bandwidth also promotes stomata opening. All together a good balance between both photon levels guarantees a good mix between vegetative growth and biomass production.
