8 REASONS TO CHOOSE
STL GROWLIGHT CANNABIS INDOOR
1) 10 YEARS
10 years warranty or 50.000 working hours! It’s not just a slogan, but the logical consequence of all the following features.
2) High efficiency with
High efficiency with silicone optics! Since they focus the 100% of light energy just on plants, especially where the flowers and fruits are formed and in areas where sunlight does not penetrate.
3) with irradiation towards culture
Heat dissipation with irradiation towards culture; unlike all other LED lamps the STL Growlight products dissipate most of the heat from the front, in aluminium, with a benefit on plants similar to that of HPS lamps.
4) separated from the lamp body
External driver, separated from the lamp body to avoid thermal interference. In devices where the driver is placed inside the lamp body the driver temperature is higher, of 30-35 °C, that that of external one; in this way the life of electrolytic capacitors, that constitute the most critical component of the drivers, decreases of 6/8 times than that of a driver externally located.
5) Body lamp constitute
Body lamp constitute just of aluminium, silicone and stainless-steel screw, totally free of plastic parts which, notoriously, are less resistant than metals and silicones and they are less prone to yellowing and loss of transparency.
Compact size, just 4,35cm2/W to reduce shadow effect and thermal stress. Thermal stresses in linear lamps are the main cause of seal breakage and the consequent reduction of IP grade. That’s because the difference of dilation, between the aluminium case and the front in PMMA or polycarbonate, in a lamp of 150 cm easily surpasses 3mm and this stress occurs at each ignition and extinction.
7) Lamp body resistant
Lamp body resistant to immersion, deep and prolonged and also high-pressure water and steam jets, used for sanitising.
8) Use of components
Use of top-quality components: NICHIA for white LEDs, OSRAM for HyperRED; Meanwell for drivers.
