Novice ask for LED water lamp selection
Select the type of lightWe understand that as long as the spectral peak of the lamp output coincides with the spectral range of chlorophyll a and B, the light emitted by the lamp can be used as a water lamp for the cultivation of aquatic plants.Through the introduction of various lamps, we also understand the advantages and disadvantages of various types of lights. As long as according to their own conditions, through comparison, to choose suitable for water lamp.Warning note: when you step into the world of light and water, you will find that the hidden knowledge is beyond your imagination. When the light source is applied to the cultivation of aquatic plants, the problems encountered may be very much. Would you think that choosing a light source would just pick up a high priced tube? Therefore, before choosing lamps, we must consider comprehensively.
Among them, the green aquatic plants are marked by low standard, and red ones are calculated by high standard. The calculated results can be used as a reference value, but also with the actual situation of the best water aquarium for comparison, if the water tank of all kinds of negative plants, then the calculated value may be slightly higher than the actual demand; if the water in the aquarium which is full of Qiang Guangshui grass, is calculated the value may also slightly lower than the actual demand. This time according to the theory of value to combine their own actual conditions to set the number of Duodawa aquarium oneself needs light.
Calculate the wattage of water tank lampIn fact, the demand for water lamps, Watts, in the water world has a widely circulated rough formula, you can calculate the theoretical value of demand. Remember, that's the theoretical value.In the case of fluorescent tubes (T5/T8) (other types of lamps are similar):Shallow tank: water depth in 30cm (not including bottom sand) below, each liter of water about the number of watts of water lamp is 0.5 ~ 0.6W;Medium tank: water depth of 30cm ~ 40cm, each liter of water about the number of watts of water lamp 0.7 ~ 0.8W;Deep tank: water depth of 40cm ~ 50cm, each liter of water about the number of watts of water lamp 0.9 ~ 1.0W.
