Aquarium lighting LED lamp 0.3, 0.5, 1, how to 3W penetration depth, grass cylinder 60CM water depth much
The greater the power, the stronger the ability to penetrate the water. 60 cm water depth, short dwarf pearls can not use LED lights, halogen lamps can only be used.
LED is a point source, penetrating power is relatively strong, the disadvantage is often small exposure area. The 1W lamp is very good plant. Keep only the green grass, and you can do it with metal halide lamps.
