NO.1 Focusing on the swimming pool lights housing structure, high power led designed swimming pool lights can be changed into SMD types, but not all the SMD designed pool lights can be changed into high power led types, because there may be not enough space for the lens height.
NO.2 Lighting output angle, as mentioned above, high power led swimming pool light will have an angle of 30° or 45°, while SMD swimming pool lights have 120°angle.
NO.3 As they have different lighting output angles, the lighting effects underwater are different. High power led swimming pool light performs like a spotlight, the lighting output is narrow. SMD swimming pool light performs like a bulb, the lighting output is wide.
NO.4 SMD swimming pool lights will have a higher lumen output efficiency than high-power led pool lights.
