Led light holder on the water filter outlet of the inflatable mspa hot tub

In China at Ali I bought 3 waterproof led lights. (see images)
For this I made a holder that is clamped on the water filter outlet of the inflatable Mspa hot tub.
On the side of the water outlet are recesses where the holder clamps. Please note, not all recesses are open so that the holder only fits one way.
To allow enough filtered water to pass through the hot bub, enough distance is kept on the holder. In the evening, the Leds provide beautiful light under water.
