IP68 is a depth and a duration, not a promise
The best pool lighting for 2026
Pool lighting on this shelf is almost entirely cordless: rechargeable or battery LED units that float, sit on the floor, or clamp magnetically through a liner wall. The specification everyone quotes is IP68, and it is worth knowing exactly what it claims — continuous immersion, at a depth and for a duration the manufacturer states. IP68 without a stated depth is an incomplete specification, and a light rated to one metre in a 1,32 m pool is being used outside its rating. The second figure is the runtime, usually six to twelve hours, which is a season of evenings if the unit is fished out and charged, and a fortnight if it is not. Then the mounting, which is the real division on this shelf: a floating light lies on the surface and lights the terrace; a magnetic pair clamps through the wall and lights the water; a weighted unit sits on the floor and lights everything above it. Brightness is rarely given in lumens and often in LED count, which says nothing — where lumens are published, they are the figure to use. Colour control is RGB with a remote on nearly all of them, and the thing to check is the remote range through water, because radio and infrared behave very differently once the receiver is submerged. We compare IP rating with its stated depth, mounting, runtime and charging, brightness, colour modes and remote range.
