Building underwater pool lights

Hi everyone.
I need to create a simple electronic circuit that will contain:
-LED Light (approximately 2000 lumens, 5000-6000K) probably 12v (depends on batteries)
-Batteries 12v (?) (LED should light all night)
- On / off switch waterproof
-Charging input waterproof
-Charger (separately) (need to charge 4-5 lights at the same time)

Could you recommend me exactly what parts should I use? (ebay, amazon, whatever)
waterproof casing will be design for those parts.

Everything should be pretty good quality, there is no budget limit for now.

Of course if you think I need more electrical parts, go ahead and tell me, but the circuit should be simple and working.

Welcome to the forums.

-Charger (separately) (need to charge 4-5 lights at the same time)
4-5 lights ? You'll need to give us some idea what you are thinking of here.

You still haven't given us info as to what you want.
Do you want lights to float on the surface and shine down in the water ?
Do you want a big blasting fixture at one end to light the water ?

We can help you with the guts but what are you going to put it in.
How long does it need to last between charges.

I want lights to be underwater, at the bottom of the pool to light the water.
Light should be working about 8 hours.
Waterproof casing will be design for those parts, so only charging input and on/off switch should be purpose-built to be underwater, its very important (IPX8).
I found these lights:
4pc 12 24V Round Warehouse Work Light LED Flood Lamp Indoor Outdoor 27W 2000LM | eBay

But its 27W. To supply that amount of power for 8 hours I need pretty big battery, too big for this project I think, so I can lower the criteria - lumens to 1200-1500.

Be very careful on the charger. Any primary to secondary current leakage could be fatal. Ground the SECONDARY to the pool bonding system.

Any rechargeable light will need to be removed from the pool to be recharged.
